The Late Bronze Age Collapse and the Formation of Ancient Italian Peoples

Abstract

The collapse of the Mediterranean world at the end of the Bronze Age (around 1200 BC) had a profound impact on population movements and cultural change in the Italian peninsula. This paper comprehensively examines the influence of the Late Bronze Age collapse on the formation and origins of the ancient peoples of Italy from five perspectives: mythical tradition, genetic traces, archaeological and cultural evidence, historical background, and the estimation of migration routes. Mythical memories such as the Trojan War and the Etruscan origin myths contain echoes of the upheavals at the end of the Bronze Age【40†L1-L4】【34†L308-L315】, and analysis of genetic traces suggests that the origins of the Etruscans and other groups of the period were the result of complex interactions between indigenous populations and migrants from the eastern Mediterranean【6†L319-L327】【38†L119-L127】. Meanwhile, as cultural traces, archaeological data show that around the 12th century BC widespread changes such as cremation practices (urnfield culture) and mountain fortification appeared in Italy【29†L373-L381】【29†L334-L342】, which is consistent with the contemporaneous historical background of the movement of the Sea Peoples and the collapse of Mediterranean trade. Finally, on the basis of this evidence, we discuss the estimation of migration routes, demonstrating that the population movements that occurred through various routes at the end of the Bronze Age (the influx of Eastern European Indo-Europeans into Italy, migration from the Aegean–Anatolian direction, migration to southern Italy via the Balkan peninsula, and so on) contributed to the formation of the ancient peoples of Italy. By integrating diverse scholarly discourses on the origins of the ancient Italians, this study illuminates the process by which the crisis at the end of the Bronze Age reshaped the anthropological and cultural landscape of the region, and its lasting impact.

Introduction

At the end of the Bronze Age, around 1200 BC, a series of social collapses and upheavals occurred in the Mediterranean world. Historians refer to this period as the Late Bronze Age collapse, which is characterized by the fall of ancient civilizational spheres such as the Mycenaean and Hittite empires, the severing of international trade networks, and the movement and invasion of the so-called Sea Peoples【39†L497-L504】【39†L499-L506】. This great upheaval had repercussions not only in the eastern Mediterranean but also in the western Mediterranean and Europe, and is thought to have had an important influence on the social and cultural changes of the Italian peninsula and on the formation of the origins of ancient peoples.

The term ancient peoples of Italy refers to indigenous groups, both Indo-European and non-Indo-European, including the Etruscans, Latins, and Umbrians. Various theories about their origins have existed since antiquity: for example, Herodotus claimed that the ancestors of the Etruscans migrated from Lydia, whereas Dionysius and Livy emphasized their indigenous development【19†L150-L158】【38†L109-L118】. With the advances of modern archaeology and genetics, new evidence has been brought to bear on this debate. In particular, elucidating the influence of the population movements and environmental changes of the Late Bronze Age collapse on the ethnogenesis of Italy has become an interdisciplinary research topic encompassing archaeology, classical philology, and genetics.

This paper seeks to examine, on multiple levels, the influence of the Late Bronze Age collapse on the formation of the origins of the ancient peoples of Italy and on their genetic and cultural composition. To this end, it will (1) examine the traces of the Late Bronze Age upheaval that remain in mythical memories such as the Trojan War, (2) analyze the genetic traces revealed through ancient DNA and human-genetic research, and (3) examine the cultural traces and patterns of change apparent in the archaeological record. It will then (4) outline the historical background of the Late Bronze Age Mediterranean world and examine its connection with Italy, and (5) present an estimation of migration routes based on the various lines of evidence. Through this approach, the paper will comprehensively discuss how the crisis at the end of the Bronze Age reshaped the population distribution and cultural landscape of the Italian peninsula.

Mythical Memory

The events associated with the Late Bronze Age collapse are reflected in later Greco-Roman myths and legends and have been transmitted as mythical memory. A representative example is the Trojan War and the subsequent tradition of the migration of the Trojans. The ancient Romans traced their own origins to the migration of the Trojan hero Aeneas to Italy; according to tradition, after the fall of Troy around the 12th century BC, Aeneas led the surviving party and landed in the Latium region of Italy【40†L1-L4】. He merged with the indigenous people of Latium and founded a new dynasty, and the story that his descendants would eventually lead to the founding of Rome is recounted in works such as Virgil’s Aeneid. This myth shows that the Late Bronze Age event of the Trojan War (conventionally dated to around 1190 BC) is connected to the origins of the Italian people, and through it the later Romans came to perceive their ancestors as refugees from the end of the Bronze Age【40†L1-L4】.

Another tradition tied to the turmoil around the time of the Trojan War is the story of Antenor. Antenor was an elder of Troy who, after the war, is said to have fled his homeland and settled in northern Italy. According to ancient Roman histories and Virgil’s epic, Antenor led the Paphlagonians—who had been allies of Troy—across the Adriatic Sea, became the ancestor of the Veneti, and founded Padua (Padova)【35†L1-L9】【35†L11-L18】. Such myths—of refugee groups originating in the Trojan War settling in various parts of Italy—can be interpreted as cases in which the memory of population movements at the end of the Bronze Age was later adapted into myth.

