Wilusa, the real Troy:

Was There a Trojan War?

by Manfred Korfmann. More at Project Troia.

So, there likely was a "Wilusan war", but almost
certainly no Helen of Troy, no Achilles, no Priamos.
And soon after the Aegean, Asia Minor and Middle East
were in turmoil. The Myceneans went into terminal
decline, the Sea Peoples attacked and the Hittite
Empire fell between 1200-1190 BCE, soon Egypt was in
decline and in effect split in two after the death of
the last Ramesses (between 1085-1067 BCE). In Mesopotamia
the Assyrian Empire retreated to it´s heartland after
the reign of Tiglatpileser I(c.1115-1075 BCE). Babylon
and Elam first conquered each other and then went into
decline. The whole political, economical and cultural
landscape where the people of Wilusa had lived started
to disappear only decades after the fall of their town.
