During the decline and dissolution of the Ottoman Empire, Muslim (including Ottoman Turks, Albanians, Bosniaks, Circassians, Serb Muslims, Greek Muslims, Muslim Roma, Pomaks) inhabitants living in territories previously under Ottoman control, often found themselves as a persecuted minority after borders were re-drawn. These populations were subject to genocide, expropriation, massacres, and ethnic cleansing.

The 19th century saw the rise of nationalism in the Balkans coincident with the decline of Ottoman power, which resulted in the establishment of an independent Greece, Serbia and Bulgaria and Romania. At the same time, the Russian Empire expanded into previously Ottoman-ruled or Ottoman-allied regions of the Caucasus and the Black Sea region. These conflicts created large numbers of Muslim refugees. Persecutions of Muslims resumed during World War I by the invading Russian troops in the east and during the Turkish War of Independence in the west, east, and south of Anatolia by Greeks and Armenians. After the Greco-Turkish War, a population exchange between Greece and Turkey took place, and most Muslims of Greece left. During these times many Muslim refugees, called Muhacir, settled in Turkey.
