Many viewed William H. Seward’s “higher law” speech treasonous as it claimed “laws” which superseded the United States Constitution – the compact agreed to by all the States as the law of the land. In reality, the abolitionists who sought a separation from what they referred to as “a covenant with Hell,” and unstable theorists like Seward, were the disunionists in 1860.

Higher Law Treason

“[Future President] Franklin Pierce addressed a Union meeting in Manchester [New Hampshire] in November 1850. His speech reveals his true sentiments on the most important issue of his time. When several Baptist ministers “hissed” at his remarks in favor of the Union, Pierce responded that the “feeble demonstration of moral treason to the Union, to humanity, to the cause of civil liberty would disturb neither him nor the meeting.” He declared, “If we are precipitated into a war by fanaticism, we cannot conquer. Both sections of the country may be immolated. Neither could come out of the contest short of ruin.”

Pierce was consistent in believing the preservation of the Union was more important than any one issue. The New Hampshire Patriot reported Pierce’s speech: “Who did not deplore slavery? But what sound-thinking mind regarded that as the only evil which could rest upon the land? The [abolitionist] men who would dissolve the Union did not deplore slavery any more than he did . . . The resort to disunion as an experiment to get rid of a political evil, would be about as wise as if a man were to think of remedying a broken arm by cutting his head off.” Pierce closed with the shout, “The Union! Eternal Union!”

When Senator Seward of New York followed [Daniel] Webster’s [7 March 1850] speech with one in which he declared that there is a “higher law” than the Constitution and that God was opposed to slavery, the Patriot editorialized, “If Mr. Seward’s doctrine were to be endorsed by the people at large there would be an end not only of the Union but of every rational form of government”. . . Webster would later call the “higher law” doctrine “Treason, treason, treason!”

(Franklin Pierce: New Hampshire’s Favorite Son, Peter A. Wallner, Plaidswede Publishing, 2004, pp. 168-169)

Henry Clay, the “great compromiser,” pleaded with abolitionists to cease their incendiary activities which threatened to disrupt the Union in a speech before the United States Senate in February 1839. The States he labels as “free” were former slave and slave trading States which were offering no peaceful and practical solutions to the African slavery they greatly helped nurture and perpetuate.

The Abolitionists Mad and Fatal Course

“ . . . Abolition should no longer be regarded as an imaginary danger. The abolitionists, let me suppose, succeed in their present aim of uniting the inhabitants of the free States, as one man, against the inhabitants of the slave States. Union on one side will beget union on the other.

And this process of reciprocal consolidation will be attended with all the violent prejudices, embittered passions, and implacable animosities, which ever degraded or deformed human nature. A virtual dissolution of the Union will have taken place, while the forms of its existence remain.

The most valuable element of union, mutual kindness, the feelings of sympathy, the fraternal bonds, which now happily unite us, will have been extinguished for ever.

One section will stand in menacing and hostile array against the other. The collision of opinion will be quickly followed by the clash of arms. I will not attempt to describe scenes which now happily lie concealed from our view. Abolitionists themselves would shrink back in dismay and horror at the contemplation of desolated fields, conflagrated cities, murdered inhabitants, and the overthrow of the fairest fabric of human government that ever rose to animate the hopes of civilized man.

Nor should these abolitionists flatter themselves that, if they can succeed in uniting the people of the free States, they will enter the contest with a numerical superiority that must insure victory. All history and experience proves the hazard and uncertainty of war. And we are admonished by Holy Writ, that the race is not to the swift, nor the battle to the strong. But if they were to conquer, whom would they conquer?

A foreign foe – one who had insulted our flag, invaded our shores, and laid our country waste? No, sir; no, sir. It would be a contest without laurels, without glory; a self, a suicidal conquest; a conquest of brothers over brothers, achieved by one over another portion of the descendants of common ancestors, who, nobly pledging their lives, their fortunes, and their sacred honor, had fought and bled, side by side, in many a hard battle on land and ocean, severed our country from the British crown, and established our original independence.

The inhabitants of the slave States are sometimes accused by their Northern brethren with displaying rashness and sensibility to the operations and proceedings of the abolitionists.

