On September 24-25 2005, a conference entitled "Ottoman Armenians During the Decline of the Empire: Issues of Scientific Responsibility and Democracy" was held at Bilgi University in Istanbul after two previous attempts which were blocked by the Turkish government. The goal of the conference was to call into question the official Turkish account of events. It was the first time this subject was ever discussed so openly in Turkey. Hrant Dink was one of the organisers.
I was there as a journalist from Yerkir Media TV. Here is my coverage of the event (in Armenian).
