During the eighteenth and nineteenth centuries, the Mattaponi Indians incorporated native traditions with English habits, largely converting to Christianity. In the early twentieth century, many Virginia Tribes struggled to preserve their identity and culture due to the Racial Integrity Act of 1924. The Racial Integrity Act of 1924 and subsequent legislation banned interracial marriage in Virginia and asked for voluntary racial identifications on birth and marriage certificates. “White” was defined as having no trace of African ancestry, while all other people, including Indians, were defined as “colored.” To accommodate elite Virginians who claimed Pocahontas and John Rolfe as ancestors, the law allowed for those who had “one-sixteenth or less of the blood of the American Indian and have no other non-Caucasic blood [to] be deemed to be white persons.” The laws essentially erased Virginia Indians as a category of people.
