Hiawatha was a legendary leader and co-founder of the Iroquois Confederacy, an alliance of five (later six) Native American nations. He played a crucial role in promoting peace among warring tribes and is often associated with the formation of the Great Law of Peace, which established principles for governance and social order within the Confederacy. Hiawatha's teachings emphasized unity, cooperation, and collective decision-making, helping to create a political structure that significantly influenced the social and political landscape of Native American tribes.
