The first migrations from Bulgaria to our country, which began with the Ottoman-Russian wars (1806-1812), continued during the Republican period. Following the increase in pressure exerted by Bulgaria on the Turks since 1923, Turks living here began to migrate to their country of origin (Sarınay, 2011: 357). In order to regulate these migratory waves that occurred in the first years of the Republic, a Turkish-Bulgarian residence agreement was signed in Ankara on October 18, 1925 (Soysal, 1983). According to this agreement; Voluntary migration of Turks living in Bulgaria would not be prevented, immigrants would be able to take with them their movable property and animals and they would also be able to freely sell their real estate. With this agreement, migration from Bulgaria to Turkey has become systematic, with an average of 10,000 people migrating each year. The number of Bulgarian immigrants to Turkey between 1923 and 1933 was 101,507, and during the dictatorship of King Boris in Bulgaria starting in 1934, the annual rate of immigration to Turkey exceeded 20,000 in 1935 and 1938 (Öksüz , 2000: 178-179). ). In 1939, the number of immigrants reached 198,688 people (Şimşir, 2009: 229). Due to intense immigration from the Balkans since the 1930s, Turkey enacted the Settlement Law on June 14, 1934 to regulate the acceptance and settlement of immigrants. . During World War II and the years following the war, immigration to Turkey declined significantly due to the fact that Bulgaria largely banned foreign travel and did not issue passports to Turks for immigration . In fact, 21,353 Bulgarian Turks immigrated to Türkiye between 1940 and 1949 (Şimşir, 2009: 230). With the communist regime coming to power in Bulgaria in 1944, the Bulgarian Communist Party (BKP) gained the support of the people. ..... Bilgi Yayınevi. Sarınay, Y. (2011).
