Ans. The Iroquois Confederacy, also known as the Haudenosaunee Confederacy, was a political and cultural alliance of six Native American tribes - Mohawk, Oneida, Onondaga, Cayuga, Seneca, and Tuscarora. It was formed under the leadership of Hiawatha and the Great Peacemaker to promote peace, unity, and mutual cooperation among the tribes. The Iroquois Confederacy played a significant role in the history of the Native Americans, as it served as a model for democratic governance and influenced the formation of the United States' political system.
