Kuban Cossacks
In 1828, the Danubian Sich ceased to exist after it was pardoned by Emperor Nicholas I, and under amnesty its members settled on the shores of the Northern Azov between Berdyansk and Mariupol, forming the Azov Cossack Host. Finally in 1862 they too migrated to the Kuban and merged with the Kuban Cossacks. The Kuban Cossacks served Russia's interests right up to the October Revolution, and their descendants are now undergoing active regeneration both culturally and militarily. The 30,000 descendants of those Cossacks who refused to return to Russia in 1828 still live in the Danube delta region of Ukraine and Romania, where they pursue the traditional Cossack lifestyle of hunting and fishing and are known as "Rusnaks".
