The annexation of Western Armenia

What is described by some as the Armenian genocide refers to the massacres and supposed forced deportation of hundreds of thousands of Armenians during the first world war.
A series of Muslim Arab armies conquered the area from the middle ages culminating in the Ottomon dynasty which ruled Eastern Armenia. Western Armenia was part of the Russian empire from 1828.
Russia entered the first world war against Germany in 1914.
An estimated million and a half, said to be mainly Christian Armenians were killed by Ottoman forces who backed Germany, from about 1914-1917. Many are reported to have had their properties consficated and were marched away to various areas. There were accusations of atrocities.
Present day Armenians are believed to be local to the highlands of Armenia, then Eastern Armenia. Muslim Kurds in present day Armenia are recognised as Armenian and assimilated. Conversion to Islam in the middle east is thought to have been mandatory. There may be around 37,000 Kurdish people living in Armenia according to some statistics, and an estimated 30-40 million worldwide, fourteen million living in what is sometimes known as Kurdish Turkey and used to be western Armenia.
