During the American Revolution, many Natives fought with the British. At the Treaty of Paris (1783), Britain gave most Native lands to America. George Washington and Americans wanted to civilize and educate Natives. The Civilization Fund Act of 1819 supported this process. Americans thought that some Natives were civilized. These were the Five Civilized Tribes. They included the Cherokee, Chickasaw, Choctaw, Creek and Seminole tribes.
