Slavery was prominent presumably elsewhere in Africa long before the beginnings of the transatlantic slave trade. The maritime town of Lagos , Portugal , was the first slave market created in Portugal for the sale of imported African slaves – the Mercado de Escravos, opened in 1444. In 1441, the first slaves were brought to Portugal from northern Mauritania .] By 1552 black African slaves made up 10 percent of the population of Lisbon . In the second half of the 16th century, the Crown gave up the monopoly on slave trade and the focus of European trade in African slaves shifted from import to Europe to slave transports directly to tropical colonies in the Americas – in the case of Portugal , especially Brazil . In the 15th century one third of the slaves were resold to the African market in exchange of gold.
The Transatlantic slave trade peaked in the late 18th century, when the largest number of slaves were captured on raiding expeditions into the interior of West Africa . These expeditions were typically carried out by African kingdoms, such as the Oyo empire, the Ashanti Empire, the kingdom of Dahomey , and the Aro Confederacy. Europeans rarely entered the interior of Africa , due to fierce African resistance. The slaves were brought to coastal outposts where they were traded for goods.
An estimated 12 million Africans arrived in the Americas from the 16th to the 19th centuries. Of these, an estimated 645,000 were brought to what is now the United States . The usual estimate is that about 15 per cent of slaves died during the voyage. The white citizens of Virginia decided to treat the first Africans in Virginia as indentured servants. Over half of all European immigrants to Colonial America during the 17th and 18th centuries arrived as indentured servants. In 1655, John Casor, a black man, became the first legally recognized slave in the present United States . According to the 1860 U.S. census, 393,975 individuals, representing 8% of all US families, owned 3,950,528 slaves. One-third of Southern families owned slaves.
The largest number of slaves were shipped to Brazil . In the Spanish viceroyalty of New Granada, corresponding mainly to modern Panama , Colombia , and Venezuela , the free black population in 1789 was 420,000, whereas African slaves numbered only 20,000. Free blacks also outnumbered slaves in Brazil . In Cuba , by contrast, free blacks made up only 15% in 1827; and in Saint-Domingue (present-day Haiti ) it was a mere 5% in 1789. Some half-million slaves, most of them born in Africa , worked the booming plantations of Saint-Domingue.
Although the trans-Atlantic slave trade ended shortly after the American Revolution, slavery remained a central economic institution in the Southern states. All the Northern states passed emancipation acts between 1780 and 1804; most of these arranged for gradual emancipation. In the South, however, slavery expanded with the westward movement of population. Historian Peter Kolchin wrote, "By breaking up existing families and forcing slaves to relocate far from everyone and everything they knew" this migration "replicated (if on a reduced level) many of [the] horrors" of the Atlantic slave trade. Historian Ira Berlin called this forced migration the Second Middle Passage. Characterizing it as the "central event" in the life of a slave between the American Revolution and the Civil War, Berlin wrote that whether they were uprooted themselves or simply lived in fear that they or their families would be involuntarily moved, "the massive deportation traumatized black people, both slave and free." By 1860, 500,000 slaves had grown to 4 million. As long as slavery expanded, it remained profitable and powerful and was unlikely to disappear. Antislavery forces, however, proposed to put it on the path to extinction by stopping further expansion. If it became unprofitable, few people would spend the large sums of cash needed to buy and keep slaves, and the system would fade away quietly as it had in most countries in world history.
The plantation system, based on tobacco growing in Virginia, North Carolina, and Kentucky, and rice in South Carolina, expanded into lush new cotton lands in Georgia, Alabama, Mississippi—and needed more slaves. But slave importation became illegal in 1808. Although complete statistics are lacking, it is estimated that 1,000,000 slaves moved west from the Old South between 1790 and 1860. Most of the slaves were moved from Maryland , Virginia , and the Carolinas . Michael Tadman, in a 1989 book Speculators and Slaves: Masters, Traders, and Slaves in the Old South, indicates that 60–70% of interregional migrations were the result of the sale of slaves. In 1820 a child in the Upper South had a 30% chance to be sold south by 1860.
Political division over slavery was temporarily resolved by the Compromise of 1850 which sought to divide new territories between slave and free states. However, the status of Kansas was left unresolved, producing bloody clashes between pro-slavery and anti-slavery settlers. In 1860, the election of Abraham Lincoln as President on a program of limiting slavery led to the secession of Southern States and the outbreak of the US Civil War. Although Lincoln initially disclaimed any intention to interfere with slavery, the progress of the war produced the Emancipation Proclamation freeing slaves in Southern states still in revolt, and ultimately the Thirteenth Amendment to the United States Constitution in December 1865, which ended legalized slavery in the United States.
