This study deals with the political, commercial, cultural and sportive relations between Turkey and Yugoslavia during the Democratic Party Period in the Republic of Turkey between the years 1950-1960 and the issue of migration. The Balkan lands, which have a special importance in the foreign policy understanding of the Democratic Party, which came to power in Turkey in 1950, have an important issue in terms of regional alliance. It is noteworthy that Yugoslavia, which has the largest piece of land in this region, is home to more than one nation. Turkey, on the other hand, developed its relations with Yugoslavia through the Balkan Pact and the Balkan Alliance and made mutual visits with state officials. As a result of the developing relations, although the two states were at different poles ideologically, relations in the political, commercial, cultural and sports fields continued increasingly. While Turkey and Yugoslavia were improving their relations, on the other hand, problems arose between the two states due to the issue of immigration. The assimilation policy implemented by Yugoslavia against the Turks living in the region and the situation of forcing them to migrate have caused immigrants to come to Turkey for years. Turkey, on the other hand, did not turn these immigrants back and systematically took them into their lands. After the immigrants were taken, they were settled at certain points and they were taken into business life.
