For World War I, the relatively most reliable sources can be found for Anatolia, especially in relation to the Caucasus Campaign. There is a total number reached and reported by the Ottoman Empire at the end of 1916. On the basis of previous Ottoman census, the Turkish historian Kamer Kasim (Manchester University, PhD), arrives at the conclusion that the movements of refugees from the Caucasus war zone had reached 1.500.000 people who were relocated in the Mediterranean region and Central Anatolia under very difficult conditions.[1] Kamer Kasım's number or any other number on this issue has not been reported in western sources.