The Greco-Roman traditions concerning the origins of the Etruscans are also noteworthy. According to what he recorded in the 5th century BC, Herodotus wrote that the Etruscans (Tyrrhenians) were originally from Lydia in Asia Minor and, fleeing a severe famine, migrated to Italy under the leadership of Tyrrhenus, the son of the Lydian king【19†L150-L158】. This story alludes to a crop failure and emigration in the Anatolian region around the end of the Bronze Age, and explains that the group that later became the Etruscans crossed the Aegean Sea. Meanwhile, Hellanicus, a historian contemporary with Herodotus, claimed that the Etruscans were originally Pelasgians from Thessaly in northern Greece who entered Italy by way of the Adriatic Sea【19†L150-L158】. These mythical traditions are the product of efforts by the ancients—who took note of the heterogeneity of Etruscan civilization (such as their use of a non-Indo-European language)—to seek its origin in external migration. Although modern archaeology tends strongly to regard Etruscan culture as having developed indigenously【19†L169-L177】【38†L119-L127】, one cannot rule out the possibility that these myths represent a memory of the influx of external groups at the end of the Bronze Age.

The tradition of the Umbrians (Umbri), who are portrayed as having been pushed out by the Etruscans, is also of interest. Ancient authors mention that the Umbrians were the oldest people in Italy and connect their name to the Greek “ὄμβρος (ómbros, shower, rain, downpour),” transmitting an etymological theory that they were “those who survived the heavy rains (the great flood)”【44†L313-L320】. Pliny the Elder introduced the tradition that “the Umbri (Ombrii) were those who endured the great flood after the downpour,” which may be a mythologization of the memory of ancients who experienced sudden disasters at the end of the Bronze Age. Dionysius also recorded that the Umbrians were originally spread widely throughout Italy but were later pushed back and reduced in power by the Pelasgians and the Lydians (the Tyrrhenians, i.e., the Etruscans)【44†L280-L288】【44†L289-L297】. This tradition, too, is interpreted as reflecting the processes of ethnic migration and conquest after the end of the Bronze Age. In short, the legend of the Umbrians, regarded as the “oldest Italians,” can be seen as a mythical memory reflecting the historical reality of the struggle between existing inhabitants and new migrants at the end of the Bronze Age.

Meanwhile, since the Trojan War itself overlaps temporally with the Late Bronze Age collapse, some scholars hold that the story of the Trojan War contains an intermingled memory of the movements of the Sea Peoples and the collapse of Mediterranean trade【39†L497-L504】【39†L499-L506】. For example, the story of survivors such as Aeneas and Antenor scattering to various parts of the world after the fall of Troy can be interpreted as a mythical projection of the great migration in which, in actual history, various peoples left their homelands at the end of the Bronze Age in search of new lands. In particular, the route by which Aeneas settled in Italy by way of Carthage, and the route by which Antenor crossed the Adriatic Sea, plausibly correspond to the maritime and overland migration routes of the Late Bronze Age to the Early Iron Age. Although these myths are not literal historical records, they bear witness to how deeply the turmoil and changes at the end of the Bronze Age were imprinted on the collective memory of later peoples.

To summarize, mythical memories such as the tale of Aeneas as the origin of Rome, the Etruscan origin myth based on the Lydian famine theory, and the legend of the Umbrians surviving an ancient flood are cases in which the shock of the Late Bronze Age collapse remains within the origin stories of each people. When matched against the archaeological and genetic evidence discussed below, these memories—transmitted indirectly through myth and legend—may reflect certain historical facts, and can be interpreted as the collective trauma and memory of migration that the crisis at the end of the Bronze Age inscribed on the Italian peninsula【34†L308-L315】.

Genetic Traces

Ancient DNA analysis and human-genetic research provide new insights for elucidating the origins and migration patterns of the ancient population of the Italian peninsula. In particular, the origin of the Etruscans has long been a subject of debate, and several studies have been conducted to trace the genetic traces of the population movements associated with the Late Bronze Age collapse.

Ancient DNA studies conducted in the early 2000s raised the possibility that the genetic origins of the Etruscans were connected with the eastern Mediterranean. Vernesi et al. (2004) analyzed the mitochondrial DNA (mtDNA) of 30 Etruscans from the 7th–3rd centuries BC and reported that the genetic lineage of the Etruscans shows a closer relationship to populations of the eastern Mediterranean coast than to modern Italians【6†L319-L327】. In this study, the mtDNA haplotypes found in the Etruscans belonged to European or West Asian (western Anatolian) lineages, but types exactly matching those of modern people were said to be rare【6†L321-L328】. While noting the possibility that the Etruscan population was genetically extinguished after being assimilated into Rome, this result also suggested that an eastern Mediterranean (e.g., Anatolian) element was included in the origin of the Etruscans【6†L319-L327】. In short, early genetic research supported a genetic connection between the Etruscans and the eastern Mediterranean, providing room for an interpretation consistent with Herodotus’s migration theory.

Even when examining not the genes of all modern Tuscans but only certain regions in the heartland of Etruscan civilization, traces of eastern Mediterranean origin were detected. Achilli et al. (2007) investigated the mtDNA variation of modern Tuscans and found that the frequency of Near Eastern mtDNA haplogroups was unusually high at 17.5% among the residents of Murlo, a small village in southern Tuscany【10†L46-L54】. This proportion was an exceptionally high figure compared with other regions of Italy, and the researchers held that it suggested a direct and relatively recent influx of Near Eastern (Anatolian) ancestry into the Murlo region【10†L46-L54】. Interestingly, Murlo is known to have been a region belonging to the ancient Etruscan urban sphere, so this result can be connected with the hypothesis that some of the ancestors of the ancient Etruscans (especially the ruling class) came from the Near East. However, since this study targeted modern people, whether the influx of these Near Eastern genes occurred in the Etruscan era (the end of the Bronze Age to the early Iron Age) or was the effect of later (Roman imperial or medieval) immigration was a matter requiring further discussion【10†L50-L54】. Nevertheless, the common notion that “the genes of the Etruscan aristocracy resemble those of eastern Mediterranean peoples” once drew attention on the strength of such results.

