The North American fur trade began around 1500 off the coast of Newfoundland and became one of the most powerful industries in US history. In Minnesota country, the Dakota and the Ojibwe traded in alliance with the French from the 1600s until the 1730s, when Ojibwe warriors began to drive the Dakota from their homes in the Mississippi Headwaters region. Afterward, the Dakota continued trading in the south while Montreal traders and their Ojibwe allies established a network of trading posts in the north. For the next 120 years, the fur trade dominated the region’s economy and contributed to the development of a unique multicultural society.
