The Fox Wars were two conflicts between the French and the Fox  Indians that occurred in the Great Lakes region  from 1712 to 1733. These territories are known today as the states of Michigan and Wisconsin in the United States. The Wars exemplified colonial warfare in the transitional space of New France, occurring within the complex system of alliances and enmities with native peoples and colonial plans for expansion. The Fox controlled the Fox River system. This river was vital for the fur trade between French Canada and the North American interior, because it allowed river travel from Green Bay in Lake Michigan to the Mississippi River. The French wanted the rights to use the river system to gain access to both the Mississippi and trade contacts with tribes to the west. The wars claimed thousands of lives and initiated a slave trade whereby Fox Indians were captured by native allies of New France and then sold as slaves to the French colonial population.:54 Indeed, alliances between the French and other native groups  as well as those between the Fox and other native groups  were an important aspect of the Wars, influencing every stage of the conflicts, including the causes, the fighting and the conclusion.:54 The First Fox War  began with inter-alliance violence and ended with the surrender of a large group of Fox and the subsequent peace deal.:63:169 As was custom, peace offerings required the exchange of goods and of prisoners to account for those who died in the conflict, acknowledging the importance of this exchange for establishing peace.:64 The Second Fox War  was far more destructive than the first, and ended with the near annihilation of the Fox population.:169