However, since whole-genome analysis of ancient skeletal remains became possible from the 2010s onward, a more precise picture has been drawn of the genetic identity of the Etruscans and other Iron Age Italians. In 2021, Posth et al. published a study tracing the origins and legacy of Etruscan civilization by analyzing the genomes of 82 individuals dating from 800 BC to AD 1000 excavated from the Etruscan heartland and southern Italy【38†L97-L105】. The most central result of this study was that the Etruscans, despite their distinctive culture, were genetically very close to neighboring Italian groups (e.g., the Latins)【38†L99-L107】【38†L119-L127】. That is, the genomic profiles of the Etruscans and the Latins of the Latium region of the same BC period were so similar as to be nearly indistinguishable, and it emerged that both groups shared a substantial portion of steppe-lineage (Indo-European) ancestry that had arrived in Italy during the Bronze Age【38†L119-L127】. Furthermore, this study reported that it found no evidence of a recent influx of Anatolian-lineage population in the genome of the Etruscans, and thus did not support the hypothesis that there had been large-scale migration from Lydia and elsewhere, at least around the Iron Age【38†L119-L127】. With this, in the long-standing debate over “whether the Etruscans were the product of foreign migrants or of indigenous development,” genetics in effect lent weight to the theory of indigenous origin【38†L109-L118】【38†L119-L127】.

What is interesting is the fact that the Etruscans, who were genetically almost homogeneous with Indo-European-speaking groups such as the Latins, used Etruscan, a non-Indo-European language. Posth et al.’s study pointed out this as “a very peculiar phenomenon”【38†L148-L156】 and proposed scenarios to explain the discrepancy between genetic continuity and language. The research team noted the possibility that the Indo-European-speaking groups who entered Italy during the broader Bronze Age (the 2nd millennium BC) were linguistically assimilated into the already-established Etruscan-speaking population【38†L154-L161】. In other words, over the course of the long-term population mixing and cultural contact that proceeded from the end of the Bronze Age into the early Iron Age, the language of a minority group (Etruscan) maintained a dominant position, and a peculiar pattern of assimilation occurred in which the majority of migrants (the Indo-Europeans) adopted that language【38†L154-L161】. Such a hypothesis brings to mind the possibility that there may have been some difference in origin between the Etruscan aristocratic class and the commoner class. That is, it is a scenario in which a relatively small group of natives/migrant aristocrats (the holders of Etruscan) dominated or absorbed the more numerous Indo-European commoner groups that flowed into early Iron Age Italy, forming a single cultural sphere. Indeed, in Etruscan society the existence of an upper class stands out in features such as large tumuli (mound tombs) and grave goods, which in effect suggests the plausibility that this class had a culturally distinct origin. However, the ancient DNA evidence to date has not directly demonstrated a sharp genetic difference between aristocrats and commoners, and overall it shows that the population of the Etruscan region maintained a relatively homogeneous gene pool over a long period【38†L161-L167】. Therefore, the hypothesis that “only the Etruscan aristocracy was of foreign origin” has not yet been confirmed, but it remains one possibility for explaining the language–gene discrepancy.

In the case of the other ancient peoples of Italy as well, genetic traces of population movements around the end of the Bronze Age can be found. The so-called Italic Indo-European tribes (Italici), such as the Latins, Sabines, and Umbrians, genetically share a substantial portion of lineages of Central and Eastern European origin (e.g., steppe ancestry), which is consistent with the fact that their languages belong to the Indo-European family【38†L119-L127】. This genetic component points to a population group newly introduced into Italy from the north/east roughly after the middle of the 2nd millennium BC, and archaeologically this period corresponds to the latter part of the Bronze Age (including the time around the Late Bronze Age collapse). In other words, genetics supports the idea that a population of Central European lineage entered Italy at the end of the Bronze Age and mixed with the existing inhabitants, and that this group became the ancestor of the early Italic-branch groups such as the Latino-Faliscan and Umbro-Sabellic peoples【38†L119-L127】. Meanwhile, the genes of the Sardinians have a distinctiveness that sets them apart from the Italian mainland, and it is presumed that external influx after the Bronze Age was relatively limited. However, even in Sardinia, through DNA comparison studies between Nuragic-era (Bronze Age) residents and modern people, some traces of contact with the eastern Mediterranean have been found (for example, reports of Y-chromosome lineages shared with some eastern Mediterranean groups). This suggests that Sardinia was an important hub on the migration routes of the Sea Peoples. Together with the case of the Etruscans, these results show that the Late Bronze Age collapse was accompanied not by a simple fall of civilization but by a reorganization of the population, the aftermath of which is also imprinted on today’s gene pool.

Cultural Traces

The Late Bronze Age collapse brought about abrupt changes in the archaeological cultural patterns of the Italian peninsula. The cultural traces confirmed through the archaeological record clearly show that new funerary customs, settlement forms, and shifts in material culture took place in Italy at that time. These changes appeared in similar patterns simultaneously in several regions far apart from one another, suggesting that they were part of the international turmoil at the end of the Bronze Age.

