Koryak

The Koryaks lived north of Kamchatka and along the Bering Sea, divided between coastal fishing villages and inland reindeer-herding groups. Russian Cossack Vladimir Atlasov recorded their name during his Kamchatka campaigns in the 1690s. Warfare with Cossacks and a smallpox epidemic in 1769–1770 sharply reduced the Koryak population.
