What Can and Cannot Be Said
There is no proof that a Greek army besieged Troy for ten years to recover Helen. No document from the Bronze Age mentions such a war, and no excavation has found a layer that tells that story. The Iliad is a poem composed and performed long after any events it might remember, and its details are poetic.
That said, the opposite claim, that nothing at all lies behind the legend, is also hard to defend. A real city stood at the site of Hisarlik in northwest Turkey. It was rich, fortified and in contact with the Aegean world. Hittite records from the same period mention a western Anatolian state whose name looks like a form of “Ilios”, and they mention trouble with a people who may be Greeks. A Late Bronze Age conflict of some kind in that region is plausible. A conflict that matches Homer is not demonstrated.
The City at Hisarlik
The mound of Hisarlik, near the Dardanelles, contains many settlement layers, stacked over about three thousand years. Archaeologists number them Troy I to Troy IX. The layers relevant to the legend belong to the Late Bronze Age, roughly the sixteenth to twelfth centuries BCE.
Troy VI, the great citadel of the middle of that period, had massive stone walls and substantial buildings. It seems to have ended around 1300 BCE. Some excavators proposed an earthquake, though the cause is debated. The settlement that followed, called Troy VIIa, was smaller and more crowded, and it ended in a destruction by fire at some point around 1200 BCE or a little later. Some scholars therefore prefer VIIa as the “Homeric” Troy, others VI, and others argue neither city can be matched to the poem.
Later excavations, particularly those led by Manfred Korfmann from the late 1980s, argued that Troy was larger than previously thought, with a lower town beyond the citadel and defensive ditches. The size of that lower town has been challenged by other archaeologists, and the argument remains active. Imported Mycenaean pottery at the site shows trade or contact with the Greek mainland, which is what one would expect of any harbour town on the route to the Black Sea. Work continues, and the Hisarlik excavations have repeatedly revised earlier pictures of the site.
A destruction layer by itself proves little. Cities burned for many reasons, including accident, earthquake, internal conflict and raids. Dating such layers also depends on pottery sequences and on radiocarbon dating, both of which give ranges, not single years.
The Hittite Evidence: Wilusa and Ahhiyawa
The most interesting outside evidence comes from clay tablets in the archives of the Hittite capital, Hattusa, in central Anatolia. After the Hittite decipherment in the early twentieth century, scholars found references to western lands that the Hittite kingdom either ruled or contested.
Wilusa is the name of one of these western states. A treaty between the Hittite king, usually identified as Muwatalli II in the thirteenth century BCE, and a ruler called Alaksandu of Wilusa is preserved. Other letters mention Wilusa as a region that had been the subject of conflict. Linguists note that Wilusa is close to the early Greek form of “Ilios”, the other name for Troy, and that Alaksandu resembles Alexandros, the second name of Paris in Homer. These similarities are suggestive, and many scholars accept them, though they are not proof of identity.
The Hittite texts also refer to Ahhiyawa, a kingdom overseas or on the western coast, whose ruler is addressed in one letter as an equal, a “brother”. Ahhiyawa is widely, though not unanimously, taken to be the Mycenaean Greeks, the Achaeans of Homer. The texts describe tensions over western Anatolia, including a local adventurer named Piyamaradu, who raided Wilusa and had contacts with Ahhiyawa. The city of Millawanda, probably Miletus, appears as a place under Ahhiyawan influence.
This is real evidence of Greek and Anatolian rivalry in the thirteenth century BCE. It is not a record of a Greek expedition against Wilusa, and none of the tablets describes a siege, a stolen queen or a leader like Agamemnon. In the Hittite sources, the matter appears to be a diplomatic dispute, not a legendary war.
A Luwian-inscribed bronze seal found at Troy in the 1990s suggests that people at the site used Luwian, a language related to Hittite. This is consistent with a city whose culture looked toward Anatolia as much as toward the Aegean.
A Wider Collapse
Around 1200 BCE, much of the eastern Mediterranean world was shaken. Mycenaean palaces were destroyed or abandoned, the Hittite state collapsed, and trade networks were disrupted. Causes are debated and probably included several factors such as drought, earthquakes, migrations and internal strife. Trade had flourished earlier, as the Uluburun shipwreck and its cargo show.
If Troy VIIa was destroyed in that period, as it appears to have been, its fall belongs to a time of widespread disaster. A later poet might have drawn a story of one great siege from the memory of many violent changes. That is an idea, not a finding.
What the Poems Do Preserve
The Iliad contains some features that seem to reach back to the Bronze Age, such as boar’s-tusk helmets and the heavy body-shield, and a catalogue of Greek regions that partly resembles Mycenaean centres. It also includes features from later periods, such as the practice of cremating the dead, which differs from standard Mycenaean burial. Scholars generally conclude that the poems blend memory from many centuries. The wider Homeric historicity debate asks how much of the poems can be trusted as history.
Where the Evidence Stops
The detailed story, with a coalition under Agamemnon, a decade of siege and a wooden horse, is not documented by any source outside the epic tradition. New finds or readings may refine the picture, but at present the evidence supports a possible real background, not a historical Trojan War as Homer tells it.