First, one may point to changes in funerary culture. Until around the 12th century BC, the Terramare culture of northern Italy and the Apennine culture of the central-south had a mixture of inhumation and partial cremation, but after the end of the Bronze Age the custom of cremating the dead and burying the remains in urns (urn burial) spread throughout Italy【34†L254-L258】【29†L334-L342】. This is a common feature of the culture known as Italy’s Proto-Villanovan culture of the latest Bronze Age to early Iron Age, and it appears extensively from the north to the south and as far as Sicily【29†L334-L342】. A notable point is the fact that this urnfield culture is closely connected with the contemporaneous ‘Urnfield culture’ of Central Europe【29†L334-L342】. Indeed, the cemeteries of the Proto-Villanovan style have a Central European character and strongly suggest that new customs and people flowed into Italy around the end of the Bronze Age【29†L334-L342】. This is an example of cultural variation appearing in common even between distant regions; for instance, it means that the cremation custom that began in Central Europe, such as in Bohemia or Bavaria, spread across the Alps to Italy. Moreover, this kind of innovation in funerary culture is also chronologically consistent with the Aegean region. In late Mycenaean (12th-century BC) Greece as well, some cremation customs appeared, which is interpreted as the influence of northern culture and was part of a pan-European cultural shift at the end of the Bronze Age.

One may also point to the similarity of tomb structures and grave goods. In the cemeteries of the early Iron Age Etruscan Villanovan culture, biconical urns (pottery) covered with helmet-shaped lids are excavated, and this form resembles the artifacts of the Central European Hallstatt culture and Urnfield culture spheres. In addition, similarities with the eastern Alpine region are observed in the styles of weapons (swords, spears) and ornaments (brooches, comma-shaped beads, etc.). Such archaeological data show that the funerary and material cultures of peoples far apart from one another became considerably similar over the Late Bronze Age/Early Iron Age period, which is regarded as evidence of population movement or long-distance exchange. That is, it can be said to be the product of the mixing and spread of cultural elements from various regions during the turbulent period at the end of the Bronze Age.

Changes in settlement structure and defensive systems are also conspicuous. The Terramare settlements of northern Italy, which had settled and flourished in fertile plains until the latter part of the Bronze Age, declined sharply around the 12th century BC and most were abandoned【34†L295-L303】. And the new settlements that appeared afterward in various parts of Italy show a clear tendency to be located on mountainous terrain or hills favorable for natural defense【29†L373-L381】. Archaeologists have found that during the Final Bronze Age of 1150–950 BC, a widespread phenomenon of abandonment of lowland settlement and preference for highland fortified villages took place among the people of Italy【29†L373-L381】. For example, the Sorgenti della Nova site in the Etruscan region was established around the 10th century BC as a 5-hectare hill-fort, and on its summit, along with defensive facilities, a division presumed to be the residence of the ruling class has been identified【29†L373-L381】. In southern Italy and Sicily as well, many of the existing coastal and lowland settlements of this period were reduced or abandoned, and hilltop villages appeared instead. This phenomenon is also consistent with the situation in contemporaneous mainland Greece, where, after the collapse of the Mycenaean palaces, the population took refuge on fortress hills or in caves. This is interpreted as a change reflecting the instability of Late Bronze Age society and the increased need for defense, and the commonality of mountain fortresses and settlement structures eloquently attests that Italy was part of the pan-Mediterranean crisis at the end of the Bronze Age.

The material-cultural exchange of Late Bronze Age Italy is also noteworthy. The Frattesina site in the Po River basin of northern Italy was a center of trade and workshops that flourished over the 12th–9th centuries BC, and there both eastern Mediterranean pottery fragments (vessel fragments of the Late LH IIIC) and Italian-made imitation Mycenaean-style pottery were found【29†L339-L347】【29†L348-L357】. In addition, large quantities of raw materials and crafts such as bronze, glass, ivory, and amber were excavated, showing that Frattesina actively participated in the Late Bronze Age Mediterranean trade network【29†L348-L357】. Among these, the excavation in particular of amber (from northern Europe) and ostrich eggs (from North Africa) means that even at the end of the Bronze Age, some trade routes were maintained or newly developed. Meanwhile, traces of contemporaneous Mediterranean exchange are also vivid in Sardinia and Sicily. Sardinian Nuragic pottery has been excavated from the 13th–12th-century BC strata of Kommos on Crete and Pyla-Kokkinokremos on Cyprus, and conversely, within Sardinia as well, Mycenaean pottery and Cypriot bronze ingots have been found【15†L563-L571】【15†L581-L590】. Such archaeological evidence shows that at the end of the Bronze Age the activity of the Sea Peoples reached as far as the central Mediterranean, and that the Italian islands and the Aegean and Levant regions were connected in a complex network【15†L579-L588】【15†L595-L603】. In particular, the view that interprets some of the Sea Peoples appearing in the records of the Egyptian pharaohs as Sardinians, Sicels, and Tyrrhenians is also consistent with the archaeological data【15†L603-L612】【21†L23-L30】. For example, there is the hypothesis that the Sherden correspond to Sardinia, the Shekelesh to the Sicel people of Sicily, and the Teresh to the Tyrrhenians (Etruscans)【21†L23-L31】. Indeed, insofar as a cultural transformation and external influence is detected in Sardinia and Sicily at the end of the Bronze Age, the possibility is raised that some of the Sea Peoples were from these regions, or conversely that remnant forces of the Sea Peoples who had been defeated in the eastern Mediterranean at the end of the Bronze Age settled on the western Mediterranean islands.

