The Republican party sprang into being to meet the overruling call of the hour. Then Abraham Lincoln's time was come. He rapidly advanced to a position of conspicuous championship in the struggle. This, however, was not owing to his virtues and abilities alone. Indeed, the slavery question stirred his soul in its profoundest depths; it was, as one of his intimate friends said, "the only one on which he would become excited"; it called forth all his faculties and energies. Yet there were many others who, having long and arduously fought the antislavery battle in the popular assembly, or in the press, or in the halls of Congress, far surpassed him in prestige, and compared with whom he was still an obscure and untried man. His reputation, although highly honorable and well earned, had so far been essentially local. As a stump-speaker in Whig canvasses outside of his State he had attracted comparatively little attention; but in Illinois he had been recognized as one of the foremost men of the Whig party. Among the opponents of the Nebraska Bill he occupied in his State so important a position, that in 1856 he was the choice of a large majority of the "Anti-Nebraska men" in the Legislature for a seat in the Senate of the United States which then became vacant; and when he, an old Whig, could not obtain the votes of the Anti-Nebraska Democrats necessary to make a majority, he generously urged his friends to transfer their votes to Lyman Trumbull, who was then elected. Two years later, in the first national convention of the Republican party, the delegation from Illinois brought him forward as a candidate for the vice-presidency, and he received respectable support. Still, the name of Abraham Lincoln was not widely known beyond the boundaries of his own State. But now it was this local prominence in Illinois that put him in a position of peculiar advantage on the battlefield of national politics. In the assault on the Missouri Compromise which broke down all legal barriers to the spread of slavery Stephen Arnold Douglas was the ostensible leader and central figure; and Douglas was a Senator from Illinois, Lincoln's State. Douglas's national theatre of action was the Senate, but in his constituency in Illinois were the roots of his official position and power. What he did in the Senate he had to justify before the people of Illinois, in order to maintain himself in place; and in Illinois all eyes turned to Lincoln as Douglas's natural antagonist.
As very young men they had come to Illinois, Lincoln from Indiana, Douglas from Vermont, and had grown up together in public life, Douglas as a Democrat, Lincoln as a Whig. They had met first in Vandalia, in 1834, when Lincoln was in the Legislature and Douglas in the lobby; and again in 1836, both as members of the Legislature. Douglas, a very able politician, of the agile, combative, audacious, "pushing" sort, rose in political distinction with remarkable rapidity. In quick succession he became a member of the Legislature, a State's attorney, secretary of state, a judge on the supreme bench of Illinois, three times a Representative in Congress, and a Senator of the United States when only thirty-nine years old. In the National Democratic convention of 1852 he appeared even as an aspirant to the nomination for the Presidency, as the favorite of "young America," and received a respectable vote. He had far outstripped Lincoln in what is commonly called political success and in reputation. But it had frequently happened that in political campaigns Lincoln felt himself impelled, or was selected by his Whig friends, to answer Douglas's speeches; and thus the two were looked upon, in a large part of the State at least, as the representative combatants of their respective parties in the debates before popular meetings. As soon, therefore, as, after the passage of his Kansas-Nebraska Bill, Douglas returned to Illinois to defend his cause before his constituents, Lincoln, obeying not only his own impulse, but also general expectation, stepped forward as his principal opponent.
Thus the struggle about the principles involved in the Kansas-Nebraska Bill, or, in a broader sense, the struggle between freedom and slavery, assumed in Illinois the outward form of a personal contest between Lincoln and Douglas; and, as it continued and became more animated, that personal contest in Illinois was watched with constantly increasing interest by the whole country. When, in 1858, Douglas's senatorial term being about to expire, Lincoln was formally designated by the Republican convention of Illinois as their candidate for the Senate, to take Douglas's place, and the two contestants agreed to debate the questions at issue face to face in a series of public meetings, the eyes of the whole American people were turned eagerly to that one point: and the spectacle reminded one of those lays of ancient times telling of two armies, in battle array, standing still to see their two principal champions fight out the contested cause between the lines in single combat.
Lincoln had then reached the full maturity of his powers. His equipment as a statesman did not embrace a comprehensive knowledge of public affairs. What he had studied he had indeed made his own, with the eager craving and that zealous tenacity characteristic of superior minds learning under difficulties.
