Northern Profits from Slavery

The effects of the New England slave trade were momentous. It was one of the foundations of New England's economic structure; it created a wealthy class of slave-trading merchants, while the profits derived from this commerce stimulated cultural development and philanthropy.

Whether it was officially encouraged, as in New York and New Jersey, or not, as in Pennsylvania, the slave trade flourished in colonial Northern ports. But New England was by far the leading slave merchant of the American colonies.

The first systematic venture from New England to Africa was undertaken in 1644 by an association of Boston traders, who sent three ships in quest of gold dust and black slaves. One vessel returned the following year with a cargo of wine, salt, sugar, and tobacco, which it had picked up in Barbados in exchange for slaves. But the other two ran into European warships off the African coast and barely escaped in one piece. Their fate was a good example of why Americans stayed out of the slave trade in the 17th century. Slave voyages were profitable, but Puritan merchants lacked the resources, financial and physical, to compete with the vast, armed, quasi-independent European chartered corporations that were battling to monopolize the trade in black slaves on the west coast of Africa. The superpowers in this struggle were the Dutch West India Company and the English Royal African Company. The Boston slavers avoided this by making the longer trip to the east coast of Africa, and by 1676 the Massachusetts ships were going to Madagascar for slaves. Boston merchants were selling these slaves in Virginia by 1678. But on the whole, in the 17th century New Englanders merely dabbled in the slave trade.

Then, around 1700, the picture changed. First the British got the upper hand on the Dutch and drove them from many of their New World colonies, weakening their demand for slaves and their power to control the trade in Africa. Then the Royal African Company's monopoly on African coastal slave trade was revoked by Parliament in 1696. Finally, the Assiento and the Treaty of Utrecht (1713) gave the British a contract to supply Spanish America with 4,800 slaves a year. This combination of events dangled slave gold in front of the New England slave traders, and they pounced. Within a few years, the famous "Triangle Trade" and its notorious "Middle Passage" were in place.

Rhode Islanders had begun including slaves among their cargo in a small way as far back as 1709. But the trade began in earnest there in the 1730s. Despite a late start, Rhode Island soon surpassed Massachusetts as the chief colonial carrier. After the Revolution, Rhode Island merchants had no serious American competitors. They controlled between 60 and 90 percent of the U.S. trade in African slaves. Rhode Island had excellent harbors, poor soil, and it lacked easy access to the Newfoundland fisheries. In slave trading, it found its natural calling. William Ellery, prominent Newport merchant, wrote in 1791, "An Ethiopian could as soon change his skin as a Newport merchant could be induced to change so lucrative a trade as that in slaves for the slow profits of any manufactory."[1]

Boston and Newport were the chief slave ports, but nearly all the New England towns -- Salem, Providence, Middletown, New London – had a hand in it. In 1740, slaving interests in Newport owned or managed 150 vessels engaged in all manner of trading. In Rhode Island colony, as much as two-thirds of the merchant fleet and a similar fraction of sailors were engaged in slave traffic. The colonial governments of Massachusetts, Rhode Island, New York, New Jersey, and Pennsylvania all, at various times, derived money from the slave trade by levying duties on black imports. Tariffs on slave import in Rhode Island in 1717 and 1729 were used to repair roads and bridges.

The 1750 revocation of the Assiento dramatically changed the slave trade yet again. The system that had been set up to stock Spanish America with thousands of Africans now needed another market. Slave ships began to steer northward. From 1750 to 1770, African slaves flooded the Northern docks. Merchants from Philadelphia, New York, and Perth Amboy began to ship large lots (100 or more) in a single trip. As a result, wholesale prices of slaves in New York fell 50% in six years.

