Circa1865

Southern colonists were greatly alarmed at the great influx of African slaves being transported into their midst by British and New England ships by the mid-1700s. Both Virginia and North Carolina taxed the importation of slaves to discourage the practice, only to be overruled by the King who sought productive colonial plantations.

By 1750, Rhode Island was the center of the transatlantic slave trade, which continued to at least 1859. When discussing the antebellum period it is more accurate to speak of all the States as free, and the Northern States properly referred to as former slaveholding States, along with some being former slave trading States.

Southern Abolition Societies

“Slavery continued to be recognized within the South as a grave social problem. Perhaps Southerners were less concerned about it than they had been in the Revolutionary period, but during the course of the Missouri debate, responsible Southern spokesmen openly admitted that slavery was evil; and ten years later there occurred the greatest and most searching discussion of the nature and problem of slavery that was ever held in the South, the debate in the Virginia legislature in 1832.

Several antislavery journals appeared in the slave States: The Emancipator, founded in East Tennessee in 1820; The Genius of Universal Emancipation, which was moved to Tennessee from Ohio in 1821 and was later moved to Baltimore; and the Abolition Intelligencer, founded in Kentucky in 1822.

Benjamin Lundy, editor of the Genius of Universal Emancipation, estimated in 1827 that there were 106 antislavery societies with 5,150 members in the slave States whereas there were only 24 such societies with 1,475 members in the free States, not counting 10 or 12 in Illinois about which he could get no information.

But these facts by no means indicate that Southerners generally were conscience-stricken over slavery . . . [and] the hostility of some Southerners to slavery was founded on something very different from sympathy for the oppressed. When Governor David Holmes of Mississippi warned that “The evils arising from this odious practice [the slave trade] are constantly . . . increasing,” and there would be serious results “unless the traffic is wholly prohibited,” his concern was for the welfare of the Mississippi white man.

Governor [Thomas Mann] Randolph of Virginia put the matter very bluntly. He deplored the “error of our ancestors in copying a civil institution from savage Africa,” because as he reasoned, “The want of moral motives and a defect of intelligence, the too common absence of settled character, that marks the race [degraded] by slavery, if not by nature,” was injurious to the State of Virginia.

There was much support throughout the South in the 1820s for plans to deport Negroes . . . Haiti, Africa and unsettled parts of the western territories of the United States were suggested as possible places to which Negroes could be sent, but the only serious effort that came out of the discussion was the organization in Washington in 1817, of the American Colonization Society.”

Alexander H. Stephen’s criticism of President James Polk sending American troops to the Rio Grande in July 1845 and threatening Mexico, inspired his arraignment of Lincoln in 1861 for leading the country into an avoidable war.

In Lincoln’s case, his party’s governors provided the troops for his unconstitutional actions and invasion of Southern States, and subjugated a free people with an “oath of allegiance administered at the point of a bayonet.” Stephens foresaw the treatment the South would receive.

Only Congress May Draw the Sword

“From [his] first speech in Congress to his last before the war, his straight line of endeavor was to preserve the Union under the Constitution. His opposition to Texan annexation was not pleasing to the South . . . and the first to bring him into national prominence, contained the oft-quoted sentences which revived against him at the South the charges of abolitionism while at the North he was accused of laboring for slavery extension:

“My reason for wishing it [the slavery limit] settled in the beginning, I do not hesitate to make known. I fear the excitement growing out of the agitation hereafter may endanger the harmony and even existence of our present Union . . . I am no defender of slavery in the abstract. I would rejoice to see all the sons of Adam’s family in the enjoyment of those rights set forth in the Declaration of Independence as natural and inalienable . . .”

The right of the Union to “acquire territory” and the wisdom of doing so were questioned. He declared for expansion but against imperialism: “This [annexation] is an important step settling the principle of our future extension. We are reminded of the growth of the Roman Empire which fell of its own weight; and of England, who is hardly able to keep together her extensive parts. Rome extended her dominions by conquest, she compelled provinces to bear the yoke; England extends hers upon the principle of colonization; her distant dependencies are subject to her laws but are deprived of the rights of representation.

With us, a new system has commenced, characteristic of the age. It is a system of a Republic formed by the union of separate independent States, yielding so much of their sovereign powers as are necessary for national and foreign purposes, and retaining all others for local and domestic objects. Who shall undertake to say how far this system may not go?”

