Why the Trojan War take place?

Answer 1

Oral epics such as those recorded by Homer typically have their roots in real events. Often archaeologists can eventually corroborate some of the details of oral traditions with archaeological finds. This is the case with Troy. Evidence over the past century suggests that ancient Troy was located at the current day site of Hisarlik in Turkey.