On the eve of the Revolution, the slave trade "formed the very basis of the economic life of New England."[2] It wove itself into the entire regional economy of New England. The Massachusetts slave trade gave work to coopers, tanners, sailmakers, and ropemakers. Countless agents, insurers, lawyers, clerks, and scriveners handled the paperwork for slave merchants. Upper New England loggers, Grand Banks fishermen, and livestock farmers provided the raw materials shipped to the West Indies on that leg of the slave trade. Colonial newspapers drew much of their income from advertisements of slaves for sale or hire. New England-made rum, trinkets, and bar iron were exchanged for slaves. When the British in 1763 proposed a tax on sugar and molasses, Massachusetts merchants pointed out that these were staples of the slave trade, and the loss of that would throw 5,000 seamen out of work in the colony and idle almost 700 ships. The connection between molasses and the slave trade was rum. Millions of gallons of cheap rum, manufactured in New England, went to Africa and bought black people. Tiny Rhode Island had more than 30 distilleries, 22 of them in Newport. In Massachusetts, 63 distilleries produced 2.7 million gallons of rum in 1774. Some was for local use: rum was ubiquitous in lumber camps and on fishing ships. "But primarily rum was linked with the Negro trade, and immense quantities of the raw liquor were sent to Africa and exchanged for slaves. So important was rum on the Guinea Coast that by 1723 it had surpassed French and Holland brandy, English gin, trinkets and dry goods as a medium of barter."[3] Slaves costing the equivalent of £4 or £5 in rum or bar iron in West Africa were sold in the West Indies in 1746 for £30 to £80. New England thrift made the rum cheaply -- production cost was as low as 5½ pence a gallon -- and the same spirit of Yankee thrift discovered that the slave ships were most economical with only 3 feet 3 inches of vertical space to a deck and 13 inches of surface area per slave, the human cargo laid in carefully like spoons in a silverware case.

A list of the leading slave merchants is almost identical with a list of the region's prominent families: the Fanueils, Royalls, and Cabots of Massachusetts; the Wantons, Browns, and Champlins of Rhode Island; the Whipples of New Hampshire; the Eastons of Connecticut; Willing & Morris of Philadelphia. To this day, it's difficult to find an old North institution of any antiquity that isn't tainted by slavery. Ezra Stiles imported slaves while president of Yale. Six slave merchants served as mayor of Philadelphia. Even a liberal bastion like Brown University has the shameful blot on its escutcheon. It is named for the Brown brothers, Nicholas, John, Joseph, and Moses, manufacturers and traders who shipped salt, lumber, meat -- and slaves. And like many business families of the time, the Browns had indirect connections to slavery via rum distilling. John Brown, who paid half the cost of the college's first library, became the first Rhode Islander prosecuted under the federal Slave Trade Act of 1794 and had to forfeit his slave ship. Historical evidence also indicates that slaves were used at the family's candle factory in Providence, its ironworks in Scituate, and to build Brown's University Hall.[4]

Even after slavery was outlawed in the North, ships out of New England continued to carry thousands of Africans to the American South. Some 156,000 slaves were brought to the United States in the period 1801-08, almost all of them on ships that sailed from New England ports that had recently outlawed slavery. Rhode Island slavers alone imported an average of 6,400 Africans annually into the U.S. in the years 1805 and 1806. The financial base of New England's antebellum manufacturing boom was money it had made in shipping. And that shipping money was largely acquired directly or indirectly from slavery, whether by importing Africans to the Americas, transporting slave-grown cotton to England, or hauling Pennsylvania wheat and Rhode Island rum to the slave-labor colonies of the Caribbean.

Northerners profited from slavery in many ways, right up to the eve of the Civil War. The decline of slavery in the upper South is well documented, as is the sale of slaves from Virginia and Maryland to the cotton plantations of the Deep South. But someone had to get them there, and the U.S. coastal trade was firmly in Northern hands. William Lloyd Garrison made his first mark as an anti-slavery man by printing attacks on New England merchants who shipped slaves from Baltimore to New Orleans.

Long after the U.S. slave trade officially ended, the more extensive movement of Africans to Brazil and Cuba continued. The U.S. Navy never was assiduous in hunting down slave traders. The much larger British Navy was more aggressive, and it attempted a blockade of the slave coast of Africa, but the U.S. was one of the few nations that did not permit British patrols to search its vessels, so slave traders continuing to bring human cargo to Brazil and Cuba generally did so under the U.S. flag. They also did so in ships built for the purpose by Northern shipyards, in ventures financed by Northern manufacturers.

In a notorious case, the famous schooner-yacht Wanderer, pride of the New York Yacht Club, put in to Port Jefferson Harbor in April 1858 to be fitted out for the slave trade. Everyone looked the other way -- which suggests this kind of thing was not unusual -- except the surveyor of the port, who reported his suspicions to the federal officials. The ship was seized and towed to New York, but her captain talked (and possibly bought) his way out and was allowed to sail for Charleston, S.C.

Fitting out was completed there, the Wanderer was cleared by Customs, and she sailed to Africa where she took aboard some 600 blacks. On Nov. 28, 1858, she reached Jekyll Island, Georgia, where she illegally unloaded the 465 survivors of what is generally called the last shipment of slaves to arrive in the United States.
