In 1662, the colony of Virginia passed a law that changed the future of slavery in North America. It declared that the status of a child would be determined by the condition of the mother. If an enslaved African woman gave birth to a child, that child would be enslaved too, regardless of whether the father was free, white or even the woman’s enslaver.
The principle became known as partus sequitur ventrem, Latin for “the offspring follows the womb.” The law itself was a Virginia law, not a law that suddenly applied throughout America. However, the principle became enormously influential, and similar rules were adopted in other slaveholding colonies and states. Together, these laws helped establish hereditary slavery, in which children could be born into bondage simply because their mothers were enslaved.
The significance was enormous. Slavery no longer had to be imposed on each generation through capture or purchase. An enslaved woman could give birth to children who were legally enslaved from the moment they entered the world, and those children could later have children who inherited the same condition.
The Story of Elizabeth Key
One important story connected to the development of the law was that of Elizabeth Key, the daughter of an Englishman, Thomas Key, and an enslaved African woman. Elizabeth argued that she should be free because her father was a free Englishman. She eventually won her freedom in court in the 1650s.
Key’s case exposed a problem for Virginia’s emerging slave system. If a child’s status could follow a free father, then children born to enslaved women and free Englishmen could potentially be free. That created uncertainty for slaveholders who wanted slavery to become permanent and hereditary.
In 1662, Virginia lawmakers resolved that uncertainty. They declared that children would be considered “bond or free” according to the condition of their mothers. The father’s status no longer determined the child’s condition.
This was a crucial change because it made the children of enslaved women economically valuable to their enslavers. A child born to an enslaved woman was not simply another member of her family. Under the law, the child was born enslaved and became the property of the enslaver.
Similar rules concerning the inheritance of enslaved status later developed in other English colonies and American slave states.
The principle became particularly important because it tied slavery to the maternal line. A white man could father a child with an enslaved woman, but his freedom did not make the child free. The child’s legal condition followed the mother.
Over time, this helped create a racialized system in which slavery could reproduce itself from generation to generation.
The Connection to Slave Breeding
This is where the history of slave breeding becomes important.
Slave breeding refers to the deliberate interference by enslavers in the reproduction of slaves to increase the number of people they owned. Practices varied, and historians do not describe American slavery as one centrally organized nationwide breeding program. Instead, forced reproduction occurred through different practices on different plantations and in different regions.
Enslavers could pressure or force enslaved African men and women into sexual relationships, interfere with marriages, separate couples, encourage pregnancies and value enslaved people according to their perceived ability to produce children. Because children born to enslaved women inherited their mothers’ enslaved status, reproduction could directly increase an enslaver’s property.
An enslaved woman could therefore be exploited in two connected ways: as a laborer and as someone whose children would become enslaved.
This did not mean enslaved women willingly participated in the system. They resisted it in many ways, including attempting to protect their children, resisting sexual coercion and, in some documented cases, attempting to prevent or terminate pregnancies.
Frederick Douglass and Caroline
One of the clearest accounts of slave breeding comes from Frederick Douglass, who escaped slavery and became one of America’s most important abolitionists.
In his autobiography, Douglass described a 20 year old enslaved woman named Caroline, whom his enslaver, Edward Covey, acquired specifically because he considered her useful for reproduction. Douglass wrote that Covey forced Caroline into a sexual arrangement with an enslaved man named Bill Smith and kept them together at night in the expectation that they would produce children.
When Caroline eventually gave birth to twins, Douglass described Covey’s reaction as one of satisfaction because the children represented an increase in his enslaved “stock.”
This account is particularly important because it shows the economic logic of forced reproduction from the perspective of someone who witnessed slavery firsthand. The children were not regarded simply as new members of a family. To the enslaver, they represented additional human property.
The 1808 Turning Point
The economic importance of reproduction became even greater after the United States prohibited the international importation of enslaved Africans in 1808. The ban did not end slavery or the buying and selling of enslaved people. Instead, as cotton plantations expanded and demand for labor increased, slaveholders became more dependent on the domestic slave trade and the reproduction of the enslaved population.
This created an even greater financial incentive for slave breeding and forced reproduction. Because partus sequitur ventrem made the children of enslaved women enslaved from birth, an enslaved woman could give birth to a child who became her master’s property and could later be forced to work or sold for profit. Some enslavers forced enslaved men and women into sexual relationships, while others sexually assaulted and raped enslaved women themselves, knowing that any children born from those pregnancies would also be enslaved.
The domestic slave trade also grew rapidly, transporting enslaved Africans from states such as Virginia and Maryland to plantations farther south and west. Children born into slavery could be sold alongside adults, meaning mothers could lose their children through the same market that profited from their reproduction.
After 1808, the slave system increasingly relied on birth, breeding and domestic sales to replenish its enslaved population. The womb of an enslaved African woman had become economically valuable to a system that treated her children as property.
This was the brutal legacy of partus sequitur ventrem. By tying a child’s legal status to the condition of the mother, the law allowed slavery to pass from mother to child and from one generation to the next. It made slavery hereditary before a child had even taken its first breath, turning birth itself into one of the mechanisms through which the institution of slavery survived and expanded.
