The Republican state convention had previously assembled on September 7 and selected a ticket, equally divided between men of Democratic and Whig antecedents, headed by Elias W. Leavenworth for secretary of state. Great confidence was felt in its election until the Americans met in convention on September 22 and indorsed five of its candidates and four Democrats. This, however, did not abate Republican activity, and, in the end, six of the nine Republican nominees were elected. The weight of the combined opposition, directed against Leavenworth, caused his defeat by less than fifteen hundred, showing that Republicans were gradually absorbing all the anti-slavery elements.

Upon what theory the American party nominated an eclectic ticket did not appear, although the belief obtained that it hoped to cloud Seward's presidential prospects by creating the impression that the Senator was unable, without assistance, to carry his own State on the eve of a great national contest. But whatever the reason, the result deeply humiliated the party, since its voting strength, reduced to less than 21,000, proved insufficient to do more than expose the weakness. This was the last appearance of the American party. It had endeavoured to extend its life and increase its influence; but after its refusal to interdict slavery in the territories it rapidly melted away. Henry Wilson, senator and Vice President, declared that he would give ten years of his life if he could blot out his membership in the Know-Nothing party, since it associated him throughout his long and attractive public career with proscriptive principles of which he was ashamed.

In the midst of the campaign the country was startled by John Brown's raid at Harper's Ferry. For two years Brown had lived an uneventful life in New York on land in the Adirondack region given him by Gerrit Smith. In 1851, he moved to Ohio, and from thence to Kansas, where he became known as John Brown of Osawatomie. He had been a consistent enemy of slavery, working the underground railroad and sympathising with every scheme for the rescue of slaves; but once in Kansas, he readily learned the use of a Sharpe's rifle. In revenge for the destruction of Lawrence, he deliberately massacred the pro-slavery settlers living along Pottawatomie creek. "Without the shedding of blood there is no remission of sins," was a favourite text. His activity made him a national character. The President offered $250 for his arrest and the governor of Missouri added $3000 more. In 1858, he returned East, collected money to aid an insurrection among the slaves of Virginia, and on October 17, 1859, with eighteen men, began his quixotic campaign by cutting telegraph wires, stopping trains, and seizing the national armory at Harper's Ferry. At one time he had taken sixty prisoners.

The affair was soon over, but not until the entire band was killed or captured. Brown, severely hurt, stood between two of his sons, one dead and the other mortally wounded, refusing to surrender so long as he could fight. After his capture, he said, coolly, in reply to a question: "We are Abolitionists from the North, come to release and take your slaves."

The trial, conviction, and execution of Brown and his captured companions ended the episode, but its influence was destined to be far-reaching. John Brown became idealised. His bearing as he stood between his dead and dying sons, his truth-telling answers, and the evidence of his absolute unselfishness filled many people in the North with a profound respect for the passion that had driven him on, while his bold invasion of a slave State and his reckless disregard of life and property alarmed the South into the sincere belief that his methods differed only in degree from the teachings of those who talked of an irrepressible conflict and a higher law. To aid him in regaining his lost position in the South, Stephen A. Douglas proclaimed it as his "firm and deliberate belief that the Harper Ferry crime was the natural, logical, and inevitable result of the doctrine and teachings of the Republican party."[223]

The sentimentalists of the North generally sympathised with Brown. Emerson spoke of him as "that new saint awaiting his martyrdom, and who, if he shall suffer, will make the gallows glorious like the cross."[224] In the same spirit Thoreau called him "an angel of light," and Longfellow wrote in his diary on the day of the execution: "The date of a new revolution, quite as much needed as the old one."[225] But the Republican leaders deprecated the affair, characterising it as "among the gravest of crimes," and denying that it had any relation to their party except as it influenced the minds of all men for or against slavery.

William H. Seward was in Europe at the time of the raid. Early in May, 1859, his friends had celebrated his departure from New York, escorting him to Sandy Hook, and leaving him finally amidst shouts and music, bells and whistles, and the waving of hats and handkerchiefs. Such a scene is common enough nowadays, but then it was unique. His return at the close of December, after an absence of eight months, was the occasion of great rejoicing. A salute of a hundred guns was fired in City Hall Park, the mayor and common council tendered him a public reception, and after hours of speech-making and hand-shaking he proceeded slowly homeward amidst waiting crowds at every station. At Auburn the streets were decorated, and the people, regardless of creed or party, escorted him in procession to his home. Few Republicans in New York had any doubt at that moment of his nomination and election to the Presidency.

On going to Washington Seward found the United States Senate investigating the Harper's Ferry affair and the House of Representatives deadlocked over the election of a speaker. Bitterness and threats of disunion characterised the proceeding at both ends of the Capitol. "This Union," said one congressman, "great and powerful as it is, can be tumbled down by the act of any one Southern State. If Florida withdraws, the federal government would not dare attack her. If it did, the bands would dissolve as if melted by lightning."[226] Referring to the possibility of the election of a Republican President, another declared that "We will never submit to the inauguration of a Black Republican President. You may elect Seward to be President of the North; but of the South, never! Whenever a President is elected by a fanatical majority of the North, those whom I represent are ready, let the consequences be what they may, to fall back on their reserved rights, and say, 'As to this Union we have no longer any lot or part in it.'"[227]

In the midst of these fiery, disunion utterances, on the 21st of February, 1860, Seward introduced a bill for the admission of Kansas into the Union. After the overwhelming defeat of the Lecompton Constitution, the free-state men had controlled the territorial legislature, repealed the slave code of 1855, and, in the summer of 1859, convened a constitutional convention at Wyandotte. A few weeks later the people ratified the result of its work by a large majority. It was this Wyandotte Constitution under which Seward proposed to admit Kansas, and he fixed the consideration of his measure for the 29th of February. This would be two days after Abraham Lincoln had spoken in New York City.

Lincoln, whose fame had made rapid strides in the West since his debate with Douglas in 1858, had been anxious to visit New York. It was the home of Seward, the centre of Republican strength, and to him practically an unknown land. Through the invitation of the Young Men's Central Republican Union he was now to lecture at Cooper Institute on the 27th of February. It was arranged at first that he speak in Henry Ward Beecher's church, but the change, relieving him from too close association with the great apostle of abolition, opened a wider door for his reception. Personally he was known to very few people in the city or State. In 1848, on his way to New England to take the stump, he had called upon Thurlow Weed at Albany, and together they visited Millard Fillmore, then candidate for Vice President; but the meeting made such a slight impression upon the editor of the Evening Journal that he had entirely forgotten it. Thirty years before, in one of his journeys to Illinois, William Cullen Bryant had met him. Lincoln was then a tall, awkward lad, the captain of a militia company in the Black Hawk War, whose racy and original conversation attracted the young poet; but Bryant, too, had forgotten him, and it was long after the famous debate that he identified his prairie acquaintance as the opponent of Douglas. Lincoln, however, did not come as a stranger. His encounter with the great Illinoisan had marked him as a powerful and logical reasoner whose speeches embraced every political issue of the day and cleared up every doubtful point. Well-informed people everywhere knew of him. He was not yet a national character, but he had a national reputation.