He said, speaking of Mexican territory:

“No principle is more dangerous than that of compelling other people to adopt our form of government. It is not only wrong in itself, but contrary to the whole spirit and genius of liberty we enjoy.”

Asking if the Mexican war was waged for conquest:

“If so, I protest . . . I am no enemy to the extension of our domain . . . but it is not to be accomplished by the sword. We can only properly enlarge by voluntary accessions.”

In his denunciation of [President James] Polk’s abuse of power . . . :

“Only Congress can constitutionally draw the sword. The President cannot. The war was brought upon us while Congress was in session and without our knowledge. The new and strange doctrine is put forth that Congress has nothing to do with the conduct of the war; that the President is entitled to uncontrolled management; that we can do nothing but vote men and money to whatever extent his folly and caprice may dictate.

Neighboring States may be subjugated, extensive territories annexed, provincial governments erected, the rights of conscience violated, and the oath of allegiance administered at the point of the bayonet . . .”

(Recollections of Alexander H. Stephens, Myrta L. Avary, editor, LSU Press, 1998, excerpts pp. 31-32)

The Founders were wary of a standing army and gave only to Congress the power to raise troops and declare war. Should a sitting president venture to call for troops at his whim, as did Lincoln, the republic of those Founders was at an end.

Lincoln and the governors of Pennsylvania, Massachusetts and New York who supplied him with troops for the purpose of waging war against other States and adhering to their enemies, were all were guilty of treason according to Article III, Section 3 of the United States Constitution.

There was a peaceful alternative which was not pursued by Lincoln and his party, and Southern Unionists pleas for peaceful diplomacy and compromise were ignored in favor of intentional duplicity at Charleston.

Exercising All the War Powers of Congress

“The day after Fort Sumter surrendered President Lincoln called on the several States for seventy-five thousand militia for ninety days service. The troops were to suppress “combinations too powerful to be suppressed by the ordinary course of judicial proceedings, or by the powers vested in the Marshals by law, a curiously legalistic phraseology probably adopted in an attempt to bring the proclamation under the Acts of 1795 and 1807 governing the calling out of the posse comitatus.

Amid immense enthusiasm, the established militia regiments in the eastern cities moved at once. Pennsylvania troops, a few companies, reached Washington the next day; Massachusetts troops came within four days, in spite of the violent resistance to the transfer of the regiment across Baltimore between the railroad stations; New York’s first regiment was but a day behind Massachusetts.

The Governors of Maryland, Virginia, North Carolina, Kentucky, Tennessee, Arkansas and Missouri sharply declined to honor the President’s requisition for troops to be used against the seven States of the Confederacy. The Governor of Delaware reported that he had no authority for raising troops.

Neither, for that matter, had President Lincoln, under strict construction of the laws. In his first proclamation he called Congress into special session, but not to meet until the Fourth of July, more than two and a half months later.

In the meanwhile, free from interference, he drove ahead to organize his war, making laws or breaking them as he had need to, creating armies, enlarging the Navy, declaring blockades, exercising all the war powers of Congress.

Before the guns spoke at Sumter and the President answered with his call for troops, there was everywhere, in the North, in the Border States unhappily torn between loyalties, and even in those States which had seceded, a strong party for peace. The fire of Sumter swept away all that in the North; the call of Lincoln for troops, in the South.

The New Orleans True Delta, which had opposed secession and sought peace, “spurned the compact with them who would enforce its free conditions with blood” — an attitude that was general among those who were not original secessionists.”

(The Story of the Confederacy, Robert Selph Henry, Bobbs-Merrill Company, 1931, excerpts pp. 34-35)

Alexander Hamilton was no friend of the Articles of Confederation and the decentralized republic it represented, but he did know the limits of newly-created federal power within the new constitution. His view was that States retained any authority not specifically delegated, and that State troops, as in 1861-1865, would constitutionally resist any invasion to preserve their independence and sovereignty.

James Madison wrote of this as well, stating that more than one State might band together, as in the later Confederate States of America, to resist any and all encroachments on State sovereignty by the federal agent created by the States.

Alexis de Toqueville, the French traveler in the America of 1831-32, saw firsthand the powers of “this strange new democratic monster” that would within thirty years gain control of the federal government and consolidate all, by force, into one common mass.

Saddled with Another Absolutist Regime

“In Toqueville’s opinion, the many levels of responsibility acted as buffers against the tyranny of the majority that ordinarily characterized democracy. Then United States possessed a centralized government but not a centralized administration.

