Circassian nationalism is the desire among Circassians worldwide to preserve their genes, heritage and culture, save their language from extinction, raise awareness about the Circassian genocide, return to Circassia and establish a completely autonomous or independent Circassian state in its pre-Russian invasion borders.

The Circassian diaspora refers to ethnic Circassian people around the world who live outside their homeland Circassia. The majority of the Circassians live in the diaspora, as their ancestors were settled during the resettlement of the Circassian population, especially during the late nineteenth and early twentieth century. From 1763 to 1864, the Circassians fought against the Russian Empire in the Russian-Circassian War, finally succumbing to a scorched-earth genocide campaign initiated between 1862 and 1864. Afterwards, large numbers of Circassians were exiled and deported to the Ottoman Empire and other nearby regions; others were resettled in Russia far from their home territories. Circassians live in more than fifty countries, besides the Republic of Adygea. Total population estimates differ: according to some sources, some two million live in Turkey, Jordan, Syria, and Iraq; other sources say between one and four million live in Turkey alone.
