Did The Trojan War Really Happen?

I got a lot of this information from Archaeology Archive (http://archive.archaeology.org/0405/etc/troy.html)
The article may be from 2004 but it's written by an actual archaeologist and it's pretty informative. 

Excavation of Troy

Was there ever a Trojan War? How could we really know? I mean, it was said to have happened over 3000 years ago and with all the Greek gods involved, not to mention a practically immortal warrior running around, you begin to wonder how could this possibly have happened?

Manfred Korfmann, director of the excavations, is excavating at a site in northwestern Turkey that appears to have been a city that began as an Early Bronze Age citadel in the third millennium BCE. Korfmann says the city appears to have been destroyed in 1180 BCE by a lost war. This evidence corresponds with Homer's Iliad. It appears that this city was, by the standards of this region at that time, very large, and most certainly very important in controlling access from the Mediterranean to the Black Sea, again matching up with Homer's epic.

Okay, so Troy did exist but did the infamous Trojan War really happen? Manfred Korfmann says Troy was  evidently attacked repeatedly and had to defend itself again and again, as indicated by repairs undertaken to the citadel's fortifications and efforts to enlarge and strengthen them. Korfmann admits he does not know if any of these apparent attacks occurred in the Trojan War but he believes they very well could have been. "If someone came up to me at the excavation one day and expressed his or her belief that the Trojan War did indeed happen here, my response as an archaeologist working at Troy would be: Why not?"


To this day, no one knows if the Trojan Horse was actually a cunning strategy used by the Greeks or just an embellishment by Homer to spice up his epic poem.

As for all the Greek gods and demigods, they were added to the picture later in Greek Mythology.
