The 1833 Treaty of Chicago struck an agreement between the United States government that required the Chippewa Odawa, and Potawatomi tribes cede to the United States government their 5,000,000 acres (2,000,000 ha) of land (including reservations) in Illinois, the Wisconsin Territory, and the Michigan Territory and to move west of the Mississippi River. In return, the tribes were given promises of various cash payments and tracts of land west of the Mississippi River. The treaty was one of the removal treaties to come after the passage of the Indian Removal Act. This was the second treaty referred to as the "Treaty of Chicago", after the 1821 Treaty of Chicago.
