The veteran statesman who did so much in this cause, weaving its golden thread into the tissue of his renown, dwelt on it with pride, and accepted for his country the primacy that had been awarded. Never, in his extended Parliamentary career, did Lord Palmerston rise to a higher mood,—not even when claiming for Englishmen all the immunities of Roman citizenship,—Civis Romanus sum,—than when he pictured the dependence of Africans on their constant friend. “If ever,” said he, “by the assault of overpowering enemies, or by the errors of her misguided sons, England should fall, and her star should lose its lustre, with her fall, for a long period of time, would the hopes of the African, whether in his own continent or in the vast regions of America, be buried in the darkness of despair. I know well that in such case Providence would in due course of time raise up some other nation to inherit our principles and to imitate our practice; but, taking the world as it is, and states as they are constituted, I do not know—and I say it with regret and with pain—I do not know any nation that is now ready in this respect to supply our place.”[97] And can it be that now, instead of the African, a rebellion inspired by Slavery turns to England with hope?

The honorable story of British intervention against Slavery is incomplete without showing how its generous ardor broke forth against our Republic, which was denounced as linked with Slavery. Literature, eloquence, and poetry lent themselves to expose the terrible inconsistency. Lord Russell stepped aside from the easy path of biography, to declare that among us “oxen and horses are better treated than the men and women of African blood,” and then to proclaim “the cry of outraged humanity,” “the current of human sympathy,” and “the decrees of Eternal Justice,” irresistible.[98] Lord Macaulay, in the House of Commons, thundered forth: “The Government of the United States has formally declared itself the patron, the champion, of Negro Slavery all over the world, the evil genius, the Arimanes, of the African race, and seems to take pride in this shameful and odious distinction.… They put themselves at the head of the slave-driving interest throughout the world, just as Elizabeth put herself at the head of the Protestant interest; and wherever their favorite institution is in danger, are ready to stand by it as Elizabeth stood by the Dutch.”[99] Thomas Campbell, fresh from writing “Ye Mariners of England” and “Hohenlinden,” struck at our Slavery in most scornful verses on the national flag:—

“But what’s the meaning of the stripes?

They mean your negroes’ scars!”[100]

If these things, so bitterly said, were true, if Campbell, Macaulay, and Russell were right in their indignant rebuke, if Palmerston was justified in his eloquent pride, then must England make haste to turn away from a rebellion which seeks to reverse that noble intervention where the liberty of the African was a constant guide.


Here I close the historic instances illustrating the right and practice of foreign intervention. The whole subject is seen in these instances, teaching clearly what to avoid and what to follow. In this way, the Law of Nations, like History, gives its best lessons. For the sake of plainness, I gather up some of the conclusions.


Foreign intervention is armed or unarmed, although sometimes the two are not easily distinguishable. Unarmed intervention may have in it the menace of arms, or it may be war in disguise. When this is the case, it must be treated accordingly.

Armed intervention is war, and nothing less. Of course it can be vindicated only as war, and it must be resisted as war. Believing, as I do most profoundly, that war can never be a game, but must always be a crime when it ceases to be a duty,—a crime to be shunned, if not a duty to be performed swiftly and surely,—and that a nation, like an individual, is not permitted to take the sword except in just self-defence,—I find the same limitation in armed intervention, which becomes unjust invasion in proportion as it departs from just self-defence. Under this head is naturally included all that intervention moved by a tyrannical or intermeddling spirit, because such intervention, whatever its professions, is essentially hostile,—as when Russia, Prussia, and Austria partitioned Poland, when the Holy Alliance intermeddled everywhere and menaced even America, or when Russia intervened to crush the independence of Hungary, or France to crush the Roman Republic. All such intervention is inexcusable, illegal, and scandalous. Its vindication is found only in the effrontery that might makes right.