To what extent American self-government was an outgrowth of the federal constitution, or merely a by-product of their habits and experiences, remains to be seen. This much, however, is clear: no subject so agitated the founding fathers as the possible loss of local responsibility under a federal government. The new constitution had to be designed in a way that maximized State autonomy.

As Hamilton put it in Federalist 62, “The equal vote allowed to each State [i.e. in the Senate] is at once a constitutional recognition of the portion of sovereignty remaining in the individual States, and an instrument for preserving that residual sovereignty.”

Although Hamilton favored a centralized economic authority, he argued that the federal government could not legitimately use the taxing power as an excuse to interfere in the internal government of the States. In Federalist 28, he argued that State militias would be called out to resist invasions of sovereignty.

[James] Madison concurred, and in Federalist 46 suggested that the States would band together to prevent such encroachments. Even the arch-federalist John Marshall declared (in McCulloch v. Maryland) that “no political dreamer was ever wild enough to think of breaking down the lines which separate the States, and of compounding the American people into one common mass.”

Interference in the life of local communities had been one of the complaints against the royal government. The anti-Federalists were afraid that, by adopting the Federal Constitution, they were saddling themselves with another absolutist regime. Mass democracy, as Toqueville realized, was dangerous.”

(The Politics of Human Nature, Thomas Fleming, Transaction Publishers, 1988, excerpts pg. 200)

In early March 1861, the new Confederate States government adopted a virtual free tariff, which quickly brought Northern merchants to their economic senses. Moses Kelly of the US Department of the Interior overheard many Southerners state that Southern ports planning direct trade with Europe “promised to deprive northern merchants of their position as middlemen and to eject northern manufacturers from the southern market in favor of European competitors.”

Further, the Philadelphia Press asked rhetorically: “If South Carolina is permitted to establish a free port with impunity, and to invite to her harbor all the ships of foreign nations, would not disaster in that event fall upon all our great northern interests?” It accurately predicted “an early reawakening of the Union sentiment in New York.” Thus true reason for total war against the South and destruction of her economic base was clearly revealed.

“Force of a Most Formidable Character”

“[By March 1861] it was evident that northern businessmen had carefully measured the consequences of disunion and the collapse of central authority and decided that they were intolerable. They had called for appeasement, but when that failed they were soon reconciled to the use of force.

Many of them concluded that property had received about as much damage from the crisis as it could, that “no new phase which the [secession] movement may take can have any further effect.”

Stocks had reached their lowest average quotations in December when the government seemed weakest, and even the approach of war failed to depress them that much again. As one commercial writer saw it, business was already suffering “all it could from a state of actual war.” And when war finally came the northern men of property united behind Lincoln to save the Union and restore the prestige of the national government.

When Yankee capitalists finally endorsed the use of military force against secessionists, they accepted the final remedy for a solemn threat to their property and future profits. Inevitably the holders of government securities looked upon disunion as a menace to their investments.

One conservative nervously declared: “So long as the right of secession is acknowledged, United States bonds must still be denounced as entirely unsafe property to hold . . .” To permit States to leave the Union at will, he warned, would mean that the “United States stocks are really worth no more than old Continental money.” With this in mind, when another government loan was offered in January, an observer shrewdly predicted: “Every dollar [New] York takes binds her capitalists to the Union, and the North.”

A basic tenet of the northern middle classes was that the value of property depended upon political stability. In effect, secessionists had made an indirect attack upon the possessions of every property holder. They had invited property-less Northerners, the revolutionary “sans culottes,” “the unwashed and unterrified,” to precipitate the country into “rough and tumble anarchy.” This “social and moral deterioration” might easily infect the lower classes with the radical idea “that a raid upon property can be justified by the plea of necessity.”

Conservatives looked apprehensively at the “immense foreign element” in northern cities and feared that revolution was “nearer our doors than we imagine.” From these recent immigrants could come the mobs to set aside all law and order and, with “revolver and stiletto,” sink the nation “into confusion and riotous chaos.” The only alternative, it was repeatedly argued, was to enforce respect for the Federal government everywhere.

[Northern] businessmen gradually became convinced that Southern independence would be almost fatal to northern commerce. American maritime power in the Caribbean and Gulf . . . would vanish . . . exclude the North from their trade . . . Even trade with the Pacific would be at the mercy of the South.

The northern monopoly in the coasting trade was a further casualty of the disunion movement. Vowing that he had “an interest and proprietorship in the Union of all these States,” [a] New Yorker concluded that secession would have to be checkmated by “force of a most formidable character.”

