The Circassian diaspora are ethnic Circassians around the world who were driven from Circassia during the late nineteenth and early twentieth century. From 1763 to 1864, the Circassians fought against the Russian Empire in the Russian-Circassian War which ended in a genocide campaign initiated between 1862 and 1864. Large numbers of Circassians were exiled and deported to the Ottoman Empire and nearby regions; others were resettled in Russia far from their homeland. Circassians live in more than fifty countries, besides the Republic of Adygea. Total population estimates differ: according to some sources, some two million Circassians live in Turkey, Jordan, Syria, and Iraq; other sources say between one and four million live in Turkey alone.
