The Iroquois Great Law of Peace is a constitution-like framework that established a system of governance for the Iroquois Confederacy, promoting unity, peace, and cooperation among its member nations. This law emphasized collective decision-making and was instrumental in maintaining harmony within the confederacy, which comprised several tribes including the Mohawk, Oneida, Onondaga, Cayuga, Seneca, and later the Tuscarora. The Great Law of Peace showcases the political sophistication of Native American cultures in North America and their methods for resolving conflict and promoting stability.
