The history of sexual slavery in the United States is the history of slavery for the purpose of sexual exploitation as it existed in the United States.

Early Americas

It is contended by some that as early as the 1490s Christopher Columbus had established trade in sex slaves on Hispaniola, which included sex slaves as young as 9. Within 25 years of being colonized, the Native population of Hispaniola drastically declined, due to the effects of enslavement, massacre, and infectious disease.

However, others consider this contention to have arisen from a misreading of primary documents. Columbus does mention the selling of slaves, but as atrocities of a rebelling faction. He continues with this comment, "I declare solemnly that a great number of men have been to the Indies, who did not deserve baptism in the eyes of God or men, and who are now returning thither.” Christopher Columbus, “Letter of the Admiral to the (quondam) nurse of the Prince John, written near the end of the year 1500,” Select Letters of Christopher Columbus (London: Hakluyt Society, 1870), p.165.

Under chattel slavery

Because of the power relationships at work, slave women in the United States were at high risk for rape and sexual abuse.Moon, p. 234. Their children were repeatedly taken away from them and sold as farm animals; usually they never saw each other again. Many slaves fought back against sexual attacks, and some died resisting. Others carried psychological and physical scars from the attacks.Marable, p. 74. Sexual abuse of slaves was partially rooted in a patriarchal Southern culture that treated black women as property or chattel. Southern culture strongly policed against sexual relations between white women and black men on the purported grounds of racial purity but, by the late 18th century, the many mixed-race slaves and slave children showed that white men had often taken advantage of slave women.

Wealthy planter widowers, notably such as John Wayles and his son-in-law Thomas Jefferson, took slave women as concubines; each had six children with his partner: Elizabeth Hemings and her daughter Sally Hemings (the half-sister of Jefferson's late wife), respectively. Both Mary Chesnut and Fanny Kemble, wives of planters, wrote about this issue in the antebellum South in the decades before the Civil War. Sometimes planters used mixed-race slaves as house servants or favored artisans because they were their children or other relatives. As a result of centuries of slavery and such relationships, DNA studies have shown that the vast majority of African Americans also have historic European ancestry, generally through paternal lines. Concubine slaves were the only female slaves who commanded a higher price than skilled male slaves.

The breeding of enslaved people was the attempt by a slave-owner to increase the reproduction of his victims for profit.Marable, Manning, How capitalism underdeveloped Black America: problems in race, political economy, and society South End Press, 2000, p 72 It included forced sexual relations between male and female enslaved people, encouraging slave pregnancies, sexual relations between master and slave to produce enslaved children, and favoring enslaved females who had many children.Marable, ibid, p 72 The prohibition on the importation of slaves into the United States after 1808 limited the supply of enslaved people in the United States. This came at a time when the invention of the cotton gin enabled the expansion of cultivation in the uplands of short-staple cotton, leading to clearing lands cultivating cotton through large areas of the Deep South, especially the Black Belt. The demand for labor in the area increased sharply and led to an expansion of the internal slave market. At the same time, the Upper South had an excess number of slaves because of a shift to mixed-crops agriculture, which was less labor-intensive than tobacco. To add to the supply of enslaved people, slaveholders looked at the fertility of slave women as part of their productivity, and intermittently forced the women to have large numbers of children.

During this time period, the terms "breeders", "breeding slaves", "child bearing women", "breeding period", and "too old to breed" became familiar.Smith, Julia Floyd (1991) Slavery and Rice Culture in Low Country Georgia, 1750-1860 University of Tennessee Press, 104. The historian E. Franklin Frazier, in his book The Negro Family, stated that "there were masters who, without any regard for the preferences of their slaves, mated their human chattel as they did their stock." Ex-slave Maggie Stenhouse remarked, "Durin' slavery there were stockmen. They was weighed and tested. A man would rent the stockman and put him in a room with some young women he wanted to raise children from."Work Projects Administration, Slave Narratives: A Folk History of Slavery in the United States from Interviews with Former Slaves, Arkansas Narratives, Part 6, Kessinger Publishing, 2004, p. 154. As it became popular on many plantations to breed slaves for strength, fertility, or extra labor, there grew many documented instances of "breeding farms" in the United States. Slaves were forced to conceive and birth as many new slaves as possible. The largest farms were located in Virginia and Maryland. Because the industry of slave breeding came from a desire for larger than natural population growth of slaves, slaveowners often turned towards systematic practices for creating more slaves. Female slaves "were subjected to repeated rape or forced sex and became pregnant again and again", even by incest. In horrific accounts of former slaves, some stated that hoods or bags were placed over their heads to prevent them from knowing who they were forced to have sex with. Journalist William Spivey wrote, "It could be someone they know, perhaps a niece, aunt, sister, or their own mother. The breeders only wanted a child that could be sold."

