The Atlantic Slave Trade and the Growth of Slavery

The number of southerners of African ancestry (nearly all of them slaves) rocketed from just over 20,000 in 1700 to well over 400,000 in 1770. The black population increased nearly three times faster than the South’s briskly growing white population. Consequently, the proportion of southerners of African ancestry grew from 20 percent in 1700 to 40 percent in 1770.

Southern colonists clustered into two distinct geographic and agricultural zones. The colonies in the upper South, surrounding Chesapeake Bay, specialized in growing tobacco, as they had since the early seventeenth century. Throughout the eighteenth century, nine out of ten southern whites and eight out of ten southern blacks lived in the Chesapeake region. The upper South retained a white majority during the eighteenth century. [[LP Photo: P05.04 Bethlehem, Pennsylvania /ROA_704115_05_P04.JPEG]]

Bethlehem, Pennsylvania This view of Bethlehem, Pennsylvania, in 1757 dramatizes the profound transformation of the natural landscape humans wrought in the eighteenth century. In less than twenty years, precisely laid-out orchards and fields replaced forests and glades. By carefully penning their livestock (lower center right) and fencing their fields (lower left), farmers safeguarded their livelihoods from the risks and disorders of untamed nature. Individual farmsteads (lower center) and brick town buildings (upper center) integrated the bounty of the land with community life. Few eighteenth-century communities were as orderly as Bethlehem, but many effected a comparable transformation of the environment.

In the lower South, a much smaller cluster of colonists inhabited the coastal region and specialized in the production of rice and indigo (a plant used to make blue dye). Lower South colonists made up only 5 percent of the total population of the southern colonies in 1700 but inched upward to 15 percent by 1770. South Carolina was the sole British colony along the southern Atlantic coast until 1732. (North Carolina, founded in 1711, was largely an extension of the Chesapeake region.) Georgia was founded in 1732 as a refuge for poor people from England. Georgia’s leaders banned slaves from 1735 to 1750, but few settlers arrived until after 1750, when the prohibition on slavery was lifted and slaves flooded in. In South Carolina, in contrast to Georgia and every other British mainland colony, slaves outnumbered whites almost two to one; in some low-country districts, the ratio of blacks to whites exceeded ten to one.

The enormous growth in the South’s slave population occurred through natural increase and the flourishing Atlantic slave trade (Table 5.1 and Map 5.3). Slave ships brought almost 300,000 Africans to British North America between 1619 and 1780. Of these Africans, 95 percent arrived in the South and 96 percent arrived during the eighteenth century. Unlike indentured servants and redemptioners, these Africans did not choose to come to the colonies. Most of them had been born into free families in villages located within a few hundred miles of the West African coast. Although they shared African origins, they came from many different African cultures, such as Akan, Angolan, Asante, Bambara, Gambian, Igbo, and Mandinga, among others. They spoke different languages, worshipped different deities, observed different rules of kinship, grew different crops, and recognized different rulers. The most important experience they had in common was enslavement. [[LP Map: M05.03 The Atlantic Slave Trade– MAP ACTIVITY /ROA_704115_05_M03.JPEG]]

Figure 5.3: MAP 5.3 The Atlantic Slave Trade Although the Atlantic slave trade lasted from about 1450 to 1870, it peaked during the eighteenth century, when more than six million African slaves were imported to the New World. Only a small fraction of these slaves were taken to British North America. Most went to sugar plantations in Brazil and the Caribbean.

Captured in war, kidnapped, or sold into slavery by other Africans, they were brought to the coast, sold to African traders who assembled slaves for resale, and sold again to European or colonial slave traders or ship captains, who packed two hundred to three hundred or more aboard ships that carried them on the Middle Passage across the Atlantic and then sold them yet again to colonial slave merchants or southern planters.

Olaudah Equiano Painted after he had bought his freedom, this portrait evokes Equiano’s successful acculturation to eighteenth-century English customs. In his Interesting Narrative, Equiano wrote that he “looked upon [the English] . . . as men superior to us [Africans], and therefore I had the stronger desire to resemble them, to imbibe their spirit and imitate their manners.”
Library of Congress, 3b01988.

