The Iroquois Wars, also known as the Beaver Wars and the French and Iroquois Wars, were a series of 17th-century conflicts involving the Haudenosaunee Confederacy (also known as the Iroquois or Five Nations, then including the Mohawk, Oneida, Onondaga, Cayuga and Seneca), numerous other First Nations, and French colonial forces. The origins of the wars lay in the competitive fur trade. In about 1640, the Haudenosaunee began a campaign to increase their territorial holdings and access to animals like beaver and deer. Hostilities continued until 1701, when the Haudenosaunee agreed to a peace treaty with the French. The wars represent the intense struggle for control over resources in the early colonial period and resulted in the permanent dispersal or destruction of several First Nations in the Eastern Woodlands.
