Biberkriege
Beginning in 1609, the League engaged in the decades-long Beaver Wars against the French, their Huron allies, and other neighboring tribes, including the Petun, Erie, and Susquehannock. Trying to control access to game for the lucrative fur trade, they invaded the Algonquian peoples of the Atlantic coast (the Lenape or Delaware), the Anishinaabe of the boreal Canadian Shield region, and not infrequently the English colonies as well. During the Beaver Wars, they were said to have defeated and assimilated the Huron (1649), Petun (1650), the Neutral Nation (1651), Erie Tribe (1657), and Susquehannock (1680). The traditional view is that these wars were a way to control the lucrative fur trade to purchase European goods on which they had become dependent.
