The Two Row Wampum Treaty

The Two Row Wampum Treaty, also known as Guswenta or Kaswentha and as the Tawagonshi Agreement of 1613 or the Tawagonshi Treaty, is a mutual treaty agreement, made in 1613 between representatives of the Five Nations of the Iroquois (Haudenosaunee) and representatives of the Dutch government in what is now upstate New York. The agreement is considered by the Haudenosaunee to be the basis of all of their subsequent treaties with European and North American governments, and the citizens of those nations, including the Covenant Chain treaty with the British in 1677 and the Treaty of Canandaigua with the United States in 1794.
