Choctaw are the largest tribe belonging to the branch of the Muskogean family that includes the Chickasaw, Creek (Muscogee), and Seminole. According to oral history, the tribe originated from Nanih Waya, a sacred hill near present-day Noxapater, Mississippi. Nanih Waya means "productive or fruitful hill, or mountain." During one of their migrations, they carried a tree that would lean, and every day the people would travel in the direction the tree was leaning. They traveled east and south for sometime until the tree quit leaning, and the people stopped to make their home at this location, in present-day Mississippi. The people have made difficult transitions throughout their history. In 1830, the Choctaw who were removed by the United States from their southeastern U.S. homeland to Indian Territory became known as the Choctaw Nation of Oklahoma.
