In page Chukchi people:

"

In 1742, the government at Saint Petersburg ordered another war in which the Chukchi and Koryak were to be "totally extirpated". The war (1744–47) was conducted with similar brutality and ended when Pavlutsky was killed in March 1747.[3] It is said that the Chukchi kept his head as a trophy for a number of years. The Russians waged war again in the 1750s, but a part of Chukchi people did survive this extermination plans on the very far North East (see on the right a map for population territories during the extermination activity by the Russian Empire).[citation needed]
