The Russian-Circassian War was the period of hostilities between the Russian Empire and the inhabitants of Circassia during the Russian invasion and occupation of the Circassian region. Circassia was a region in Caucasia which consisted of the coastline and most of the interior of the current territory of Krasnodar Krai and Adygea. The historical region, now mainly North Ossetia-Alania, was named after the traditional inhabitants, the Circassians, Adyghe or Adiga, along with a number of smaller ethnic groups and tribes. The Russian-Circassian conflict began with the initial arrival of Russian occupation forces in 1763, and ended with the signing of several Russian loyalty oaths by Circassian leaders on June 2, 1864 (May 21, O.S.). While the Russian-Circassian War began as an isolated conflict, Russian expansion through the entire region soon brought it into conflict with a number of other nations in what later became known as the Caucasian War, and of which the Russian-Circassian War became a part. Both came to an end with the signing of the loyalty oaths to Russia, and with the total occupation of the region by Russian forces, which involved the mass migration of millions of indigenous Circassians to areas of the Ottoman Empire (modern Turkey, Syria, Lebanon, Jordan and Kosovo), with some Circassian historians citing that up to 4,000,000 civilians perished during the exodus.
