The subculture of American Negroes is perhaps the most deeply rooted of all American subcultures, since most black Americans are descended from ancestors who were on the North American continent long before those of the great majority of white Americans. And the blood of many of them is, in truth, mingled with that of the great white families of the colonial and Revolutionary periods. The achievements of this subculture, both in slavery and in freedom, are among the most exalted in human record. It is doubted whether any expression of the human spirit transcends the Negro spiritual.
