It was against this backdrop that the three races met and mingled along the western shore of Narragansett Bay. Long before the end of the eighteenth century, miscegenation had become a problem for New England settlers, who, if they had no clear idea of the nature of Africans, had even less understanding of the nature of the growing number of mulattos. Unlike blacks, who might be of African, Caribbean, or American birth, mulattos were usually born in the New World and were, therefore, not only racially distinct from Africans and Europeans but culturally distinct as well. The New England colonies recognized them as a separate group. Massachusetts made the first distinction between blacks and mulattos in 1693, Connecticut did so in 1704, and Rhode Island and New Hampshire followed in 1714. In addition to sexual relations between blacks and whites, Native Americans and blacks also came together and produced children. Greene believes the lowly status assigned both groups in white dominated New England served to erase any distinction between them, and, as they were common victims of oppression, they naturally drew together. In any event, along the eastern seaboard there was a mixing of Native Americans, whites, and blacks during the colonial era.
