By the time of Russian colonization in the 17th century, the Yukaghir tribal groups occupied territories from the Lena River to the mouth of the Anadyr River. The number of the Yukaghirs decreased between the 17th and 19th centuries due to epidemics, internecine wars and Tsarist colonial policy which may have included genocide against the sedentary hunter-fisher Anaouls. Some of the Yukaghirs have assimilated with the Yakuts, Evens, and Russians.
