Enslavement

"Europeans' enslavement of Native Americans has a long history. Ponce de Leon went to Florida not really to seek the mythical fountain of youth; his main business was to seek gold and capture slaves for Hispaniola. In New England, Indian slavery led directly to African slavery: the first blacks imported there, in 1638, were brought from the West Indies in exchange for Native Americans from Connecticut. On the eve of the New York City slave rebellion of 1712, in which Native and African slaves united, about one resident in four was enslaved and one slave in four was American Indian. A 1730 census of South Kingston, Rhode Island, showed 935 whites, 333 African slaves and 223 Native American slaves."