(And the War Came: The North and the Secession Crisis, 1860-1861 Kenneth M. Stampp, LSU Press, 1950, excerpts pp. 223-230)

The northeastern United States of the late 1820s were sufficiently prosperous to have a large group of “substantial citizens” . . . manufacturers and journalists interested in the cause of domestic industry, and their purpose was to influence the passage of a new tariff act.” For the most part these men were industrialists and focused on increased profits, not national stability.

The South was in economic distress at the time and the new, higher tariff “seemed to end once and for all any prospect of relief, and many [Southerners] were ready for outright rebellion, even as New England had been in 1814.”

For South Carolina to nullify a federal law it viewed as obnoxious and injurious to its citizens, was a full expression of the Tenth Amendment — inserted into the Constitution for an obvious purpose. The next logical step of an injured State would be peacefully withdrawing from a political union which no longer fulfilled the purposes for which it was formed. And if withdrawal was met with violence, revolution was next.

The American Right of Revolution

“Controversial as Nullification was in the absence of original records before 1828-1833, Americans still continued to believe in federalism and States’ rights. In the words of Alexander Johnston, “Almost every State in the Union in turn declared its own sovereignty and denounced as almost treasonable similar declarations by other States.”

Herman V. Ames in fact compiled a “collection of documents on the relation of the States to the Federal Government” in 1911. They were “selected especially,” he observed, “with a view to illustrate the development of the “compact theory” of the Constitution and the doctrine of “State Rights,’ State opposition to the Federal Judiciary, and the different phases of the slavery controversy, culminating in the secession movement.”

That we believe otherwise today, in Nullification’s unconstitutionality and [John C.] Calhoun’s and the South’s apostasy from the beliefs of the founders and framers, is explained by another and longer era of historical amnesia by which original intentions as described herein in length were not so much forgotten as between 1789 and 1819, but purposely misinterpreted both to nullify the Nullifiers of South Carolina and to establish a mythical history for a new nation in the making that was the central development of the years after the War of 1812 and until the Civil War.

While this more liberal-democratic-egalitarian-nationalist America was yet inchoate as the confused politics of the 1820s and 1830s inform us, it was there nonetheless in Jacksonian Democracy and nationalism and radical abolitionism which were, it is forgotten, minority movements. The union of the States persisted with the 18th century Whig-republican ideology still extant as the core set of beliefs within the misnamed Democratic party that was really republican with a small “r.”

The liberal-in-a-neo-Hamiltonian sense-Whigs of the 19th century co-existed long enough to make party politics interesting and popular and the preserve the old union of the States. If not republicans, most Americans before the Civil War remained at least federalists. Nullification may have come and gone, but the “right of revolution” continued to be accepted as an original intention and the ultimate means to preserve liberty.”

(Nullification, A Constitutional History, 1776-1833, Volume II: James Madison and the Constitutionality of Nullification, 1787-1828, W. Kirk Wood, University Press of America, 2009, excerpts pg. 105)

Though the war had a chilling effect upon Cincinnatians trading southward, by 1863 it was a boomtown supplying the Northern military and “filling large orders for iron and steel products, uniforms and wagons. In a few years, the profits amassed into great fortunes.”

Lincoln’s administration maintained the patriotism of the West with lucrative military supply contracts. Cincinnati’s political system became corrupt, and its leaders notorious for controlling elections and manipulating judges and juries.

The Courthouse Riot of 1884 occurred after German worker Wilhelm Berner and mulatto accomplice Joe Palmer murdered their employer, William Kirk. Though the judge, after the trial and confessions, sentenced both to 20 years in prison, the bribed jury returned a verdict of simple manslaughter.

The “Boss” Cox mentioned below was George B. Cox, a saloonkeeper who ran Cincinnati’s Republican political machine, which Ohioan William Howard Taft called a “local despotism” for the benefit of big corporations.

Religious Bigotry, Ethnic Hatred and Lynch Mobs

“Between 1830 and 1840 the population grew by 85 percent, reaching 46,338 residents, and made Cincinnati the fastest-growing city in America, sixth in population and third in manufacturing. In the 1830s and 1840s, Cincinnati’s population was composed mainly of native-born Americans from the Eastern Middle Atlantic and Upper Southern States.

