Slave trade in the United States
The internal slave trade in the United States, also known as the domestic slave trade, the Second Middle Passage
Economists say that transactions in the inter-regional slave market were driven primarily by differences in the
The disparity in productivity created arbitrage opportunities for traders to exploit, and it facilitated regional specialization in labor production. Due to a lack of data, particularly with regard to slave prices, land values, and export totals for slaves, the true effects of the domestic slave trade, on both the economy of the Old South and general migration patterns of slaves into southwest territories, remain uncertain. These have served as points of contention among economic historians. The physical effect of forced labor (on remote plantation camps plagued with yellow fever, cholera, and malaria), and social-emotional effect of family separation in American slavery, was nothing short of catastrophic.
History
The history of the domestic slave trade can very clumsily be divided into three major periods:
- 1776 to 1808: This period began with the Declaration of Independence and ended when the importation of slaves from Africa and the Caribbean was prohibited under federal law in 1808; the importation of slaves was prohibited by the Continental Congress during the American Revolutionary War but resumed locally afterwards, primarily through the ports of Wilmington, North Carolina (until 1785),[3] Savannah, Georgia (until 1798),[4] and Charleston, South Carolina (reopened the transatlantic slave trade in December 1803 and imported 39,075 enslaved people of African descent between 1804 and 1808).[5]
- 1808 to Indian removal and invention of long-staple cotton gin (1830s): This period of national expansion can arguably be backdated to the Louisiana Purchase of 1803.[5] One New Orleans historian found evidence of that the "queen of the trade" was open for business in first years the 19th century, but "it was not till the 1820s had well set in that the number of American slave merchants grew to impressive proportions" and by 1827 "New Orleans had become the chief center of the slave trade in the lower South"[6]: 151
- 1830s to American Civil War: This period began when the combination of new lands open for settlement and higher profits for cotton growers led to a massive population transfer of enslaved people from the Chesapeake region to the Mississippi River basin.[7]
End of the slave trade
The domestic slave trade wilted during American Civil War—there was a measurable price drop between 1860 and 1862, due to "market uncertainty" discouraging speculators.[8] In May 1861, a "Southern Mississippian" who seemed to oppose secession even though "no man in Mississippi has a larger proportion of his property in negroes" wrote the Louisville Courier that "The secessionists are carrying out the principles and wishes of the abolitionists. Likely negroes could not be sold here at $500 in good money. Negro traders are as scarce here as in Boston."[9] Still, the business remained brisk and prices rose in the protected interior of the CSA, and according to historian Robert Colby, "Confederates nevertheless interpreted the health of the slave trade as embodying that of their nation."[10]
Times got still harder for traders when the Union blockade prevented the trafficking of people from, say, rural Missouri to New Orleans.[11] But the slave trade, as an integral part of slavery, persisted throughout Confederate-controlled territory until very nearly the end of the war. Ziba B. Oakes was still listing slaves in Charleston, South Carolina newspaper ads on November 1864.[12] A handful of American-flagged ships were still moving enslaved people from Africa to Cuba and Brazil until 1867, when American participation in the slave trade ended once and for all.[4]
Economics
Slavery was a massive element of the U.S. national economy and even more so the economy of the South: "In 1860, enslaved people were worth more than $3 billion (~$83 billion in 2023) to their owners. In today's economy, that would be equivalent to $12.1 trillion or 67 percent of the 2015 U.S. gross domestic product...The unpaid fruits of their labors created an interest so strong that between 1861 and 1865, Confederate leaders staked hundreds of thousands of lives and the future of their civilization on it."[13] As told by historian Frederic Bancroft, "Slave trading was considered a sign of enterprise and prosperity."[14]
The internal slave trade among colonies emerged in 1760 as a source of labor in early America.[15] It is estimated that between 1790 and 1860 approximately 835,000 slaves were relocated to the American South.[16]
