The treaty, signed during Lousanna Peace negotiations, regarding the exchange of the muslims living in Greece and Greeks living in Turkey resulted in important developments for the both countries. It should be stressed that compulsory exchanging of the people (renoving them from their own lands where they grew up) is a real cruelty for them but it had to be carried out in the areas where Greece implemented its policy because the people were under pressure by Greece, which wanted to nationalize its newly-captured areas. After it implemented the same nationalization policy when invading the West Anatolia, the hostility occured between both nations and living together in the same land became impossible. Meanwhile, both Turkey and Greece were sending minorities living in their lands to other countries and the two countries were getting of the minority problem and getting the chance of being a country of one nation. Although they first encountered adaptation problems in terms of economic and social aspects, compulsory migration started making the two countries become national. Niğde was one of the cities where that compulsory migration took place in significant numbers. Niğde,whose population had had 30% non-muslim minority before the migration, became a Turkish city with % 100 rate.