Travel writers described it as a Yankee city with a pleasant blend of Southern ease and charm. But a new ethnic element appeared in the Thirties, when people from the fragmented states of Germany discovered Cincinnati.

Many of them clustered north of the canal in an area that they called Over-the-Rhine, where they built churches, houses, tenements (street-level shops with residence above), and small commercial buildings.

The new Whig party, intellectual successors to the Federalists, advocated government funding of “internal improvements,” primarily canals, highways and railroads . . . (Southern and eastern-based Jacksonians opposed federal funding for sectional projects that would chiefly benefit Kentucky, Ohio and the “West.” By the 1850s, entrepreneurial railroads radiated out from five depots in downtown Cincinnati like spokes on a half-broken wheel.

From 1835, German-speaking people were coming to Cincinnati in large numbers. The first were predominantly Protestants and Freethinkers, but Roman Catholics soon outnumbered them. By 1840, one-third of Cincinnati’s 75,000 citizens were German-speaking, of which an estimated two-thirds to three-fourths were Roman Catholic. The Irish . . . were also arriving in considerable numbers after 1840 . . .

As their numbers grew, so did hostility from the native-born majority. The Nativist riots of the 1840s and the political activities of the Know-Nothing party in the 1850s were indicative of the continuing bigotry toward Catholics and immigrants. In the 1870s and 1880s . . . Native-born Americans often blamed poor pay and labor conditions on the surplus of recent immigrants and freedmen. Social and political tensions grew over issues of class, race, ethnicity and criminal justice.

The city had a record of street violence, but there was no precedent for the Cincinnati Courthouse Riot of 1884, one of the bloodiest riots in American history. What began as a meeting in Music Hall . . . to discuss corruption in the justice system (a bribed jury had found a confessed murderer guilty of manslaughter only) ended with a lynch mob engaging law enforcement officials in a three-day street battle.”

After the riot, Cincinnati turned to George “Boss” Cox to stabilize city government.”

The American Founders foresaw the problem of abuse of power and the rise of a president who would cut the shackles of the Constitution, though they more feared sectionalism and an evil combination of the branches of government.

The abuse of power arose with a president who fomented war upon a State, which is treason under the Constitution, raised an army without the consent of Congress, and threatened to arrest and imprison all who defied him. With the formerly federal government afterward under absolute executive and congressional control, the schools educating young citizens on their fealty to national power.

James Louis Petrigu (1789-1863) was a South Carolina Unionist and served as that State’s attorney-general. His stated faith in education as the bulwark of a republic was unfortunately upset by government control of the schools.

“Who Shall Restrain the Will of the People?”

“As Petigru understood it, the United States Constitution confirmed what the Revolution had aimed to achieve. Reversing the Confederation’s dispersal of power was but a minor part of its accomplishment, for it had by its division of legitimate governmental power between the individual States and the federal union ensured the Revolution’s goals of restricting centralized public authority in the interests of individual liberty.

But individual freedom, as Petigru said in his 1844 Fourth of July oration, required positive government as well as restraints on legitimate power. This too the Constitution had accomplished with its system of checks and balances. Without both the powers allotted and the restraints imposed, “there would be no barrier between a dominant majority and the object they mean to effect.”

Thus, by creating a constitutional union that divided sovereignty between State and nation and checked the evil of concentrated power in any one branch of government, the American people had fulfilled the promise of their revolution.

But the problem of abuse of power was not obviated by the broadly democratic underpinning of the American experiment. Nowhere did Petigru more clearly address that dilemma than in the question he asked that Independence Day audience: “For who shall control where all are equal, or how shall the people restrain the will of the people?”

The best means to control the popular passions implied in his question was education. If a republic was to survive, he thought, its government must provide the schools necessary to cultivate in all its citizens the intellectual independence that was “the bright side of Democracy.”

Without access to knowledge, citizens would lack the ability to challenge their government, and individuals the means to protect their freedom . . . [and] withstand the force of majority opinion. And given Petigru’s opinion that “the Majority are wicked is a truth that passed long ago into a proverb,” republican government could not long survive unless it sponsored that learning, for “what hope is there for the human race when there is no minority?”

(James Louis Petigru: Southern Conservative, Southern Dissenter, William & Jane Pease, University of Georgia Press, 1995, excerpts pp. 149-150)

Lincoln supported the Corwin Resolution of 1860 which stated that “No amendment shall be made to the Constitution which will authorize or give to Congress the power to abolish or interfere, within any State, with the domestic institutions thereof, including that of persons held to labor or service by the laws of said State.”