Examining the cultural variation of the ancient peoples of each region, the changes of the Late Bronze Age and Early Iron Age show a pattern that was differentiated by region while at the same time mutually interconnected. The Villanovan culture (around the 9th–8th centuries BC), regarded as the ancestor of the Etruscans, was an Iron Age culture that developed from the aforementioned Proto-Villanovan cremation custom, and was the result of new elements fused with the indigenous Bronze Age culture【19†L177-L185】. The early Latin culture of the Latium region (the Latial culture) also had an urn-burial tradition similar to that of the Villanovan, while showing its own distinctive features, such as the use of hut-shaped urn lids (hut urns). The Sabellic tribes of the central interior, including those of Umbria, appear to have been influenced by the Villanovan culture while maintaining some indigenous Bronze Age traditions. For example, the Pianello di Genga cemetery (10th–8th centuries BC) in the Umbria region had a large-scale urn cemetery of more than 500 burials, but traces of internal social distinction were faint, suggesting a relatively egalitarian communal burial【29†L379-L387】. This contrasts with the weapon grave goods and small number of elite tombs seen in the cemeteries of the Etruscan region of the same period【29†L355-L363】【29†L373-L381】. Such differences may reflect a divergence in local social structure, but they were fundamentally variations upon the common foundation of the urn-burial culture.

To summarize, the cultural traces of the Late Bronze Age brought to the Italian peninsula new funerary customs (urn cremation), fortification of settlement forms (hilltop settlements), and foreign influence on material culture, and these were phenomena that appeared similarly across distant regions at the time. Thus the Late Bronze Age collapse was accompanied not by simple destruction but by a reorganization of culture, and the new cultural patterns that formed as a result became the background for the emergence of the various ancient peoples of Italy (the Etruscans, Latins, Umbrians, etc.). In other words, the crisis at the end of the Bronze Age became an occasion for cultural innovation and fusion, and through it, as the Italian peninsula entered the Iron Age, its ethnic landscape was newly composed.

Historical Background

To understand the Late Bronze Age collapse, it is necessary to briefly examine the historical situation of the eastern Mediterranean at the time. Over the 13th–12th centuries BC, a chain of upheavals occurred in the Aegean and West Asia. The Mycenaean palaces of Greece were burned, the Hittite empire fell, and Egypt barely repelled the invasion of a coalition of numerous foreign peoples (the invasion of the Sea Peoples)【39†L497-L505】【39†L499-L506】. Modern historiography holds that the causes of this phenomenon were a complex combination of prolonged drought and famine caused by climate change, natural disasters such as earthquakes, changes in the nature of warfare brought about by innovations in weapons and tactics (iron weapons and massed infantry tactics), and the collapse of international trade networks【34†L299-L307】. These factors became intertwined and brought down the hyper-connected world system of the Late Bronze Age, bringing about a regional dark age【26†L15-L18】.

The Italian peninsula was located on the periphery of this eastern Mediterranean collapse, but it was not free from its sphere of influence. The case of the fall of the Terramare culture of northern Italy attests to this. The Terramare culture was a distinctive palisaded-settlement culture of the plains of the Po River basin that flourished from the Middle Bronze Age, but a crisis began at the start of the 12th century BC, and it completely collapsed around 1150 BC【34†L295-L303】. As for the cause by which a population numbering in the hundreds of thousands vanished all at once, it is interpreted that environmental destruction caused by overexploitation and successive droughts lowered agricultural productivity, resulting in economic collapse and large-scale famine【34†L299-L307】. Indeed, geological-climatic data show a sudden decrease in precipitation and cooling called the 3.2 ka event around 1200 BC, suggesting the possibility that not only the eastern Mediterranean but also northern Italy experienced severe drought for centuries【34†L299-L307】. The Terramare people appear to have abandoned their existing settlements and carried out a mass migration, probably in the face of this kind of ecological catastrophe and food shortage. Interestingly, Dionysius’s record has a passage reminiscent of this. He wrote that “two generations before the Trojan War, the Pelasgians of the Po River basin suffered from a crop failure of unknown cause and departed southward”【34†L308-L315】, which may be a mythologization of the southward movement of the Terramare population. Indeed, the statement that, after the end of the Bronze Age, a group of northern origin came down to central Italy and fused with the indigenous inhabitants (the Aborigines of whom Dionysius spoke) is judged to reflect, to a considerable extent, the historical reality【34†L308-L315】. In other words, the Italian version of the Late Bronze Age collapse event—the collapse of the Terramare—was in effect recorded in later histories as “the migration of the Pelasgians.”

The invasions of the Sea Peoples depicted on the stelae of the Egyptian pharaohs Merneptah and Ramesses III (13th–12th centuries BC) are a symbolic event of the collapse of the international order at the end of the Bronze Age. According to these records, a coalition of various tribes—the Sherden, Shekelesh, Ekwesh, Lukka, Peleset, Denyen, Teresh, and others—came pouring in by sea and land and ravaged the Mediterranean coast【21†L9-L17】. Modern researchers have inferred the identities of these Sea Peoples on the basis of literary and archaeological data. Among them, the view that the Sherden are related to the Nuragic people of the island of Sardinia was raised early on【21†L33-L37】. Indeed, the equipment such as the helmets and round shields depicted on the Sherden mercenaries in Egypt is similar to artifacts excavated in Sardinia, and the phonetic value “SHRDN” also accords with Sard (Sardinia). Likewise, there are interpretations that connect the Shekelesh with the Sicel people (Siculi) of Sicily, and the Teresh with the Etruscans (Tyrrhenoi) or with the Trojans (Tros) of Asia Minor【21†L23-L31】【21†L35-L40】. If these identifications are correct, it means that western peoples (from Italy and the Aegean islands) actively participated in the wars of the eastern Mediterranean at the end of the Bronze Age. The archaeological record of Sardinia and Sicily shows the rise of fortification and warrior culture in this period, and there is also a view that this suggests they were not mere victims but acted as the core of armed forces. That is, possibilities are discussed such as that some of the Nuragic warrior groups of Sardinia set out on expeditions to the east and, after failing, returned and brought about changes in Sardinian society, or, conversely, that eastern Mediterranean migrants fleeing the pressure of the Sea Peoples settled in Sardinia and Sicily and brought about a transformation of the local culture.

