The Maritime Fur Trade was a ship-based fur trade system that focused on acquiring furs of sea otters and other animals from the indigenous peoples of the Pacific Northwest Coast and natives of Alaska. The furs were mostly sold in China in exchange for tea, silks, porcelain, and other Chinese goods, which were then sold in Europe and the United States. The maritime fur trade was pioneered by the Russians, working east from Kamchatka along the Aleutian Islands to the southern coast of Alaska. British and Americans entered during the 1780s, focusing on what is now the coast of British Columbia. The trade boomed around the turn of the 19th century. A long period of decline began in the 1810s. As the sea otter population was depleted, the maritime fur trade diversified and transformed, tapping new markets and commodities while continuing to focus on the Northwest Coast and China. It lasted until the middle to late 19th century. Russians controlled most of the coast of what is now Alaska during the entire era. The coast south of Alaska saw fierce competition between, and among, British and American trading vessels. The British were the first to operate in the southern sector, but were unable to compete against the Americans who dominated from the 1790s to the 1830s. The British Hudson's Bay Company entered the coast trade in the 1820s with the intention of driving the Americans away. This was accomplished by about 1840. In its late period the maritime fur trade was largely conducted by the British Hudson's Bay Company and the Russian-American Company. The maritime fur trade brought the Pacific Northwest coast into a vast, new international trade network, centered on the north Pacific Ocean, global in scope, and based on capitalism but not, for the most part, on colonialism. A triangular trade network emerged linking the Pacific Northwest coast, China, the Hawaiian Islands, Britain, and the United States. The trade had a major effect on the indigenous people of the Pacific Northwest coast, especially the Aleut, Tlingit, Haida, Nuu-chah-nulth, and Chinook peoples. There was a rapid increase of wealth among the Northwest Coast natives, along with increased warfare, potlatching, slaving, depopulation due to epidemic disease, and enhanced importance of totems and traditional nobility crests. The indigenous culture was not overwhelmed however but rather flourished, while simultaneously undergoing rapid change. The use of Chinook Jargon arose during the maritime fur trading era and remains a distinctive aspect of Pacific Northwest culture. The most profitable furs were those of sea otters, especially the northern sea otter. After the northern sea otter was hunted to local extinction, maritime fur traders shifted to California until the southern sea otter was likewise nearly extinct. The British and American maritime fur traders took their furs to the Chinese port of Canton, where they worked within the established Canton System.