[But] Let me suppose that the people of the slave States were to form societies, subsidize presses, make large pecuniary contributions, send forth numerous missionaries throughout all their borders, and enter into machinations to burn the beautiful capitals, destroy the productive manufactories, and sink in the ocean the gallant ships of the Northern States. Would these incendiary proceedings be regarded as neighborly and friendly, and consistent with the fraternal sentiments which should ever by cherished by one portion of the Union toward the another?

Would they excite no emotion? Occasion no manifestations of dissatisfaction? Nor lead to any acts of retaliatory violence?

I beseech the abolitionists themselves, solemnly to pause in their mad and fatal course . . . let them select some one more harmless, that does not threaten to deluge our country in blood. I entreat that portion of my countrywomen, who have given their countenance to abolition, to . . . reflect that the ink which they shed in subscribing with their fair hands abolition petitions, may prove but the prelude to the shedding of the blood of their brethren.

I adjure all the inhabitants of the free States to rebuke and discountenance, by their opinion and their example, measures which must inevitably lead to the most calamitous consequences.”

(The South, A Documentary History, Ina Woestemeyer Van Noppen, D. Van Nostrand Company, 1958, pp. 258-260)

Robert Hayne of South Carolina followed Jefferson’s admonition that the national debt was not something to be passed on to future generations; it was considered immoral for a president not to pay the debts incurred under their administrations before leaving office. In encouraging an unending public debt, Daniel Webster, on the other hand, Webster was promoting the American System of Whig politician Henry Clay which would give the government an endless supply of money with which to buy influence and power.

Bernhard Thuersam, www.circa1865.org

Spending the Money of Future Generations

“The gentleman from Massachusetts (Webster), in alluding to a remark of mine that before any disposition could be made of the public lands, the national debt (for which they stand pledged) must be first paid, took occasion to intimate (that Southerners desire to pay the national debt) “arises from a disposition to weaken the ties which bind the people to the Union.”

But, adds he gentleman, “so far as the debt may have an effect in binding the debtors to the country, and thereby serving as a link to hold the States together, he would be glad that it should exist forever.” Surely then, sir, on the gentleman’s own principles, he must be opposed to the payment of the debt.

Sir, let me tell that gentleman that the South repudiates the idea that a pecuniary dependence on the Federal Government is one of the legitimate means of holding the States together. A monied interest in the Government is essentially a base interest . . . it is opposed to all the principles of free government and at war with virtue and patriotism. In a free government, this principle of abject dependence if extended through all the ramifications of society must be fatal to liberty. Already we have made alarming strides in that direction.

The entire class of manufacturers, the holders of stocks with their hundreds of millions in capital, are held to the Government by the strong link of pecuniary interests; millions of people, entire sections of the country, interested, or believing themselves to be so, in the public lands and the public treasure, are bound to the Government by the expectation of pecuniary favors.

If this system is carried on much further, no man can fail to see that every generous motive of attachment to the country will be destroyed, and in its place will spring up those low, groveling, base and selfish feelings which bind men to the footstool of despots by bonds as strong and as enduring as those which attach them to free institutions.”

(The Webster-Hayne Debate on the Nature of the Union, Herman Belz, Editor, Liberty Fund, 2000, pp. 42-43. Speech of Robert Y. Hayne of South Carolina, January 25, 1830)

James Redpath was a determined abolitionist and author of many Northern newspaper articles damning slavery. Also a determined revolutionist, he later admitted that he “endeavored, personally and by my pen, to precipitate a revolution” in 1855 Kansas. His writings worshipped the fanatic John Brown and he specialized in sending Horace Greeley lurid accounts of flesh-creeping atrocities by barbaric Southerners in Kansas. Redpath, like Lincoln and many abolitionists, despised African slavery but wanted freedmen relocated elsewhere.

Haitian Emigration Encouraged

“The government of Haiti actively encouraged the emigration of American Negroes. Immigrants were promised a homestead, tools for working the land, and food and shelter from the time they arrived on the island until they had managed to get settled. But above all Haiti promised a homeland for Afro-Americans.

As the General Agent of emigration to Haiti, James Redpath — the American abolitionist — wrote in his “Guide to Hayti,” “Pride of race, self-respect, social ambition, parental love, the madness of the South, the meanness of the North, the inhumanity of the Union, and the inclemency of Canada — all say to the Black and the man of color, Seek elsewhere a home and a nationality.” Hundreds of refugees from both the North and South went to Haiti, including some from Charleston. But once there they had a hard time getting the government to deliver on any of its promises.”