These circumstances show that the Italian peninsula was a peripheral stage of the international upheaval at the end of the Bronze Age. That is, although it did not undergo the extreme collapse experienced by the Hittites or Mycenaeans—where states were overthrown or writing was discontinued—its social structure and population composition were changed by indirect shocks and aftereffects. Furthermore, the collapse of trade networks at the end of the Bronze Age restricted the circulation of metal resources and goods, hastening the promotion of iron use in Italy and the transition to a self-sufficient economy【26†L11-L18】. Indeed, hubs such as Frattesina grew within the new, decentralized trade system of the end of the Bronze Age, and this system differed in character from the previous palace-led trade【29†L348-L357】. This means that a reorganization of the socioeconomic structure occurred through the Late Bronze Age crisis. As a result, by around the 10th century BC, Italy came to possess a society of a new character distinct from the previous era, and this became the background for the birth of the various peoples who preceded ancient Rome.

To summarize, as a historical background, the Late Bronze Age collapse is characterized by a complex situation comprising the fall of the wider civilizational sphere surrounding Italy, climate crisis and food shortage, large-scale population movements (invasions and escapes of foreign peoples), and the decline of international trade. Within this macroscopic background, the local societies of Italy sought adaptations for survival, and in the process they formed new ethnic identities through population movement and fusion and cultural innovation and acceptance. The Trojan War was one part of this historical upheaval and, imprinted in myth, exerted an influence even on the origin narratives of the Italian peoples. As the final part of this paper, under this historical background, we will comprehensively estimate which specific migration routes contributed to the formation of the ancient peoples of Italy.

Migration Route Estimation

The diverse migration routes that occurred during the turbulent period around the Late Bronze Age collapse directly influenced the later distribution and origins of the ancient peoples of Italy. On the basis of the mythical, genetic, and archaeological evidence examined above, the major migration routes and settlement patterns can be estimated as follows.

  1. The Northern–Alpine route (the southward movement of the Italic peoples): This is the route by which Indo-European groups belonging to the Urnfield culture sphere of Central Europe crossed the Alps and entered Italy. They appear to have moved southward gradually over the Late and Final Bronze Age and settled in the Po Plain and central Italy【16†L53-L60】【29†L334-L342】. The archaeological evidence is that the Urnfield-lineage Canegrate culture appeared in northwestern Italy around the 13th century BC, followed by the spread of the Proto-Villanovan culture throughout Italy in the 12th–11th centuries BC【16†L53-L60】. The groups that entered via this route are presumed to have become the core ancestors of the Italic-branch tribes, such as the Latins, Umbrians, and Sabellians. The southward movement of the Pelasgians mentioned by Dionysius also seems, in historical context, to point to this kind of northern migration【34†L308-L315】. Genetically too, their movement remains in the Italians as a steppe-lineage admixture【38†L119-L127】, and linguistically the Indo-European language they spread developed into Latin and the Sabellic branch. This route most likely accounted for the largest share of the population composition of Iron Age Italy in terms of scale.

  2. Internal movement within the Apennine peninsula (the southward movement of the Terramare people): This is the route of the internal migration within the Italian peninsula of the residents of the Po valley region caused by the collapse of the Terramare culture at the end of the Bronze Age. Some of the Terramare people crossed the Alps to the north, while many are thought to have moved southward along the Apennine Mountains into central and southern Italy【34†L299-L307】【34†L308-L315】. In the course of their southward movement, they merged with the existing Apennine-culture groups (the proto-Italian indigenous people, Dionysius’s “Aborigines”), and as a result, along with the spread of the Proto-Villanovan culture, new ethnic groups were established. For example, some northern migrants settled in the Umbria region and contributed to the formation of the Umbrians, while others advanced further south and were involved in the formation of the Oscans of Campania or other Sabellic tribes. This route is basically an extension of the aforementioned Northern–Alpine migration, but it has the aspect of being a relocation of the existing inhabitants of Italy rather than of a purely external force. Therefore, the ethnic formation resulting from it often showed cultural continuity. For example, the fact that the Umbrian language remained as part of the Sabellic group, close to Latin, suggests that they were basically a branch of the northern migrants【44†L301-L307】, and at the same time, the fact that the Umbrian tradition called themselves “the oldest people” can be understood as a result of emphasizing the continuity of indigenous culture.

