What is "cusabo"

The Cusabo (also Corsaboy) were a group of historic Native American tribes who lived along the coast of the Atlantic Ocean in what is now South Carolina, approximately between present-day Charleston and south to the Savannah River, at the time of European encounter. English colonists often referred to them as one of the Settlement Indians of South Carolina, tribes who settled among the colonists.

Five of the groups were recorded by the settlers as having spoken a common language, although one distinctly different from the major language families known nearby, such as Algonquian, Iroquoian, Muskogean and Siouan. With the English settling on their land at Charleston beginning in the 17th century, the Cusabo developed a relationship of accommodation with the colony that persisted through the early 18th century. After the Yamasee War of 1712, surviving tribal members migrated to join the Creek or Catawba.
