 The Cherokee language is part of the Iroquoian language group.In the 19th century, James Mooney, an American ethnographer, recorded one oral tradition that told of the tribe having migrated south in ancient times from the Great Lakes region, where other Iroquoian-speaking peoples lived; however, anthropologist Thomas R. Whyte writes that the origin of the proto-Iroquoian language was likely the Appalachian region and the split between Northern and Southern Iroquoian languages began 4,000 years ago.By the 19th century, European settlers in the United States classified the Cherokee of the Southeast as one of the "Five Civilized Tribes", because they were agrarian and lived in permanent villages and began to adopt some cultural and technological practices of the European American settlers.