(No Chariot Let Down, Johnson & Roark, editors, UNC Press, 1984)

Poor Alexander H. Stephens!

The Vice President of the American Confederacy’s informal speech to a Savannah audience in March 1861 is used to verify that the defense of slavery is all the new experiment in American government was about — and despite the fact that Stephen’s remarks were simply imperfect reporter’s notes and we are not even sure if he uttered those exact words.

If Stephen’s indeed mentioned “cornerstone and African slavery” in the same sentence in Savannah, he most likely was referring to Charleston abolitionist Angelina Grimke’ who some 25 years before said this about the United States.

Angelina’s speech in 1836 was entitled “An Appeal to the Christian Women of the South” and its topic anti-slavery. Both she and her sister were born into wealth in Charleston, SC — and later moved to the former center of the transatlantic slave trade, New England, to become Quakers and join William Lloyd Garrison’s abolition movement. There the Grimke’ sisters perhaps not only engaged in serious abolitionist discourse but also discovered that the slavery they abhorred was a mostly New England enterprise, and supported by its notorious rum trade with Africa.

Grimke stated in her appeal that “The interests of the North . . . are very closely combined with those of the South. The Northern merchants and manufacturers are making their fortunes out of the produce of slave labor . . . [and] the North is most dreadfully afraid of Amalgamation. She is alarmed at the very idea of a thing so monstrous, as she thinks. And lest this consequence might flow from emancipation, she is determined to resist all efforts at emancipation without expatriation. It is not because she [the North] approves of slavery, or believes it to be “the cornerstone of our republic,” for she is as much anti-slavery as we are; but amalgamation is too horrible to think of.” (see “Against Slavery, An Abolitionist Reader,” Angelina & Sarah Moore Grimke’, Penguin Books, 2000).

Stephen’s wrote in his Recollection’s that he spoke extemporaneously in his Savannah speech, and the reporter’s notes he reviewed afterward “were imperfect” contained “glaring errors.” He goes on to explain the contents of his speech with “The relation of the black to the white race, or the proper status of the colored population amongst us, was a question now of vastly more importance than when the Constitution was formed. The order of subordination is nature’s great law; philosophy taught that order as the normal condition of the African amongst European races. Upon this recognized principle of a proper subordination, let it be called slavery or what not, our State institutions were formed and rested. The principle of the subordination of the inferior to the superior was the “cornerstone” on which it was formed. I used this metaphor merely to illustrate the firm convictions of the framers of the new Constitution that this relation of the black to the white race, which existed in 1787 . . . The status of the African race in the new Constitution was left just where it was in the old; I affirmed and meant to affirm nothing else in this Savannah speech” (Recollections of  Alexander H. Stephens, 1910/1998, LSU Press).

Thus Stephens viewed African slavery in the same way as the abolitionists who sought secession from the United States by New England, to separate themselves from what they saw as the evil cornerstone of the United States. And the Confederacy incorporated nothing more than what the United States already had recognized as a domestic institution of the States, to be accepted or eradicated in time by each State.  This raises the obvious question: If the abolitionists were opposed to slavery, why did they not advance a peaceful and practical emancipation proposal as did England in the 1840s with compensated emancipation?

The peaceful political separation desired by the American South in early 1861 was best summarized by President Jefferson Davis’ in his inaugural address: “We seek no conquest, no aggrandizement, no concession of any kind from the States with which we were lately confederated. All we ask is to be let alone; that those who never held power over us shall not now attempt our subjugation by arms.”

One American Ruler to Enforce Obedience

“From Mr. [Robert] Toombs, Secretary of State, Message No. 5, Department of State, Montgomery, Alabama, May 18, 1861.

To: Hon Wm. L. Yancey, Hon. Pierre A. Rost, Hon. A. Dudley Mann, Commissioners of the Confederate States, etc.

Gentlemen: My dispatch of the 24^th ultimo contained an accurate summary of the important events which had transpired up to that date, and informed you that the Executive of the United States had commenced a war of aggression against the Confederate States.

