There are a number of scientific approaches of understanding the concept of Genocide. Some of them may spread a light on understanding the impact of Genocide on the identity of both the victim and the murderer. For instance among such approaches are AleidaAssmann’s discussions of collective memory, Gregory H. Stanton’s suggestions of the genocidal process, the concept of cultural trauma of Jeffrey Alexander, etc. The Armenian Genocide is not an exception. Nevertheless the Armenian Genocide has its own features and characteristics. Moreover it is distinguished from other cases by its results and effects on the society. To be precise we come across to a complicated phenomenon which is typical for the Armenian case. On the one hand it has created dual Armenian identity via Diaspora. On the other hand within the memory of the Genocide it has constructed the images of victim and the image of enemy. Both of these factors are highly connected to nationalism and nationalistic behavior.
