"Anyone interested in the Gullah must ask how they have managed to keep their special identity and so much more of their African cultural heritage than any other group of Black Americans. The answer is to be found in the warm, semitropical climate of coastal South Carolina and Georgia; in the system of rice agriculture adopted there in the 1700s; and in a disease environment imported unintentionally from Africa. These factors combined almost three hundred years ago to produce an atmosphere of geographical and social isolation among the Gullah which has lasted, to some extent, up until the present day."
