How did the loss of Armenian communities in Turkey after 1915 affect Armenian dialects?

Before 1915, there were approximately 50 known dialects of the Armenian language. The events of 1915, which involved the massacre and forced exodus of the Armenian population in Turkey, resulted in a drastic reduction of these communities. This catastrophic loss led to the disappearance or severe decline of many of these distinct, sometimes mutually unintelligible, dialects.1

The destruction of these populations fundamentally altered the linguistic landscape, as the speakers who maintained these regional varieties were dispersed or killed, severing the continuity of these oral traditions. Today, the modern language is primarily represented by two standardized literary varieties: Western Armenian, which is used by the diaspora and historically based on the dialect of Istanbul, and Eastern Armenian, which is prevalent in Armenia and surrounding regions.12