On the 20^th instant the convention of the people of North Carolina will assemble at Raleigh, and there is no doubt that, immediately thereafter, ordinances of secession from the United States, and union with the Confederate States, will be adopted.

Although ten independent and sovereign States have thus deliberately severed the bonds which bound them in political union with the United States, and have formed a separate and independent Government for themselves, the President of the United States affects to consider that the Federal Union is still legally and constitutionally unbroken . . . He claims to be our ruler, and insists that he has the right to enforce our obedience.

From the newspaper press, the rostrum, and the pulpit, the partisans of Mr. Lincoln, while they clamorously assert their devotion to the Union and Constitution of the United States, daily preach a relentless war between the sections, to be prosecuted not only in violation of all constitutional authority, but in disregard of the simplest law of humanity.

The authorized exponents of the sentiments of [Lincoln’s party] . . . avow that it is the purpose of the war to subjugate the Confederate States, spoliate the property of our citizens, sack and burn our cities and villages, and exterminate our citizens . . .

[The] real motive which actuates Mr. Lincoln and those who now sustain his acts is to accomplish by force of arms that which the masses of the Northern people have long sought to effect – namely, the overthrow of our domestic institutions, the devastation and destruction of our social interests, and the reduction of the Southern States to the condition of subject provinces.

It is not astonishing that a people educated in that school which always taught the maintenance of the rights of the few against the might of the many, which ceaselessly regarded the stipulation to protect and preserve the liberties and vested rights of every member of the Confederacy as the condition precedent upon which each State delegated certain powers necessary for self-protection to the General Government, should refuse to submit dishonorably to the destruction of their constitutional liberty, the insolent denial of their right to govern themselves and to hold and enjoy their property in peace.

In the exercise of that greatest of the rights reserved to the several States by the late Federal Constitution – namely, the right for each State to be judge for itself, as well of the infractions of the compact of the Union, as of the mode and measure of redress – the sovereignties composing the Confederate States resolved to sever their political connection with the United States and form a Government of their own, willing to effect this purpose peacefully at any sacrifice save that of honor and liberty, but determined even at the cost of war to assert their right to independence and self-government.”

(A Compilation of the Messages and Papers of the Confederacy 1861-1865, James D. Richardson, Volume II, US Publishing Company, 1905, excerpt, pp. 26-31)

The violent attack of John Brown at Harper’s Ferry “and his apotheosis by Northern abolitionists had struck fear and rage into the hearts of Southerners and had revived talk of secession that had all but died out in 1859.” This sad event all but confirmed the suspicion of many Southerners that the North wished to destroy the South, and the Union.

Bernhard Thuersam, www.circa1865.org

John Brown and His Greater Villains

“On Wednesday morning, October 19, John Brown and [Aaron Dwight] Stevens were placed in a wagon and driven to the railway station under a strong guard of Marines to protect them from the possibility of a merciful lynching.

But when they reached the waiting train and the shouts of “Lynch them, lynch them!” rose, the Governor was there to call back, “Oh, it would be cowardly to do so now!”  The Sheriff of Jefferson County and the United States Marshal for the Western District of Virginia committed their four prisoners to the jail at Charlestown to await trial.

There was no apparent reason why the prisoners should not be brought to justice as soon as possible, for the evidence was clear, the law demanded immediate trial, and the State of Virginia recognized no advantage in submitting the case to the Federal courts. The Federal government was directly [affected] by the attack on the arsenal and indirectly by the whole nature of the conspiracy, but Virginia was insisting on a primary principle in retaining jurisdiction.

In the case of John Brown himself there was little hesitation; in that of his companions more debate occurred, for the temptation was strong to embody in fact a subsidiary principle concerning the slave problem by turning Stevens over to the Federal Government for prosecution . . . the great advantage the Federal court possessed [was] being able to summon “the greater villains” who resided beyond the jurisdiction of the State of Virginia; and meanwhile some of these villains had made haste to reside beyond the jurisdiction of the United States.

The immediate trial and the wounds of two of the prisoners provided unexpected capital for the “liberal” newspapers in the North. At first the Republican press hurried to repudiate John Brown and all his works, for it was felt that this sort of thing might prove disastrous in the Presidential contest of the next year, but it was not long before editors and politicians alike recognized an opportunity in the situation.

