الكوبان
Black Sea Cossack Host (), also known as Chernomoriya (), was a Cossack host of the Russian Empire created in 1787 in southern Ukraine from former Zaporozhian Cossacks. In the 1790s, the host was re-settled to the Kuban River. It comprised the Caucasus Fortified Defence Line from the mouth of the Kuban River to the mouth of the Bolshaya Laba River.