The biggest sources for the domestic slave trade were "exporting" states in the Upper South, especially Virginia and Maryland, and as well as Kentucky, North Carolina, Tennessee, and Missouri.[17] From these states most slaves were imported into the Deep South, to the "slave-consuming states," especially Georgia, Alabama, Mississippi, and Louisiana.[18] Robert Fogel and Stanley Engerman attribute the larger proportion of the slave migration due to planters who relocated their entire slave populations to the Deep South to develop new plantations or take over existing ones.[19] Walter Johnson disagrees, finding that only one-third of the population movement south was due to wholesale relocation of slave owner and chattel, while the other two-thirds of the shift was due to the commerce in slaves.[20]
Contributing factors
Soil exhaustion and crop changes
Historians who argue in favor of
Land availability from Indian removal
With the forced Indian removal by the US making new lands available in the Deep South, there was much higher demand there for workers to cultivate the labor-intensive sugar cane and cotton crops. The extensive development of cotton plantations created the highest demand for labor in the Deep South.[21][22]
Cotton gin
At the same time, the invention of the cotton gin in the late 18th century transformed short-staple cotton into a profitable crop that could be grown inland in the Deep South. Settlers pushed into the South, expelling the Five Civilized Tribes and other Native American groups. The cotton market had previously been dominated by the long-staple cotton cultivated primarily on the Sea Islands and in the coastal South Carolina Lowcountry. The consequent boom in the cotton industry, coupled with the labor-intensive nature of the crop, created a need for slave labor in the Deep South that could be satisfied by excess supply further north.[19]
The increased demand for labor in the Deep South pushed up the price of slaves in markets such as New Orleans, which became the fourth-largest city in the country based in part on profits from the slave trade and related businesses. The price differences between the Upper and Deep South created demand. Slave traders took advantage of this arbitrage opportunity by buying at lower prices in the Upper South and then selling slaves at a profit after taking or transporting them further south.[19] Some scholars believe there was an increasing prevalence in the Upper South of "breeding" slaves for export. The proven reproductive capacity of enslaved women was advertised as selling point and a feature that increased value.[19]
Resolve financial deficits
Although not as significant as the exportation of slaves to Deep South, farmers and land owners who needed to pay off loans increasingly used slaves as a cash substitute. This had also contributed to the growth of the internal slave trade.[19]
Statistics
Economic historians have offered estimates for the annual revenue generated by the inter-regional slave trade for exporters that range from $3.75[23] to $6.7 million.[19]
The demand for prime-aged slaves, from the ages of 15 to 30, accounted for 70 percent of the slave population relocated to the Deep South.[19] Since the ages of slaves were often unknown by the traders themselves, physical attributes such as height often dictated demand in order to minimize asymmetric information.[19]
Without the inter-regional slave trade, it is possible that forced migration of slaves would have occurred naturally due to natural population pressures and the subsequent increase in land prices.[23] In 1965, William L. Miller contended that, "it is even doubtful whether the interstate slave traffic made a net contribution to the westward flow of the population."[23]
Importation, piracy, and interstate kidnapping
The transatlantic slave trade not prohibited under federal law until 1808. Imports from Africa to Southern states were ongoing from 1776 until that time, most often through the ports of Charleston and Savannah. Post-1808 importation of slaves to the United States from the Caribbean, South America, and Africa was illegal but piracy continued until the opening of the American Civil War.
Kidnapping into slavery in the United States was a going concern for the duration. Unaccompanied children and people of color traveling to port cities and border states were particularly vulnerable. There are more than a few accounts of armed gangs breaking into the homes of free people in the dead of night and carrying away whole families. The lucky ones were sometimes redeemed from the local slave jail by friends or lawyers before they were shipped south.