In Louisiana

From the beginning of African slavery in the North American colonies, slaves were often viewed as property, rather than people. Plaçage, a formalized system of concubinage among slave women or free people of color, developed in Louisiana and particularly New Orleans by the 18th century. The plaçage system developed from the predominance of white men among early colonial populations, who took women as consorts from Native Americans and enslaved Africans. In this period there was a shortage of European women, as the colonies were dominated in the early day by male explorers and colonists. Given the harsh conditions in Louisiana, persuading women to follow the men was not easy. France sent females convicted along with their debtor husbands, and in 1719, deported 209 women felons "who were of a character to be sent to the French settlement in Louisiana."Katy F. Morlas, "La Madame et la Mademoiselle," graduate thesis in history, Louisiana State University and Agricultural and Mechanical College, 2003 France also relocated young women and girls known as King's Daughters () to the colonies of Canada and Louisiana for marriage.

Through warfare and raids, Native American women were often captured to be traded, sold, or taken as wives. At first, the colony generally imported male Africans to use as slave labor because of the heavy work of clearing to develop plantations. Over time, it also imported African female slaves. Marriage between the races was forbidden according to the Code Noir of the eighteenth century, but interracial sex continued. The upper class European men during this period often did not marry until their late twenties or early thirties. Premarital sex with an intended white bride, especially if she was of high rank, was not permitted socially.

White male colonists, often the younger sons of noblemen, military men, and planters, who needed to accumulate some wealth before they could marry, took women of color as consorts before marriage. Merchants and administrators also followed this practice if they were wealthy enough.

Post-emancipation After the enslaved people were emancipated, many states passed anti-miscegenation laws, which prohibited interracial marriage between whites and non-whites. But this did not stop some white men from taking sexual advantage of black women by using their social positions under the Jim Crow system and white supremacy, or in other parts of the country by ordinary power and wealth dynamics.

The Chinese Tanka females were sold from Guangzhou to work as prostitutes for the overseas Chinese male community in the United States. During the California Gold Rush in the late 1840s, Chinese merchants transported thousands of young Chinese girls, including babies, from China to the United States and sold them into sexual slavery within the red light district of San Francisco. Girls could be bought for as cheap as $40 (about $1104 in 2013 dollars) in Guangzhou, and sold for $400 (about $11,040 in 2013 dollars) in the United States. Many of these girls were forced into opium addiction and lived their entire lives as prostitutes. Anglo-American doctors claimed that opium smoking led to increased involvement in prostitution by young white women and to genetic contamination via miscegenation by Chinese men.Ahmad, p. 47–48. Anti-Chinese advocates believed America faced a dual dilemma: opium smoking was ruining moral standards and Chinese labor was lowering wages and taking jobs away from European-Americans.Ahmad, p.51. Slum residents often frequented the brothels and opium dens of Chinatown in the late 1880s and early 1890s.Heap, p.34. However, by the mid-1890s, slum inhabitants rarely participated in Chinese brothels or opium smoking, but instead were shown fake opium joints where Chinese actors and their white wives staged illicit scenes for the benefit of their audiences.

The Page Act of 1875 restricted the immigration of Chinese women in reaction to racially charged fears about prostitution, sexually transmitted diseases, and American cultural morality. The Donaldina Cameron House was founded by San Francisco women in 1876 to help Chinese women forced into sexual slavery. Anti-slavery laws were often poorly enforced against local organized gangs. Notable exceptions became known as the "Broken Blossom trials" in the 1930s, facilitated by the escape of Jeung Gwai Ying and the testimony of Wong So. (PDF version)

A few captives from Native American tribes who were used as slaves were not freed, when African-American slaves were emancipated. "Ute Woman", a Ute captured by the Arapaho and later sold to a Cheyenne, was one example. Used as a prostitute for sale to American soldiers at Cantonment in the Indian Territory, she lived in slavery until about 1880 when she died of a hemorrhage resulting from "excessive sexual intercourse".

White slavery panic

By the 19th century, most of America's cities had a designated, legally protected area of prostitution. Increased urbanization and young women entering the workforce led to greater flexibility in courtship without supervision. It is in this changing social sphere that a panic over "white slavery" began. This term referred to women being coerced, lured, or kidnapped for the purposes of prostitution. Many journalists and activists in the late nineteenth and early twentieth centuries imagined that coerced sex workers were mostly white women and that most traffickers were male immigrants and men of color; in reality, the identities of sex workers and sex traffickers were not as racially predetermined or gender-specific as made out to be. Historians debate the extent to which "white slavery" was a real phenomenon of widespread coerced sexual labor or a moral panic circulated by journalists and activists but generally agree that there was at least some exaggeration.
