This project investigates people of mixed African, European, and sometimes Native American ancestry, commonly referred to as "mulattoes," in English colonial North America and the early United States republic. This research deconstructs nascent African American stratification by examining various types of privilege that allowed people of mixed heritage to experience upward social mobility, with a special focus on access to freedom from slavery and servitude in the colonies and states of the southeast Atlantic Coast. Additionally, this work provides a framework for understanding U.S. mixed-race ideologies by following the trajectory of how people of mixed descent and their families viewed themselves and how they were perceived by the broader societies in which they lived. This study contributes to historiographical and contemporary discussions associated with mixed-heritage peoples, ideas of racial mixture, "whiteness," and African American identity.
