There are four treaties of Buffalo Creek, named for the Buffalo River in New York. The Second Treaty of Buffalo Creek, also known as the Treaty with the New York Indians, 1838, was signed on January 15, 1838 (proclaimed on April 4, 1840) between the Seneca Nation, Mohawk nation, Cayuga nation, Oneida Indian Nation, Onondaga (tribe), Tuscarora (tribe) and the United States. It covered land sales of tribal reservations under the U.S. Indian Removal program, by which they planned to move most eastern tribes to Kansas Territory west of the Mississippi River.
Treaty of Buffalo Creek-January 15, 1838-Article I-The New York Indians also agreed to "cede and relinquish to the United States all their right, title, and interest to the lands secured to them at Green Bay by the Menominee Treaty of 1831, excepting the following tract, on which a part of the New York Indians now reside." The tract was eight by twelve miles consisting of 65, 436 acres or equal to 100 acres for each of the 654 Oneida that were presently living there. This established the original boundaries of the Oneida Reservation of Wisconsin.