Breeding of slave children for sale
Gentlemen in Virginia and Maryland were quick to realize the value of young slaves, and to organize breeding of them. This was not treated as any more shameful than the breeding of calves:
It is utterly impossible that anything should exist more horrible than the American slave breeding. The history of it is this:—The Americans abolished the foreign slave-trade earlier than England, but with this consolation – no small comfort to so money-loving a race as the slave holders – that by such abolition they enhanced the price of the slaves then in America, by stopping the competition in the home market of the supply of newly imported slaves. Why, otherwise, was not the home trade stopped as well as the foreign? The reply is obvious.
To supply the home slave trade, an abominable, a most hideous, most criminal, and most revolting practice of breeding negroes exclusively for sale has sprung up, and especially, we are told, in Virginia. There are breeding plantations for producing negroes, as there are with us breeding farms for producing calves and lambs. And as our calf and lamb breeders calculate the number of males to the flock of females, similar calculations are made by the traffickers in human flesh. One instance was mentioned to me of a human breeding farm in America, which was supplied with two men and twelve women. Why should I pollute my page with a description of all that is immoral and infamous in such practices? —But only think of the wretched mothers whom nature compels to love their children—children torn from them for ever, just at the period that they could requite their mother's love! The wretched, wretched mother? Who I can depict the mother's distraction, her madness? 'But their maternal feelings are,' says a modern writer, 'treated with as much contemptuous indifference as those of the cows and ewes whose calves and lambs are sent to the English market.'—Richmond Enquirer, 16 October 1838[25]
According to Frederic Bancroft in Slave-Trading in the Old South (1931) young female slaves were also considered an excellent financial investment: "Not only real estate, but also stocks, bonds and all other personal property were little prized in comparison with slaves...Absurd as it now seems, slaves, especially girls and young women, because of prospective increase, were considered the best investment for persons of small means."[14]
Profits
Irish economic theorist
The returns gained by traders from the sale price of slaves were offset by both the fall in the value of land, that resulted from the subsequent decrease in the marginal productivity of land, and the fall in the price of output, which occurred due to the increase in market size as given by westward expansion.[26] Kotlikoff suggested that the net effect of the inter-regional slave trade on the economy of the Old South was negligible, if not negative.[26]
The profits realized through the sale and shipment of enslaved people were in turn reinvested in banking, railroads, and even colleges. A striking example of the connection between the domestic slave trade and higher education can be found in the
In the words of one scholar, slaveholders were, fundamentally, "speculator[s]" who hoped "to endow [their] progeny for generations to come" through the "capital accumulation" represented in the growing numbers of people they enslaved. The returns from slave ownership, therefore, were long-term and intergenerational.
— Robert Crosby, An Unholy Traffic, 2024[29]
Markets and traders
In their day, slave traders were called everything from broker, the entirely generic term preferred in Charleston,[14] to nigger-trader, a term that appears in both slave traders' own descriptions of themselves in oral interviews and in records of African-American folk music of the era. Negro trader and slave dealer were common occupational titles that appeared in census records and city directories.[14] In the earliest years of the market, "dozens of independent speculators...bought lots of ten or so slaves, generally on credit, in Upper-South states like Virginia and Maryland."[7] In 1836 a Philadelphia paper characterized the work of negro brokers: "They conceive the business of pawn brokers and merchandize brokers. They lend money on the security of slaves, taking the latter as a pledge, to be sold if the pledge be not redeemed. They advance cash on slaves to be sold at auction or private sale, deducting from the proceeds of sale their commission and expenses. They buy and sell slaves upon commission, to suit their customers, and sometimes doubtless, buy and sell free people of color on pretence of their being slaves."[30]
The argument has been made that the domestic slave trade was one that resulted in "superprofits" for traders. But Jonathan Pritchett points to evidence that there were a significant number of firms engaged in the market, a relatively dense concentration of these firms, and low barriers to entry. He says that traders who were exporting slaves from the Upper South were price-taking, profit-maximizers acting in a market that achieved a long-run competitive equilibrium.[19]
Using an admittedly limited set of data from
Evans suggests that interstate slave traders earned a wage greater than that of an alternative profession in skilled mechanical trades.
