Douglas did not at first propose to repeal the Missouri Compromise. He intended to leave the question of slavery untouched. He did not want to reopen the agitation, which had been mostly quieted by the Compromise of 1850; but it soon became evident that if he were willing to leave the question in doubt, others were not. Dixon, of Kentucky, successor of Henry Clay in the Senate and a Whig in politics, offered an amendment to the bill proposing to repeal the Missouri Compromise outright. Douglas was rather startled when this motion was made. He went to Dixon's seat and begged him to withdraw his amendment, urging that it would reopen the controversies settled by the Compromise of 1850 and delay, if not prevent, the passage of any bill to organize the new territory. Dixon was stubborn. He contended that the Southern people had a right to go into the new territory equally with those of the North, and to take with them anything that was recognized and protected as property in the Southern States. Dixon's motion received immediate and warm support in the South.

Two or three days later, Douglas decided to embody Dixon's amendment in his bill and take the consequences. His amended bill divided the territory in two parts, Kansas and Nebraska. The apparent object of this change was to give the Missourians a chance to make the southernmost one a slave state; but this intention has been controverted by Douglas's friends in recent years, who have brought forward a mass of evidence to show that he had other sufficient reasons for thus dividing the territory and hence that it must not be assumed that he intended that one of them should be a slave state. The evidence consists of a record of efforts put forth by citizens of western Iowa in 1853-54 to secure a future state on the opposite side of the Missouri River homogeneous with themselves, and to promote the building of a Pacific railway from some point near Council Bluffs along the line of the Platte River. These efforts were heartily seconded by Senators Dodge and Jones and Representative Henn, of Iowa. They labored with Douglas and secured his coöperation. So Douglas himself said when he announced the change in the bill dividing the territory into two parts.

Most people at the present day, including myself, would be glad to concur with this view, but we must interpret Douglas's acts not merely by what he said in 1854, but also by what he said and did afterwards. In 1856 he made an unjustifiable assault upon the New England Emigrant Aid Company, for sending settlers to Kansas, as they had a perfect right to do under the terms of the bill; and he apologized for, if he did not actually defend, the Missourian invaders who marched over the border in military array, took possession of the ballot boxes, elected a pro-slavery legislature, and then marched back boasting of their victory. Troubles multiplied in Douglas's pathway rapidly after he introduced his Nebraska Bill, and it is very likely that an equal division of the territory between the North and South seemed to him the safest way out of his difficulties. That was the customary way of settling disputes of this kind. We need not assume, however, that he intended to do more than give the Missourians a chance to make Kansas a slave state if they could, for Douglas was not a pro-slavery man at heart.

Senator Thompson, of Kentucky, once alluded to the division of the territory embraced in the original Nebraska Bill into two territories, Kansas and Nebraska, showing that his understanding was that one should be a free state and the other a slave state, if the South could make it such. He said:

When the bill was first introduced in 1854 it provided for the organization of but one territory. Whence it came or how it came scarcely anybody knows, but the senator from Illinois (Mr. Douglas) has always had the credit of its paternity. I believe he acted patriotically for what he thought best and right. In a short time, however, we found a provision for a division—for two territories—Nebraska, the larger one, to be a free state, and as to Kansas, the smaller one, repealing the Missouri Compromise, we of the South taking our chance for it. That was certainly a beneficial arrangement to the North and the bill was passed in that way.[16]

What were Douglas's reasons for repealing the Missouri Compromise? It was generally assumed that he did it in order to gain the support of the South in the next national convention of the Democratic party. In the absence of any other sufficient motive, this will probably be the verdict of posterity, although he always repelled that charge with heat and indignation. A more important question is whether there would have been any attempt to repeal it if Douglas had not led the way. This may be safely answered in the negative. The Southern Senators did not show any haste to follow Douglas at first. They generally spoke of the measure as a free-will offering of the North, both Douglas and Pierce being Northern men, and both being indispensable to secure its passage. Francis P. Blair, of Missouri, a competent witness, expressed the opinion that a majority of the Southern senators were opposed to the measure at first and were coerced into it by the fear that they would not be sustained at home if they refused an advantage offered to them by the North.[17]

The Nebraska Bill passed the Senate by a majority of 22, and the House by a majority of 13. The Democratic party of the North was cleft in twain, as was shown by the division of their votes in the House: 44 to 43. The bill would have been defeated had not the administration plied the party lash unmercifully, using the official patronage to coerce unwilling members. In this way did President Pierce redeem his pledge to prevent any revival of the slavery agitation during his term of office.

When the bill actually passed there was an explosion in every Northern State. The old parties were rent asunder and a new one began to crystallize around the nucleus which had supported Birney, Van Buren, and Hale in the elections of 1844, 1848, and 1852. Both Abraham Lincoln and Lyman Trumbull were stirred to new activities. Both took the stump in opposition to the Nebraska Bill.

Trumbull was now forty-one years of age. He had gained the confidence of the people among whom he lived to such a degree that his reëlection to the supreme bench in 1852 had been unanimous. He now joined with Gustave Koerner and other Democrats in organizing the Eighth Congressional District in opposition to Douglas and his Nebraska Bill. Although this district had been originally a slaveholding region, it contained a large infusion of German immigration, which had poured into it in the years following the European uprising of 1848. Of the thirty thousand Germans in Illinois in 1850, Reynolds estimated that fully eighteen thousand had settled in St. Clair County. These immigrants had at first attached themselves to the Democratic party, because its name signified government by the people. When, however, it became apparent to them that the Democratic party was the ally of slavery, they went over to the opposition in shoals, under the lead of Koerner and Hecker. Koerner was at that time lieutenant-governor of the state, and his separation from the party which had elected him made a profound impression on his fellow countrymen. Hecker was a fervid orator and political leader, and later a valiant soldier in the Union army.

The Eighth Congressional District then embraced the counties of Bond, Clinton, Jefferson, Madison, Marion, Monroe, Randolph, St. Clair, and Washington. It was the strongest Democratic district in the state, but political parties had been thrown into such disorder by the Nebraska Bill that no regular nominations for Congress were made by either Whigs or Democrats. Trumbull announced himself as an anti-Nebraska Democratic candidate. He had just recovered from the most severe and protracted illness of his life and was in an enfeebled condition in consequence, but he made a speaking campaign throughout the district, and was elected by 7917 votes against 5306 cast for Philip B. Fouke, who ran independently as a Douglas Democrat. This victory defeated so many of the followers of Douglas who were candidates for the legislature that it became possible to elect a Senator of the United States in opposition to the regular Democracy.
