Negro superseded colored as the most polite word for African Americans at a time when black was considered more offensive.[7][better source needed][failed verification] In 17th-century colonial America, the term Negro had been also, according to one historian, used to describe Native Americans.[8] John Belton O'Neall's The Negro Law of South Carolina (1848) stipulated that "the term negro is confined to slave Africans, (the ancient Berbers) and their descendants. It does not embrace the free inhabitants of Africa, such as the Egyptians, Moors, or the negro Asiatics, such as the Lascars."[9] The American Negro Academy was founded in 1897, to support liberal arts education. Marcus Garvey used the word in the names of black nationalist and pan-Africanist organizations such as the Universal Negro Improvement Association (founded 1914), the Negro World (1918), the Negro Factories Corporation (1919), and the Declaration of the Rights of the Negro Peoples of the World (1920).
