Circassia (Circassian: Адыгэ Хэку, Adyge Kheku; Russian: Черкесия, Cherkesiya), officially the Republic of Circassia, is a republic of the Soviet Union. Initially divided between several divisions within the Russian Federation, the region would become united in the Saint Petersburg Compromise of 1997, but would not become its current size (or a republic) until the Black Sea Compromise of 1999. Circassia contains a mixed population of Russians and Circassians, in which the titular and native Circassians currently make up less than a third of the population.
