Overview

The Haudenosaunee ("People of the Longhouse"), known to Europeans as the Iroquois and to the French as the League of the Iroquois, were the most powerful Indigenous confederacy of northeastern North America. Founded — by tradition — when the prophet-statesman Deganawidah (the Great Peacemaker) and his spokesman Hiawatha persuaded five warring nations to bury their weapons under the Tree of Peace, the confederacy was governed by the Great Law of Peace (Kaianere'kó:wa), an oral constitution of remarkable sophistication. (Its founding date is disputed: oral tradition and some scholars argue for as early as c. 1142, while others place it around 1450; the source table uses 1450.)

History

The original Five Nations, arranged west to east, were the Seneca, Cayuga, Onondaga, Oneida, and Mohawk; the Tuscarora joined in 1722 after fleeing war in the Carolinas, making it the Six Nations. Governance rested on a Grand Council of 50 sachems (hoyenah) meeting at the central fire at Onondaga, chosen and removable by the clan mothers of a matrilineal society — a system whose consensus decision-making and division of powers some scholars (controversially) argue influenced the U.S. founders. Society was organized around longhouses, clans, and the "Three Sisters" agriculture (maize, beans, squash).

Decline and legacy

The confederacy dominated regional geopolitics for over two centuries. In the 17th-century Beaver Wars, the Haudenosaunee (armed by Dutch and English traders) shattered rival nations (Huron/Wendat, Erie, Neutral) to control the fur trade. They played France and Britain against each other, generally allying with the British against New France. The confederacy's unity finally broke during the American Revolution (1775–1783): most nations (led by the Mohawk under Joseph Brant/Thayendanegea) sided with Britain, while the Oneida and Tuscarora largely backed the rebels — a civil war within the League. The Continental Army's Sullivan Expedition (1779) devastated Iroquois villages, and the Treaty of Paris (1783) abandoned Britain's Native allies. The confederacy split, with many Mohawk and others resettling in Canada (Grand River/Six Nations of the Grand River and Tyendinaga), while others remained in New York. The Haudenosaunee endure today as living nations on both sides of the border, with the Grand Council still seated at Onondaga.
