The 1833 Treaty of Chicago was negotiated approximately three years after the United States government ratified the Indian Removal Act. This treaty represented part of a broader pattern of removal agreements that followed the passage of this landmark legislation. The negotiation occurred during a period when the federal government was actively pursuing the relocation of Native American tribes from their traditional lands east of the Mississippi River.
The treaty was an agreement between the United States government and three tribes: the Chippewa, Odawa, and Potawatomi. These tribes were required to cede 5,000,000 acres of land—including reservations—located in Illinois and the Michigan Territory, which at that time included Wisconsin and part of Minnesota. In exchange for this massive land cession, the tribes received promises of cash payments and tracts of land west of the Mississippi River. The treaty represented one of many removal treaties negotiated during this era, though those following the Indian Removal Act's ratification typically included specific stipulations requiring Native American tribes to relocate.
The 1833 Treaty of Chicago held significant historical importance as a key removal treaty implemented in the aftermath of the Indian Removal Act. It was formally identified as the second treaty to bear the name "Treaty of Chicago," following the earlier 1821 Treaty of Chicago. The agreement exemplified the federal government's systematic approach to displacing eastern tribes and opening their lands for American settlement and expansion westward.
The Indian Wars encompass more than three centuries of armed conflict between the United States government, American settlers, and Indigenous nations — from the Powhatan Wars of the 1620s through the final Plains campaigns of the late 19th century. The eastern conflicts — King Philip's War (1675–1676), the Tuscarora War (1711–1715), and the Creek and Seminole Wars — largely ended organized Indigenous resistance east of the Mississippi by the 1840s. On the Great Plains, the Sioux Wars (1854–1890), Red River War (1874–1875), and Nez Perce War (1877) followed the displacement wrought by the transcontinental railroad and the near-extinction of the American bison — an estimated 30 to 60 million animals reduced to fewer than 1,000 by 1890. The Ghost Dance religious movement and the massacre at Wounded Knee (December 29, 1890), in which US cavalry killed approximately 250 Lakota men, women, and children, marked the effective end of armed resistance. The Dawes Act (1887) allotted reservation land to individual families, opening millions of acres to white settlement and reducing Indigenous landholdings by about two-thirds over the following decades.