His Republican party was “antislavery” only in regard to restricting black persons to the borders of the Southern States where they reside, and maintaining the territories of the West to the immigrants who supported his party.

After the secession of Southern States and his war against them begun, he offered protection for African slavery if they would return to his Union before January 1, 1863. When those States continued to fight for their independence, his total war pressed onward and the South’s economic wealth and political liberty was destroyed.

No Negotiation, No Compromise

“In the tumultuous six months between his election in November 1860 and the outbreak of the Civil War in April 1861, Abraham Lincoln rejected all diplomatic efforts to resolve the deepening crisis peacefully.

In the political dispute with the newly-constituted, but militarily weak, Confederate States of America, there would be no meaningful negotiations. No compromise would be offered or accepted. Instead, tensions between the two governments would be heightened, and the passions of the American public inflamed, by Lincoln’s provocative and deceptive rhetoric.

Lincoln’s words were a reflection of his unflagging desire to wage total war upon the South. It was to be a war that would last until the enemy agreed to unconditional surrender and US public officials and private contractors had made a financial killing. In 1878, Henry S. Wolcott, special investigator for the US War and Navy Departments, estimated “at least twenty, if not twenty-five percent of the entire expenditures of the government during the Rebellion, were tainted with fraud.”

Lincoln’s ideological view of politics equated progress and patriotism with support for a high protective tariff, internal improvements, and a national bank. Capturing just 39 percent of the popular vote, Lincoln considered his election a democratic mandate to pursue his agenda. A rejection of his economic program by the political leadership of the South, therefore, would be a rejection of democracy.

Lincoln’s program depended on the tariff, and the tariff depended on the South remaining in the Union, as did the survival of the Republican party. For that reason, Lincoln initially pledged his support for the Corwin Resolution, which had been adopted in the waning days of the Buchanan administration. This was the original Thirteenth Amendment to the Constitution.

It had been passed by the House and the Senate, and signed by President Buchanan, but it was never ratified, because, by then, many Southern States had decided to secede. The fact that the South withdrew from the Union despite the passage of this amendment indicated other issues besides slavery motivated their secession. Foremost was the South’s embrace of free trade, the antithesis of Lincoln’s economic agenda.”

(Lincoln, Diplomacy and War, Joseph E. Fallon, Chronicles, April 2008, excerpts pg. 43)

After the British themselves, New Englanders were responsible for populating the colonies with slaves purchased from African tribes, and the invention of Massachusetts tinkerer Eli Whitney in 1793 sent demand for slaves and cotton soaring.

With the election of Thomas Jefferson in 1800, New England Federalists unhappy with the new political supremacy of Virginia called upon the North “to combine to protect the commercial interests against the vicious slave-holding democrats of the South.” Thus began the descent into war between the sections.

Inheritors of Britain’s Colonial Labor System

“Slavery was disappearing from the North. The rector of the Swedish churches in America told the American Philosophical Society that the introduction of “mechanism” in the Southern States would eliminate the need of slaves; but the invention of the cotton gin led to the opposite result.

Defenders of slavery declared it was a necessary evil that would eventually cure itself. The slaveholder could not be held guilty of crime because slavery as a very common thing is due to the state of society, for which the slaveholder is not responsible. Slavery in America is preferable to liberty in Africa because the slave gets better care and acquires the Christian religion.

In fact, the underlying reasons for importing slaves is to further the Christian religion. Respectably opponents, generally in New England, questioned the argument that slavery is a curse of society, not of the individual. It is no more valid, they said, than the notion of drunkenness and adultery are not delinquencies of the individual. The greatest evil is that the slaves will eventually outnumber the whites, and this must lead either to the most horrible event, intermarriage, or the destruction of the whites.

For the most part, the critics looked for remedies in the abolition of the slave trade, the growth of voluntary manumission, and even the growth of trade and commerce with Africa in the manner pictured by [economist James] Swan. It was agreed that pecuniary considerations were the most important barrier to voluntary manumission, but the slaveholder was told to trust to the Lord for his recompense.

The general attitude was best expressed by the Baptist clergyman Samuel Jones of Philadelphia. The slave trade is abominable; the possession of slaves is not profitable except in the newly settled regions where the costs of labor are very high. But the slave owners are innocent inheritors of the institution and not obliged to free their slaves, “at least not until they have been fully reimbursed the full amount of their cost on equitable principles.”