The Chicago Convention which nominated Abraham Lincoln in 1860 unanimously resolved that the attempt of John Brown was criminal . . . But in the autumn of 1859 the “liberal” press . . . deplored the conditions which made [Brown’s attack] necessary; it deplored the misguided effort in a holy cause, but abhorred the barbarous conduct in Virginia in suppressing that effort. [William Lloyd] Garrison wrote in the Liberator:

“In recording the expressions of sympathy and admiration which are so widely felt for John Brown, whose doom is now swiftly approaching . . . that, judging him by the code of Bunker hill, we think he is deserving of high-wrought eulogy as any who ever wielded sword or battle-axe in the cause of liberty . . . ”

(John Brown, The Making of a Martyr, Robert Penn Warren, J.S. Sanders and Company, 1929, pp. 393-395)

While the Republican party reveled in its plurality victory and avoided any compromise in order to maintain party unity, Unionists like Jefferson Davis emulated great American leaders of earlier times in challenging Congress to meet the crisis and save the creation of the Founders.

Great Americans Amid a Great Crisis  

“Jefferson Davis, in his farewell address to the United States Senate, expressed the sentiments of Virginia . . . when he said:

“Now sir, we are confusing language very much. Men speak of revolution; and when they say revolution, they mean blood. Our fathers meant nothing of the sort. When they spoke of revolution, they meant the inalienable right.

When they declared as an inalienable right, the power of the people to abrogate and modify their form of government whenever it did not answer the ends for which it was established, they did not mean that they were to sustain that by brute force . . . Are we, in this age of civilization and political progress . . . are we to roll back the whole current of human thought and again return to the mere brute force which prevails between beasts of prey as the only method of settling questions between men?

Is it to be supposed that the men who fought the battles of the Revolution for community independence, terminated their great efforts by transmitting prosperity to a condition in which they could only gain those rights by force?  If so, the blood of the Revolution was shed in vain; no great principles were established; for force was the law of nature before the battles of the Revolution were fought.”

Robert E. Lee, writing on the 23rd of January, 1861, said:

“Secession is nothing but revolution. The framers of our constitution never exhausted so much labor, wisdom and forbearance in its formation and surrounded it with so many guards and securities if it was intended to be broken by every member of the Confederacy at will . . . Still, a Union that can only be maintained by swords and bayonets and in which strife and civil war are to take the place of brotherly love and kindness, has no charm for me. If the Union is dissolved and the Government disrupted, I shall return to my native State and share the miseries of my people — and save in defense (of Virginia) will draw my sword on none.”

George Baylor, speaking on the 1st of March 1861 in the Virginia Convention, said:

“I have said, Mr. President, that I did not believe in the right of secession. But whilst I make that assertion, I also say that I am opposed to coercion on the part of the Federal Government with the view of bringing the seceded States back into the Union . . . I am opposed to it first because I cannot find any authority in the Constitution of the United States delegating that power to the Federal Government, and second, because if the Federal Government had the power it would be wrong to use it.”

John Quincy Adams, speaking before the New York Historical Society in 1839, on the 50th Anniversary of Washington’s inauguration as President of the United States, said:

“To the people alone there is reserved as well the dissolving as the constituent power, and that power can be exercised by them only under the tie of conscience binding them to the retributive justice of Heaven.

With those qualifications we may admit the right as vested in the people of every State of the Union with reference to the General Government which was exercised by the people of the United Colonies with reference to the supreme head of the British Empire of which they formed a part, and under these limitations have the people of each State of the Union a right to secede from the Confederated Union itself.”

(Virginia’s Attitude Toward Secession, Beverley B. Munford, L.H. Jenkins, Richmond, VA, 1909, pp. 294-295)

It is said that antebellum Southern politics were for the most part honest and ruled by responsible statesmen, but Reconstruction forced Southern leaders to reluctantly descend into the mud to successfully oppose the carpetbaggers, Union Leagues and Radical Republicans. The high-toned sense of serving the public good was seen in statesman Jefferson Davis, who acted from conviction alone; William Seward was more interested in manipulating public opinion and serving his own twisted ends. The former tried his best to save the Union, the latter helped destroy it.

