Curtis Act of 1898
The Curtis Act of 1898 was an amendment to the United States Dawes Act; it resulted in the break-up of tribal governments and communal lands in Indian Territory (now Oklahoma) of the Five Civilized Tribes of Indian Territory: the Choctaw, Chickasaw, Muscogee (Creek), Cherokee, and Seminole. These tribes had been previously exempt from the 1887 General Allotment Act (Dawes Act) because of the terms of their treaties.