  3. The eastern Mediterranean–maritime route (Aegean/Anatolian migration): This is the route of groups that crossed directly to Italy by sea from the Aegean or West Asia. The Lydian–Tyrrhenian sea route in Herodotus’s Lydian tale belongs here【19†L150-L158】. Specifically, it is the scenario in which some residents from western Asia Minor (Lydia) crossed the sea and landed on the west coast of central Italy (the Tyrrhenian Sea coast), becoming the ancestors of the Etruscans. The name of “Prince Tyrrhenus” who appears in this tradition is the same as the Greek name for the Etruscans (Tyrrhenoi), and so it has been widely discussed since antiquity. Although no clear trace of mass migration has been found archaeologically, the similarity between the Etruscan language and the Lemnian language was a clue supporting this route. The inscriptions from around the 6th century BC found on Lemnos, a small island in the northern Aegean, were deciphered as a language very close to Etruscan, which suggests a human connection between the Etruscans and the Aegean world【19†L185-L193】. In the past, this was also taken as evidence proving that the original homeland of the Etruscans was the Aegean, but recently there is also a view that seeks to reinterpret it as a footprint left by the Etruscans advancing into the eastern Mediterranean【19†L185-L193】. That is, the Etruscan-related language of Lemnos may be a trace of a colony formed locally by Etruscan merchants or mercenary groups【19†L185-L193】. Whichever interpretation is taken, it does not deny that maritime movement existed between the Etruscans and the Aegean. Meanwhile, the migration route of the Trojan refugees after the Trojan War is also a kind of eastern Mediterranean–Italy sea route. Aeneas’s party is said to have left Troy in Asia Minor, passed through the Aegean Sea, stopped at Tunisia (Carthage), and reached Italy【40†L1-L4】. Antenor, in another tradition, is said to have come to Italy from Troy by way of the northern part of mainland Greece, entering through the Adriatic Sea【35†L1-L9】. In actual history too, around the fall of Troy (the end of the Bronze Age) there may have been movements such as some Aegean residents fleeing to the west, or, conversely, victorious Greek mercenaries advancing into Sicily and Italy. The migrant groups that reached Italy via this route may have influenced local society as an elite group, even if they were not large in number. For example, some of the early Etruscan aristocratic families may have claimed an Aegean (Trojan or Asia Minor) lineage to legitimize their ruling authority. The eastern Mediterranean mitochondrial DNA found in genetic analysis, or the Near Eastern/North African ancestry of a small number of individuals, may be traces of such maritime migrants【10†L46-L54】【38†L161-L167】.

  4. The Balkan–Adriatic route (migration to eastern Italy): This is the route of migration to southern Italy from the Balkan peninsula across the Adriatic Sea. Judging from archaeological and linguistic data, around the 12th–11th centuries BC, some tribes of the Illyrian peninsula appear to have crossed the Adriatic strait and settled in the southeast of Italy. In particular, the Iapyges or Messapii tribes of Apulia (today’s Puglia region) are known to have had this kind of background. The Messapic language is an Indo-European branch, and a possible connection with the Illyrian language is discussed, and their own tradition also mentions ancestors who came from across the sea. Amid the turmoil at the end of the Bronze Age, some of the residents of the Illyrian coast may have crossed the sea and migrated to southern Italy, which was relatively empty of people. This route is also reflected in myth, with the story being transmitted that Diomedes of Greek mythology founded a kingdom in southern Italy after the Trojan War. Indeed, the legend of Diomedes is transmitted as the founding story of several cities on the Apulian coast, which suggests that people from Aetolia (western Greece) crossed over to Italy. This Balkan–Italy connection adds to the diversity of Italian ethnic formation. That is, a structure was formed in which there were Greek-Illyrian migrant groups (the Messapii) on the east side of the peninsula and the Etruscans, Latins, Sabellians, and others on the west. This kind of multiple migration can be seen as the cause by which Italy came to have a pluralistic ethnic composition after the end of the Bronze Age.

  5. The Mediterranean island route (Sardinia and Sicily and their surroundings): Finally, in connection with the movement of the Sea Peoples at the end of the Bronze Age, one may mention the route by way of Sardinia and Sicily. As mentioned earlier, some of the Nuragic people of Sardinia or the Sicel people of Sicily went on expeditions/migrations toward the eastern Mediterranean, and conversely, some of them may have returned, or other groups may have flowed into these islands【15†L579-L588】【15†L595-L603】. For example, among the Sea Peoples, the Denyen are surmised to be the tribe of Dan in the Bible or the Danaans of Greece, but some also connect them with the Siculi of eastern Sicily. Archaeologically, the Frilisina culture of Sicily (also called the Pantalica culture) is a culture that newly appeared at the end of the Bronze Age, and it shows Cretan-Mycenaean influence while also possessing indigenous elements, suggesting a complex origin. This was probably a by-product of the movement of the Sea Peoples. In the case of Sardinia as well, a sudden change in the Nuragic culture around the 10th century BC is observed (the abandonment of some large Nuragic forts, the appearance of new styles of pottery, etc.), which is also connected with a severance from the eastern Mediterranean after the era of the Sea Peoples or a small-scale influx of migrants. Until the Phoenicians and Greeks established colonial cities in Sardinia and Sicily in later historical times, these movements of the Late Bronze Age to Early Iron Age would have influenced the ethnic composition of the two islands. For example, the origin of the Sardinian Shardana and the Elymians (Elimi) of Sicily is still unclear, but some theories connect them with Trojan War refugees or the Sea Peoples. The Elymians were the people who built Segesta, Eryx, and other places in western Sicily, and although tradition holds that they came from Troy, the truth of this is uncertain. But such legends of various routes attest that, in the Late Bronze Age to Early Iron Age, the aftereffects of population movement reached as far as the western Mediterranean, including Sardinia and Sicily.

