The institution of slavery in North America existed from the earliest years of the colonial period until 1865 when the Thirteenth Amendment permanently abolished slavery throughout the entire United States. It was also abolished among the sovereign Indian tribes in Indian Territory by new peace treaties which the US required after the war.
For most of the seventeenth and part of the eighteenth centuries, male slaves outnumbered female slaves, making the two groups' experiences in the colonies distinct. Living and working in a wide range of circumstances and regions, African-American women and men encountered diverse experiences of enslavement. With increasing numbers of imported African women, as well as those born into slavery in the colonies, slave sex ratios leveled out between 1730 and 1750. "The uniqueness of the African-American female's situation is that she stands at the crossroads of two of the most well-developed ideologies in America, that regarding women and that regarding the Negro." Living both female and black identities, enslaved African women faced both racism and sexism.
From 1700 to 1740 an estimated number of 43,000 slaves were imported into Virginia, and almost all but 4,000 were imported directly from Africa. Recent scholarship suggests that the number of women and men imported in this period was more or less equal and included a high number of children. As most were from West Africa, its cultures were central in mid- to late- eighteenth-century slave life in Virginia. African values were prevalent and West African women's cultures had strong representations. Some prevalent cultural representations were the deep and powerful bonds between mother and child, and among women within the larger female community. Among the Igbo ethnic group in particular (from present-day Nigeria), which comprised between one-third and one-half of incoming slaves in the early eighteenth century, female authority (the omu) "ruled on a wide variety of issues of important to women in particular and the community as a whole." The Igbo represented one group of people brought to the Chesapeake, but in general, Africans came from an extremely diverse range of cultural backgrounds. All came from worlds where women's communities were strong, and were introduced into a patriarchal and violently racist and exploitative society; white men typically characterized all black women as passionately sexual, to justify their sexual abuse and miscegenation.
