Yukaghir
The Yukaghirs were hunting and fishing communities spread from the Lena to the Anadyr in northeastern Siberia when Russians arrived in the seventeenth century. In 1638 a Russian detachment campaigned against Yukaghirs on the Indigirka. Epidemics, warfare and tsarist colonial policies reduced their numbers, while some Yukaghirs were absorbed by neighbouring Sakha, Evens and Russians.
