Muhacir, Macırlar, or Muhajir, is a term used to refers to an estimated 10 million Ottoman Muslim citizens (including Turks, Albanians, Bosniaks, Circassians, Crimean Tatars, and Pomaks) who emigrated to Anatolia from the late 18th century until the end of the 20th century.Some five to seven million Muslim migrants from hostile regions arrived in Ottoman Anatolia from 1783 to 1914; the influx of migration during the late 19th century and early 20th century was due to the loss of almost all Ottoman territory during the Balkan War of 1912-13 and World War I.
