Chukchi people
During the first half of the 17th century, Russians reached the far north-east. In 1641, the first reference to Chukchi people was made by the Cossacks. In 1649, Russian explorer Semyon Dezhnyov explored the far north-eastern coast and established winter quarters on the upstream portion of the Anadyr River that became the fortified settlement of Anadyrsk. Dezhnyov tried to subjugate the Chukchi and exact tribute during the next ten years, but was mostly unsuccessful. Eventually the fort was abandoned, because of the harsh northern conditions and lack of game animals for food.
