The Haudenosaunee Confederacy, known as the Iroquois Confederacy, stands as one of the most influential and enduring political alliances in North American history. Rooted in the Great Law of Peace, this sophisticated system of governance shaped the trajectory of Indigenous diplomacy, warfare, and sovereignty. From their tactical military strategies and powerful negotiations with European settlers to their profound cultural contributions and lasting influence on global Indigenous movements, the Confederacy remains a beacon of resilience and leadership. This book explores their impact on democracy, land rights struggles, environmental stewardship, and cultural revitalization, revealing why the Haudenosaunee continue to shape Indigenous politics today.
