Throughout the 17th and 18th centuries people were kidnapped from the continent of Africa, forced into slavery in the American colonies and exploited to work as indentured servants and labor in the production of crops such as tobacco and cotton. By the mid-19th century, America’s westward expansion and the abolition movement provoked a great debate over slavery that would tear the nation apart in the bloody Civil War. Though the Union victory freed the nation’s four million enslaved people, the legacy of slavery continued to influence American history, from the Reconstruction, to the civil rights movement that emerged a century after emancipation and beyond.
When Did Slavery Start?
Hundreds of thousands of Africans, both free and enslaved, aided the establishment and survival of colonies in the Americas and the New World. However, many consider a significant starting point to slavery in America to be 1619, when the privateer The White Lion brought 20 African slaves ashore in the British colony of Jamestown, Virginia. The crew had seized the Africans from the Portugese slave ship Sao Jao Bautista.
Throughout the 17th century, European settlers in North America turned to enslaved Africans as a cheaper, more plentiful labor source than indentured servants, who were mostly poor Europeans.
Though it is impossible to give accurate figures, some historians have estimated that 6 to 7 million enslaved people were imported to the New World during the 18th century alone, depriving the African continent of some of its healthiest and ablest men and women.
In the 17th and 18th centuries, enslaved Africans worked mainly on the tobacco, rice and indigo plantations of the southern coast, from the Chesapeake Bay colonies of Maryland and Virginia south to Georgia.
After the American Revolution, many colonists—particularly in the North, where slavery was relatively unimportant to the agricultural economy—began to link the oppression of enslaved Africans to their own oppression by the British, and to call for slavery’s abolition.
Did you know? One of the first martyrs to the cause of American patriotism was Crispus Attucks, a former enslaved man who was killed by British soldiers during the Boston Massacre of 1770. Some 5,000 Black soldiers and sailors fought on the American side during the Revolutionary War.
But after the Revolutionary War, the new U.S. Constitution tacitly acknowledged the institution of slavery, counting each enslaved individual as three-fifths of a person for the purposes of taxation and representation in Congress and guaranteeing the right to repossess any “person held to service or labor” (an obvious euphemism for slavery).
Cotton Gin
In the late 18th century, with the land used to grow tobacco nearly exhausted, the South faced an economic crisis, and the continued growth of slavery in America seemed in doubt.
Around the same time, the mechanization of the textile industry in England led to a huge demand for American cotton, a southern crop whose production was limited by the difficulty of removing the seeds from raw cotton fibers by hand.
But in 1793, a young Yankee schoolteacher named Eli Whitney invented the cotton gin, a simple mechanized device that efficiently removed the seeds. His device was widely copied, and within a few years the South would transition from the large-scale production of tobacco to that of cotton, a switch that reinforced the region’s dependence on enslaved labor.
Slavery itself was never widespread in the North, though many of the region’s businessmen grew rich on the slave trade and investments in southern plantations. Between 1774 and 1804, all of the northern states abolished slavery, but the institution of slavery remained absolutely vital to the South.
Though the U.S. Congress outlawed the African slave trade in 1808, the domestic trade flourished, and the enslaved population in the United States nearly tripled over the next 50 years. By 1860 it had reached nearly 4 million, with more than half living in the cotton-producing states of the South.

History of Slavery
Enslaved people in the antebellum South constituted about one-third of the southern population. Most lived on large plantations or small farms; many masters owned fewer than 50 enslaved people.
Land owners sought to make their enslaved completely dependent on them through a system of restrictive codes. They were usually prohibited from learning to read and write, and their behavior and movement was restricted.
Many masters raped enslaved women, and rewarded obedient behavior with favors, while rebellious enslaved people were brutally punished. A strict hierarchy among the enslaved (from privileged house workers and skilled artisans down to lowly field hands) helped keep them divided and less likely to organize against their masters.
Marriages between enslaved men and women had no legal basis, but many did marry and raise large families; most slave owners encouraged this practice, but nonetheless did not usually hesitate to divide families by sale or removal.
Slave Rebellions
Rebellions among enslaved people did occur—notably ones led by Gabriel Prosser in Richmond in 1800 and by Denmark Vesey in Charleston in 1822—but few were successful.
The revolt that most terrified enslavers was that led by Nat Turner in Southampton County, Virginia, in August 1831. Turner’s group, which eventually numbered around 75 Black men, murdered some 55 white people in two days before armed resistance from local white people and the arrival of state militia forces overwhelmed them.
Supporters of slavery pointed to Turner’s rebellion as evidence that Black people were inherently inferior barbarians requiring an institution such as slavery to discipline them, and fears of similar insurrections led many southern states to further strengthen their slave codes in order to limit the education, movement and assembly of enslaved people.
Abolitionist Movement
In the North, the increased repression of southern Black people only fanned the flames of the growing abolitionist movement.
From the 1830s to the 1860s, the movement to abolish slavery in America gained strength, led by free Black people such as Frederick Douglass and white supporters such as William Lloyd Garrison, founder of the radical newspaper The Liberator, and Harriet Beecher Stowe, who published the bestselling antislavery novel Uncle Tom’s Cabin.
While many abolitionists based their activism on the belief that slaveholding was a sin, others were more inclined to the non-religious “free-labor” argument, which held that slaveholding was regressive, inefficient and made little economic sense.
Free Black people and other antislavery northerners had begun helping enslaved people escape from southern plantations to the North via a loose network of safe houses as early as the 1780s. This practice, known as the Underground Railroad, gained real momentum in the 1830s. Conductors like Harriet Tubman guided escapees on their journey North, and “stationmasters” included such prominent figures as Frederick Douglass, Secretary of State William H. Seward and Pennsylvania congressman Thaddeus Stevens. Although estimates vary widely, it may have helped anywhere from 40,000 to 100,000 enslaved people reach freedom.
The success of the Underground Railroad helped spread abolitionist feelings in the North; it also undoubtedly increased sectional tensions, convincing pro-slavery southerners of their northern countrymen’s determination to defeat the institution that sustained them.