Olaudah Equiano published an account of his enslavement that hints at the common experiences of millions of other Africans swept up in the slave trade. In 1756 when he was eleven years old, Equiano was kidnapped by Africans in what is now Nigeria, who sold him to other Africans, who in turn eventually sold him to a slave ship on the coast. Equiano wrote that he “had never heard of white men or Europeans, nor of the sea,” and he feared that he was “going to be killed” and “eaten by those white men with horrible looks, red faces, and loose hair.” Once the ship set sail, many of the slaves, crowded together in suffocating heat fouled by filth of all descriptions, died from sickness. “The shrieks of the women and the groans of the dying rendered the whole a scene of horror almost inconceivable,” Equiano recalled. Most of the slaves on the ship were sold in Barbados, but Equiano and other leftovers were shipped off to Virginia, where he “saw few or none of our native Africans and not one soul who could talk to me.” Equiano felt isolated and “exceedingly miserable” because he “had no person to speak to that I could understand.” Finally, the captain of a tobacco ship bound for England purchased Equiano, and he traveled as an enslaved sailor between North America, England, and the West Indies for ten years until he succeeded in buying his freedom in 1766.

Only about 15 percent of the slaves brought into the southern colonies came aboard ships from the West Indies, as Equiano did. All the other slaves brought into the southern colonies came directly from Africa, and almost all the ships that brought them (roughly 90 percent) belonged to British merchants. Most of the slaves on board were young adults, with men usually outnumbering women two to one. Children under the age of fourteen, like Equiano, typically accounted for no more than 10 to 15 percent of a cargo.

Mortality during the Middle Passage varied considerably from ship to ship. On average, about 15 percent of the slaves died, but sometimes half or more perished. The average mortality among the white crew of slave ships was often nearly as bad. In general, the longer the voyage lasted, the more people died. Slaves and crew succumbed not only to epidemic diseases such as smallpox and dysentery but also to acute dehydration caused by fluid loss from perspiration, vomiting, and diarrhea combined with a severe shortage of drinking water.

Normally, an individual planter purchased at any one time a relatively small number of newly arrived Africans, or new Negroes, as they were called. New Negroes were often profoundly depressed, demoralized, and disoriented. Planters expected their other slaves—either those born into slavery in the colonies (often called country-born or creole slaves) or Africans who had arrived earlier—to help new Negroes become accustomed to their strange new surroundings. Planters’ preferences for slaves from specific regions of Africa aided slaves’ acculturation (or seasoning, as it was called) to the routine of bondage in the southern colonies. Chesapeake planters preferred slaves from Senegambia, the Gold Coast, or—like Equiano—the Bight of Biafra, which combined accounted for about 40 percent of Africans imported to the Chesapeake. South Carolina planters favored slaves from the central African Congo and Angola regions, the origin of about 40 percent of the slaves they imported. Although slaves spoke many different languages, enough linguistic and cultural similarities existed that they could usually communicate with other Africans from the same region.

New Africans had to adjust to the physical as well as the cultural environment of the southern colonies. Slaves who had just endured the Middle Passage were poorly nourished, weak, and sick. In this vulnerable state, they encountered the alien diseases of North America without having developed a biological arsenal of acquired immunities. As many as 10 to 15 percent of newly arrived Africans died during their first year in the southern colonies. Nonetheless, the large number of newly enslaved Africans made the influence of African culture in the South stronger in the eighteenth century than ever before—or since.

> CONSIDER CAUSE AND EFFECT

Why did the population of the southern colonies increase so much more than that of the northern colonies?

While newly enslaved Africans poured into the southern colonies, slave mothers bore children, which caused the slave population in the South to grow rapidly. Slave owners encouraged these births. Thomas Jefferson explained, “I consider the labor of a breeding [slave] woman as no object, that a [slave] child raised every 2 years is of more profit than the crop of the best laboring [slave] man.” Although slave mothers loved and nurtured their children, the mortality rate among slave children was high, and the ever-present risk of being separated by sale brought grief to many slave families. Nonetheless, the growing number of slave babies set the southern colonies apart from other New World slave societies, where mortality rates were so high that deaths exceeded births. The high rate of natural increase in the southern colonies meant that by the 1740s the majority of southern slaves were country-born.
