dat 1910 map doe
Get da feck outta hea' with dat.
This is 1980, to start.
Because modern maps are a rarity here's a few quotes from wikipedia:
Armenians in Turkey have an estimated population of 40,000 (1995) to 70,000. Most are concentrated around Istanbul. The Armenians support their own newspapers and schools. The majority belong to the Armenian Apostolic faith, with smaller numbers of Armenian Catholics and Armenian Evangelicals.In 1995 there were only between 40,000 to 70,000 Armenians in Turkey, and most of them, according to that quote, were around Istanbul. This means there wouldn't even be that many Armenians left in Eastern Turkey, so they wouldn't be a majority there in PoW like you claim. Another quote:
Until the Armenian Genocide of 1915, most of the Armenian population of Turkey (then the Ottoman Empire) lived in the eastern parts of the country that Armenians call Western Armenia (roughly corresponding to the modern Eastern Anatolia Region).Armenians, according to that, left Eastern Turkey after the genocide (or were killed).
