In North America, there was significant tension between New France and the northern English colonies, which had in 1686 been united in the Dominion of New England. New England and the Iroquois Confederacy fought New France and the Wabanaki Confederacy. The Iroquois dominated the economically important Great Lakes fur trade and had been in conflict with New France since 1680. At the urging of New England, the Iroquois interrupted the trade between New France and the western tribes. In retaliation, New France raided Seneca lands of western New York. In turn, New England supported the Iroquois in attacking New France, which they did by raiding Lachine.
