Muhacirs overwhelmingly self-identified as Muslims and their numbers are estimated in the millions. The refugees from Macedonia, Bulgaria, and parts of Serbia had primarily Anatolian Turkish background. Other backgrounds included Albanians, Bosniaks, Chechens, Circassians, Crimean Tatars, Pomaks, Macedonian Muslims, Greek Muslims, Serb Muslims, Georgian Muslims, Ossetian Muslims and Muslim Roma.

They immigrated to modern-day Turkey, mostly in the 19th and early 20th centuries to escape the persecution of Ottoman Muslims by Christians in territories formerly controlled by the Ottoman Empire. Further migration from Bulgaria occurred from 1940 to 1990. Up to a third of the modern-day population of Turkey may have ancestry from these Turkish and other Muslim migrants.