Chesapeake cities like Baltimore, Alexandria, Washington, D.C., and Richmond were "slave collecting and resale centers."[35] Major slave-buying markets were located Charleston, Savannah, Memphis, and above all, New Orleans.[14] Economists estimate that more than 135,000 enslaved people were sold in New Orleans between 1804 and 1862.[8] Some traders only bought and sold locally; smaller interstate trading companies would typically have both upper south and lower south locations, for buying and selling, respectively.[20] Larger interstate firms, like Franklin & Armfield, and Bolton, Dickens & Co., might have locations or traders under contract in a dozen cities.[14] Dealers in the upper south worked to collect what they called "shipping lots"—enough people to be worth spending time and money arranging for their transport south.[36] There was a trading season, namely winter and spring, because summer and autumn were planting and harvesting time; farmers and plantation owners generally would not buy or sell until that year's crop was in.[20]
The notion that slave traders were social outcasts of low reputation, even in the South, was initially promulgated by defensive southerners and later by figures like historian
The writer has drawn in this work only one class of the negro-traders. There are all varieties of them, up to the great wholesale purchasers, who keep their large trading-houses; who are gentlemanly in manners and courteous in address; who, in many respects, often perform actions of real generosity; who consider slavery a very great evil, and hope the country will at some time be delivered from it, but who think that so long as clergyman and layman, saint and sinner, are all agreed in the propriety and necessity of slave holding, it is better that the necessary trade in the article be conducted by men of humanity and decency, than by swearing, brutal men, of the
Tom Loker school. These men are exceedingly sensitive with regard to what they consider the injustice of the world, in excluding them from good society, simply because they undertake to supply a demand in the community, which the bar, the press, and the pulpit, all pronounce to be a proper one. In this respect, society certainly imitates the unreasonableness of the ancient Egyptians, who employed a certain class of men to prepare dead bodies for embalming, but flew at them with sticks and stones the moment the operation was over, on account of the sacrilegious liberty which they had taken. If there is an ill-used class of men in the world, it is certainly the slave-traders; for, if there is no harm in the institution of slavery, if it is a divinely-appointed and honourable one, like civil government and the family state, and like other species of property relation, then there is no earthly reason why a man may not as innocently be a slave-trader as any other kind of trader.
Product and price
Male slaves were worth more than female slaves; one study found that on average males sold for nine percent more than females.[8] But female slaves came with "increase"—children born enslaved to an enslaved woman were saleable, thus providing excellent return on investment.[43] Prime age slaves were those ages 10 to 35, or more broadly enslaved children older than eight and enslaved adults younger than 40, because people of those ages were presumed to be able work and/or reproduce for an extended period of time.[44] As a rule, there was an inverse correlation between age and price for enslaved people over 40. For example, in 1835 South Carolina, when Ann Ball spent almost US$80,000 (equivalent to $2,362,839 in 2023) to buy 215 enslaved people from the estates of her deceased relatives, she made a point to buy several apparently elderly slaves (Old Rachel, Old Lucy, Old Charles) and the lowest-priced single person was Old Peg, purchased for US$20 (equivalent to $590.71 in 2023), compared to an average price of $371 per.[45][46] Another illustration of comparative slave prices is from the District of Columbia Compensated Emancipation program: "The highest priced slave was a blacksmith worth $1800, and the lowest [priced was] a two-months-old mulatto baby, worth $25."[47]
There were several broad categories of work for which enslaved people were purchased: agriculture, domestic service, mechanical, and commercial-industrial. Agricultural workers grew and processed cash crops like cotton and sugar, or managed herds of cattle in Texas, etc. Domestics worked in the household or in hotels and taverns, cooking, cleaning, laundering clothes, producing household goods, and providing childcare, including supplying the free white babies they cared for with their own human milk. Mechanics were expensive and prized: these were the smiths, builders, craftsmen, etc. Finally, commercial-industrial slaves were put to work all over the south in ironworks, steamboat boiler rooms, on railroads, at gin-houses, bagasse-burners, lumber mills, turpentine stills, and so forth. The owner of a slave might or might not be a slave's employer: owners often rented, leased, or "hired out" their slaves.
