Interracial relationships, common-law marriages, and marriages occurred since the earliest colonial years, especially before slavery hardened as a racial caste associated with people of African descent in the British colonies. Virginia and other English colonies passed laws in the 17th century that gave children the social status of their mother, according to the principle of partus sequitur ventrem, regardless of the father's race or citizenship. This overturned the principle in English common law by which a man gave his status to his children – this had enabled communities to demand that fathers support their children, whether legitimate or not. The change increased white men's ability to use slave women sexually, as they had no responsibility for the children. As master as well as father of mixed-race children born into slavery, the men could use these people as servants or laborers or sell them as slaves. In some cases, white fathers provided for their multiracial children, paying or arranging for education or apprenticeships and freeing them, particularly during the two decades following the American Revolution. (The practice of providing for the children was more common in French and Spanish colonies, where a class of free people of color developed who became educated and property owners.) Many other white fathers abandoned the mixed-race children and their mothers to slavery.
