Russian colonization of North America

Russian expansion eastward began in 1552, and in 1639 Russian explorers reached the Pacific Ocean. In 1725, Emperor Peter the Great ordered navigator Vitus Bering to explore the North Pacific for potential colonization. The Russians were primarily interested in the abundance of fur-bearing mammals on Alaska's coast, as stocks had been depleted by overhunting in Siberia. Bering's first voyage was foiled by thick fog and ice, but in 1741 a second voyage by Bering and Aleksei Chirikov made sight of the North American mainland. Bering claimed the Alaskan country for the Russian Empire. Russia later confirmed its rule over the territory with the Ukase of 1799 which established the southern border of Russian America along the 55th parallel north.
