The founding of the Native American Iroquois Confederacy.
Hiawatha wanted peace, but a more powerful chief named Tadodaho opposed him. So he joined forces with a man called the Peacemaker and a woman named Jigonsaseh, who dreamed of uniting the five Haudenosaunee (Iroquois) nations under one Great Law of Peace.
After getting the Seneca to join the Great Law of Peace, Hiawatha came up with a plan to convince Tadodaho. But it took Jigonsaseh to confront him and make him become a true leader. Now united, the Five Nations created a participatory democracy rooted in the Peacemaker's ideals, one that still lives on today.
