Question

which treaty forced the iroquois to give up large portions of land to the newly independent united states?
treaty of canandaigua
treaty of ft. stanwix
treaty of greenville
treaty of ft. wayne

Explanation:

The Treaty of Fort Stanwix (1784) was the first treaty between the newly independent United States and the Iroquois Confederacy. It forced the Iroquois to cede large portions of their land in New York and Pennsylvania to the U.S. government. The Treaty of Canandaigua (1794) was more about establishing a peaceful relationship and some land - related provisions but not the large - scale forced cession right after independence. The Treaty of Greenville (1795) was with the Western Confederacy (not the Iroquois) and the Treaty of Fort Wayne (1803) was much later and also not related to the immediate post - independence land cession from the Iroquois.

Answer:

Treaty of Ft. Stanwix