Bernhard Thuersam, www.circa1865.org

The Inscrutable William Seward

“It was on one of these visits that Mr. Seward said a most remarkable thing to me [Varina Davis]. We were speaking of the difficulty men generally had in doing themselves justice [when speaking in public], if not cheered on by the attention and sympathy of the audience. Mr. Seward said . . . ” it is rather a relief to me to speak to empty benches.”

I exclaimed, “Then, whom do you impersonate?” [Seward replied] “The [news]papers . . . I speak to the papers, they have a much larger audience than I, and can repeat a thousand times if need be what I want to impress upon the multitude outside; and then there is the power to pin my antagonists down to my exact words, which might be disputed if received orally.”

Another day he began to talk on the not infrequent topic among us, slavery . . . I said, “Mr. Seward, how can you make, with a grave face, those piteous appeals for the Negro that you did in the Senate; you were too long a schoolteacher in Georgia to believe the things you say?”

He looked at me quizzically, and smilingly answered: “I do not, but these appeals, as you call them, are potent to affect the rank and file of the North.”

Mr. Davis said, very much shocked by Mr. Seward’s answer, “But Mr. Seward, do you never speak from conviction alone?”  “Never,” answered he. Mr. Davis raised up his . . . head, and with much heat whispered, “As God is my judge, I never spoke from any other motive.”

After this inscrutable human moral, or immoral, paradox left us, we sat long discussing him with sincere regret, and the hope that he had been making a feigned confidence to amuse us. He [Seward] frankly avowed that truth should be held always subsidiary to an end, and if some other statement could sub serve that end, he made it. He said, again and again, that political strife was a state of war, and in war all stratagems were fair.

About this time Mr. Seward came forward into greater prominence, and became the most notable leader of the Republican party. Mr. [President James] Buchanan said: “He was much more of a politician than a statesman, without strong convictions; he understood the art of preparing in his closet and uttering before the public, antithetical sentences, well-calculated to both inflame the ardor of his anti-slavery friends and exasperate his pro-slavery opponents . . . he thus aroused passions, probably without so intending, which it was beyond his power to control.”

(Jefferson Davis, A Memoir By His Wife Varina, N&A Publishing, 1990, excerpts, pp. 580-652)

In his message to Congress on 29 April 1861, President Jefferson Davis cited the Northern threat to the South’s labor system as a cause of withdrawal from political union with the North. The murderous raid of John Brown in 1859 had convinced the South of the North’s violent intentions, which were supported by influential and wealthy men.

Indispensable African Slaves

“As soon . . . as the Northern States that prohibited African slavery within their limits had reached a number sufficient to give their representation a controlling voice in the Congress, a persistent and organized system of hostile measures against the rights of the owners of slaves in the southern States was inaugurated and gradually extended. A continuous series of measures was devised and prosecuted for the purpose of rendering insecure the tenure of property in slaves . . .

Senators and Representatives were sent to the common councils of the nation, whose chief title to this distinction consisted in the display of a spirit of ultra-fanaticism, and whose business was . . . to awaken the bitterest hatred against the citizens of sister States, by violent denunciation of their institutions; the transaction of public affairs was impeded by repeated efforts to usurp powers not delegated by the Constitution, for the purpose of . . . reducing those States which held slaves to a condition of inferiority.

In the meantime, the African slaves had augmented in number from about 600,000, at the date of the adoption of the constitutional compact, to upward of 4,000,000. In moral and social condition they had been elevated from brutal savages into docile, intelligent and civilized agricultural laborers, and supplied not only with bodily comforts but with careful religious instruction.

Under the supervision of a superior race, their labor had been so directed as not only to allow a gradual and marked amelioration of their own condition, but to convert hundreds of thousands of square miles of the wilderness into cultivated lands covered with a prosperous people; towns and cities had sprung into existence, and had rapidly increased in wealth and population under the social system of the South . . . and the productions of cotton, sugar, and tobacco, for the full development and continuance of which the labor of African slaves was and is indispensable, had swollen to an amount which formed nearly three-fourths of the exports of the whole United States and had become absolutely necessary to the wants of civilized man.

With interests of such overwhelming magnitude imperiled, the people of the Southern States were driven by the conduct of the North to the adoption of some course of action to avert the danger with which they were openly menaced.”

(The Causes of the Civil War, Kenneth M. Stampp, editor, Prentice-Hall Inc., 1965, pp. 134-135)
