The Iroquois and Algonquin conflict refers to a series of battles and territorial disputes between two major Native American groups in the northeastern region of North America during the 17th century. The conflicts were rooted in competition for resources, trade routes, and control of land, which were further exacerbated by European colonization efforts. This rivalry played a significant role in shaping alliances and political dynamics among Indigenous peoples and influenced the formation of the Iroquois Confederacy.
