The Iroquois confederacy was formed to?

The Iroquois Confederacy, also known as the Haudenosaunee or Six Nations, was formed to promote unity and cooperation among its member tribes—initially the Mohawk, Oneida, Onondaga, Cayuga, and Seneca, later joined by the Tuscarora. Established to strengthen their collective defense against external threats, particularly from European colonizers and rival tribes, the Confederacy also aimed to facilitate trade and resolve intertribal disputes through a shared governing council. This sophisticated political alliance exemplified early democratic principles and significantly influenced the development of governance in North America.
