The Russian colonization of the Americas covers the period from 1732 to 1867, when the Russian Empire laid claim to northern Pacific Coast territories in the Americas. Russian colonial possessions in the Americas are collectively known as Russian 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.
Russian promyshlenniki (trappers and hunters) quickly developed the maritime fur trade, which instigated several conflicts between the Aleuts and Russians in the 1760s. The fur trade proved to be a lucrative enterprise, capturing the attention of other European nations. In response to potential competitors, the Russians extended their claims eastward from the Commander Islands to the shores of Alaska. In 1784, with encouragement from Empress Catherine the Great, explorer Grigory Shelekhov founded Russia's first permanent settlement in Alaska at Three Saints Bay. Ten years later, the first group of Orthodox Christian missionaries began to arrive, evangelizing thousands of Indians, many of whose descendants continue to maintain the religion. By the late 1780s, trade relations had opened with the Tlingits, and in 1799 the Russian-American Company (RAC) was formed in order to monopolize the fur trade, also serving as an imperialist vehicle for the Russification of Alaska Natives.
