The Russians were also launching wars and slaughters against the Koraks in 1744 and 1753-4. After the Russians tried to force the natives to convert to Christianity, the different native peoples like the Koraks, Chukchis, Itelmens, and Yukagirs all united to drive the Russians out of their land in the 1740s. The genocide by the Russian Cossacks devastated the native peoples of Kamchatka and exterminated much of their population. In addition to committing genocide the Cossacks also devastated the wildlife by slaughtering massive amounts of animals for fur. 90% of the Kamchadals and half of the Vogules were killed from the eighteenth to nineteenth centuries and the rapid genocide of the indigenous population led to entire ethnic groups being entirely wiped out, with around 12 exterminated groups which could be named by Nikolai Iadrintsev as of 1882. Much of the slaughter was brought on by the fur trade.