The five routes above operated in a complex manner rather than being mutually exclusive. For example, a composite scenario is entirely possible, in which a band of Indo-Europeans who migrated via the Northern–Alpine route mixed with a southward-moving Terramare group to form a new tribe, to which a minority of eastern Mediterranean maritime migrants were added as a ruling class. In actual history, the formation of a people is often the result of the overlapping of many different lineages. In the case of the Etruscans, one might also view it as a unique mixture in which a northern element (the Urnfield culture) served as the foundation, to which indigenous Eneolithic (Early Bronze Age) lineages and a very small Aegean element were added. The Latins likewise possess a tradition fusing northern migrants + indigenous Latium inhabitants + legendary figures of Trojan lineage. These multilayered routes of Italian ethnic formation are a direct product of the turbulent period that was the end of the Bronze Age.

Conclusion

The collapse of the Late Bronze Age (around 1200 BC) was an event that shook the entire Mediterranean world, and it had a profound impact on the formation of the ancient peoples of the Italian peninsula as well. In this paper, we analyzed that impact through a multifaceted examination encompassing myth, genetics, archaeology, and historical records. The main conclusions can be summarized as follows.

First, mythical tradition reflects the memory of the upheaval at the end of the Bronze Age. The myth of Aeneas’s coming to Rome after the Trojan War, the legend of the Lydian famine and Etruscan migration, the tale of the Umbrians surviving a flood—all of these are interpreted as mythologizations of the realities of the war, famine, and migration that occurred at the end of the Bronze Age【40†L1-L4】【34†L308-L315】. Through them, the later Italians narrativized their own origins as survivors of a great upheaval or descendants of refugees.

Second, the genetic evidence shows that the formation of the Italian peoples was a complex result of the indigenous and the foreign. Ancient DNA analysis of the Etruscans confirmed that they were genetically similar to the neighboring Latins, with the majority being of indigenous origin【38†L119-L127】. At the same time, although in a minority, traces of eastern Mediterranean/Near Eastern lineages also exist, suggesting the possibility of a small-scale influx of migrants at the end of the Bronze Age or the beginning of the Iron Age【6†L319-L327】【10†L46-L54】. In particular, the language–gene discrepancy phenomenon (the maintenance of the Etruscan language) implies that a process of cultural assimilation occurred at the end of the Bronze Age to the beginning of the Iron Age, which makes possible a new interpretation of the hierarchical and cultural fusion of the society of the time【38†L154-L161】.

Third, the cultural and archaeological evidence shows that widespread cultural innovation and change took place in Late Bronze Age Italy. The spread of cremation customs and urn burials throughout the region【29†L334-L342】, the appearance of mountain fortified villages【29†L373-L381】, and changes in material culture (the styles of pottery and weapons) are all reflections of the population movement and exchange of that period. In particular, the fact that this kind of change took place simultaneously with other regions of Europe and the eastern Mediterranean attests that Italy was part of an international simultaneous crisis. As a result of this change, a new cultural sphere (such as the Villanovan) was established in Italy at the threshold of the Iron Age, and this became the foundation of the cultures of the ancient peoples such as the Etruscans, Latins, and Umbrians.

Fourth, viewed in historical context, the Late Bronze Age collapse was a complex crisis of famine, war, the movement of the Sea Peoples, and the severance of trade, and it was a transitional period in which the existing order collapsed and a new order was formed【34†L299-L307】【39†L497-L504】. In Italy, one cross-section of this crisis can be confirmed through cases such as the collapse of the Terramare culture, and its memory remains in old records such as those of Dionysius【34†L308-L315】. Without this background, the patterns of the subsequent emergence of the Italian peoples would also have been different.

Fifth, through the analysis of migration routes, we traced the several streams of population that flowed into the Italian peninsula. The southward movement of Central European Indo-Europeans, the internal re-movement of the residents of the Po valley, the maritime migration of people from the Aegean–Anatolia, movement via the Balkan peninsula, and the back-and-forth movement mediated by Sardinia and Sicily are all parts of the mosaic of origins of the ancient Italians. These routes operated in a complex manner, causing groups with pluralistic origins, rather than a single origin, to settle in Italy. Within this complex web of migration, the ethnic composition of ancient Italy was established—with groups such as the Etruscans, who maintained a distinctive language and culture, emerging, and groups such as the Latins, who were demographically dominant, rising to prominence.

In conclusion, the Late Bronze Age collapse was a decisive turning point in the formation of the ancient peoples of Italy. The period of turmoil and collapse was, paradoxically, the gestational period of new peoples, and in this time and space where destruction and creation intersected, the Italian peninsula underwent an anthropological reorganization transitioning from late prehistory to historical times. The traces inscribed in myth, genes, and culture become clues for us to reconstruct the transformation of that time in three dimensions. Through the convergent research of modern science and the humanities, we will be able to elucidate ever more clearly how the great human upheaval at the end of the Bronze Age of the distant past was imprinted on the origins of the human groups that have continued to this day.

The above text was written with the help of ChatGPT. I organized the argument that the upheaval at the end of the Bronze Age likely influenced the formation of the ancient peoples of Italy, along with the archaeological, mythical, genetic, and textual evidence supporting it, presented this to GPT, and asked it to write a paper. Unfortunately, GPT failed to synthesize all of the arguments I had prepared (such as the tradition of King Priam’s expedition to Italy). This is probably because of the output limit of about 10 A4 pages. But from a macroscopic perspective, it conveyed the core thesis well. At least for me to read and enjoy on my own, it seems lacking in nothing. I look forward to the further development of AI in the future.
