The Cossack emigration consisted largely of relatively young men who had served, and retreated with, the White armies. Although hostile to communism, the Cossack émigrés remained broadly divided over whether their people should pursue a separatist course to acquire independence or retain their close ties with a future post-Soviet Russia. Many quickly became disillusioned with life abroad. Throughout the 1920s, thousands of exiled Cossacks voluntarily returned to Russia through repatriation efforts sponsored by France, the League of Nations, and even the Soviet Union.
