The 1794 Treaty of Canandaigua is one of the most important treaties in the history of the Haudenosaunee. It guarantees the rights of sovereignty for the Six Nations, while at the same time making huge land concessions. It is a treaty that has faced numerous violations throughout it's 200+ year existence. However, it is still one of the oldest unbroken agreements in United States history.