According to historian Bancroft, in the great slave market that was New Orleans, enslaved people imported from Virginia, and to a lesser extent Maryland and South Carolina, were advertised as an especially desirable product, whereas "the many slaves brought from Missouri and Kentucky" were rarely advertised by their place of origin.[14] "Acclimated" slaves known to be immune to yellow fever and other communicable diseases also commanded a premium.[48]
According to economist
Routes
There were four main methods of forced transportation of the enslaved. Initially, transport was either on foot or by sailing ship, but following the popularization of the railroad and the steamboat in the 1840s, both were commonly used.
- Overland transport: In many cases slaves were relocated simply by walking them in chains, double-file, in groups of 50 to 200, between counties or states. Chained columns of slaves could be expected to travel about 20 mi (32 km) a day.[20]
- Ocean-going ship: The coastwise slave trade, in which enslaved people were transported on commercial sailing ships and steamships between the East Coast and the Gulf Coast via the Atlantic Ocean and the Gulf of Mexico, was busiest between the Chesapeake Bay region and the cities of the Mississippi Delta, but virtually any ship that departed south of the Mason-Dixon Line to points further south would have likely carried slaves for sale. A typical trip from the port at Norfolk to New Orleans might be a three-week journey.[20] A statistical analysis of all known records of Baltimore–New Orleans slave shipments from 1820 to 1860 found that brigs were the type of ship used in about half of all shipments, and voyages commonly lasted between 21 and 35 days.[50]
- Transportation via navigable inland rivers: Wheeling, Virginia, and Louisville, Kentucky, down the Cumberland River from Nashville, and up the Red River of the South through Louisiana and Arkansas. Any navigable inland waterway or ship that was used to transport goods that were produced with slave labor was also used to transport slaves to buyers: the Delaware River was used to take slaves to market in colonial Pennsylvania; the Savannah River connected planters to the cotton market at Augusta, Georgia and, on the opposite bank, the slave market at Hamburg, South Carolina; the Chattahoochee River was access to the slave markets at Columbus, Georgia, etc.
- Rail transport: As early as 1841, Southern railroad companies bought male slaves to build railroads, with at least 85 of 113 railroads in the former Confederacy having used enslaved labor for construction within and between states.[51]
Specific overland routes
- Montgomery became the leading slave market in Alabama because of its accessibility by both water and land, due to its connection to both the Federal Road and the Alabama River, the latter of which saw steamboats shipping slaves up the river from Mobile.
- The Natchez Trace was used to bring slaves from middle Tennessee and to the Forks of the Road and Vicksburg slave markets in Mississippi.
- Kentucky slave traders supplied the Mississippi River valley via the Mobile and Ohio Railroad, the Louisville and Nashville Railroad, and the southern reaches of the Illinois Central Railroad.[52]
Law
In the early 19th century several slave states had unenforced statutes prohibiting the interstate slave trade. These laws were undermined in many ways; for example, "
State | Notes |
---|---|
Alabama | Limitations on interstate slave trading passed 1832[55] |
Delaware | Banned imports and exports of slaves at statehood (1787)[56] |
Kentucky | Non-Importation Act passed 1833,[57] repealed 1849 |
Louisiana | Imports banned 1826–1828;[58] "...slavers circumvented rules like Louisiana's strict requirement that captives entering the state bear certificates of good character by manufacturing fake certificates."[13] |
Georgia | Imports banned 1788, repealed in 1856[59] |
Mississippi | Banned in 1832 constitution, never enforced[13] |
Tennessee | Banned 1827–1855; unenforced[13] |
