Rivers of Conflict: The Consistent Containment: How Lincoln’s Unchanging Stance Fueled Southern Secession
Editor’s Note
In the last article, I explored how Lincoln’s understanding of the Constitution shaped him during his years as a lawyer. When he ran for the United States Senate in 1858, his legal beliefs faced their first major political test before the voters of Illinois.
That election brought Lincoln into the famous debates with Stephen A. Douglas. It also forced him to explain exactly what he believed the federal government could do about slavery.
This article is not written by a professional historian or academic expert. It is written by someone trying to better understand the political beliefs, fears, economic pressures, and divisions that shaped America before the Civil War.
The goal is not to tell people what to think.
The goal is to encourage people to look deeper.
The Political Line Lincoln Drew in 1858
Lincoln lost the Senate race to Stephen A. Douglas, but the debates made him a national political figure. More importantly, they placed his position on slavery in plain view.
Lincoln opposed the expansion of slavery into the western territories. At the same time, he repeatedly stated that he did not believe the federal government had the constitutional authority to abolish slavery in states where it already existed.
That position became known as “Free Soil.” It was not an immediate demand for emancipation throughout the country. It was a plan to prevent slavery from spreading into the territories that had not yet become states.
Lincoln’s argument depended on an important distinction. Existing states possessed authority over their domestic institutions. The federal government, however, had broad authority over the territories and over the process by which new states entered the Union.
Under this interpretation, Congress could restrict slavery in a territory before that territory became a state. A future state might then enter the Union without slavery, even if some settlers had wanted to preserve it in their state constitution.
To Lincoln, this was a constitutional argument. To many Southern leaders, it was a declaration that the federal government could control the future of slavery by controlling the future of the western territories.
What many modern readers do not realize is that Lincoln’s Free Soil position was also an assertion of federal authority over the territories. For that policy to work, Congress had to keep slavery out of western lands before new states were created. Southern leaders saw this as a direct threat to their political influence and to the future of the slave system.
The existing slave states
Lincoln’s position left slavery alone where it already existed. He did not claim that the federal government could simply enter a state and abolish its domestic institutions.
That made him more moderate than the abolitionists who demanded immediate emancipation. But his position did not reassure the South. Lincoln was also saying that slavery should not be allowed to expand into new territory.
The distinction was legally important, but it did not make the political consequences less serious. If slavery could not move westward, the number of free states would eventually grow faster than the number of slave states.
The western territories
The western territories represented the future of the country. Kansas, Nebraska, Utah, New Mexico, and other large areas had not yet entered the Union as independent states.
Lincoln argued that Congress had the authority to regulate those territories. Keeping slavery out of them would prevent the creation of new slave states and would eventually change the balance of power in Congress and the Electoral College.
This was why the map mattered. The territories were enormous, and the question was not only where slavery existed in 1858. The question was where it might exist twenty or thirty years later.
To many white Southerners, containment looked like a slow-motion attack on their political future. If every new state entered the Union as a free state, Southern influence would continue to decline.
More Than a Legal Argument
Lincoln’s position was also moral. In his 1858 “House Divided” speech, he argued that the country could not permanently remain divided between slavery and freedom.
He believed that preventing slavery’s expansion would place the institution on a path toward what he called its “ultimate extinction.” He was not promising immediate abolition in the existing slave states, but he was openly describing the long-term result he expected.
That language mattered. Southern leaders did not hear only Lincoln’s assurances that he would not interfere with slavery where it already existed. They also heard his prediction that slavery could not survive if it was denied new territory.
Lincoln also had to speak carefully to white voters in Illinois. He opposed slavery, but he did not campaign as an advocate of racial equality in voting, social relations, or political power. His political language focused on the injustice and economic consequences of slavery while also reflecting the racial attitudes common among many white voters of the time.
This combination made Lincoln difficult to classify. He was not an immediate abolitionist, but he was not willing to accept the permanent expansion of slavery either.
The 1860 Presidential Campaign: No Change in Position
When Lincoln moved from Illinois politics to the national stage, he did not abandon the position he had taken in the debates with Douglas.
The 1860 Republican Party platform opposed the expansion of slavery into the territories. It also condemned John Brown’s raid on Harpers Ferry and stated that the party did not intend to interfere with slavery in the states where it already existed.
Lincoln’s campaign also relied heavily on his previous public statements. He told journalist John W. Fell that, if elected, the public would find him “as I am on record—nothing less, nothing more.”
That statement captured Lincoln’s political strategy. He did not try to make himself acceptable by promising one position in the North and another in the South. His record was already public, and he allowed voters to judge him by it.
In his First Inaugural Address, delivered after several Southern states had begun seceding, Lincoln again stated that he had no lawful right to interfere with slavery in the states where it already existed. But he also defended the Union and rejected the idea that a state could simply leave whenever it disagreed with the federal government.
His position remained consistent: slavery would not be immediately destroyed where it already existed, but it would not be permitted to expand, and the Union would not be dissolved.
How Lincoln Reached the Republican Nomination
Lincoln’s consistency alone did not carry him to the White House. He also needed an effective political organization.
After losing the 1858 Senate race, Lincoln did not abandon his platform. Instead, his supporters worked to present him as a candidate who could unite Republicans from different parts of the country.
The second-choice strategy
David Davis, an influential Illinois judge and one of Lincoln’s political allies, recognized that Senator William H. Seward of New York was the leading Republican candidate but also a divisive figure within the party.
Lincoln’s supporters used a second-choice strategy. Delegates who preferred another candidate were encouraged to consider Lincoln if their first choice failed. His supporters described him as a moderate Republican who could win votes in the West and avoid some of the opposition surrounding Seward.
This did not mean Lincoln had changed his position on slavery. It meant his supporters believed the same position could be presented as both firm and politically acceptable.
The rail splitter image
In December 1859, Jesse Fell, a newspaper editor living in Illinois, encouraged Lincoln to prepare an autobiographical sketch for distribution to newspapers. The sketch emphasized Lincoln’s humble frontier background.
Richard Oglesby and other supporters helped develop the “Rail Splitter” image. Wooden fence rails associated with Lincoln’s youth became political symbols of the self-made western man.
The image was simple, but effective. Lincoln’s lack of Eastern wealth and social status became part of his appeal. He could be presented as an ordinary man who had risen through hard work, education, and political ability.
The press also played a major role. Charles Ray of the Chicago Tribune promoted Lincoln’s speeches, while Illinois Republicans worked to make Chicago the site of the 1860 Republican National Convention.
Why Indiana mattered
Indiana was an important part of the Republican strategy. Northern Indiana had strong anti-slavery sentiment, while southern Indiana included many settlers with cultural and family connections to the South.
Lincoln had lived in Indiana from the age of seven until he was twenty-one. His supporters used that connection to present him as a western candidate who understood frontier values.
David Davis worked with Indiana Republicans Henry S. Lane and Caleb B. Smith. Their argument was that William Seward was too controversial to win the West, while Lincoln’s constitutional position could attract conservative western voters without abandoning the Republican opposition to slavery’s expansion.
The strategy helped Lincoln build support beyond Illinois. The Republican Party needed the western states, and Lincoln’s friends argued that he was the candidate most likely to carry them.
The Chicago convention
The Republican convention opened in Chicago in May 1860. Seward arrived with strong Eastern support, but Lincoln’s organization had prepared carefully.
Lincoln supporters filled the convention hall and made his presence felt through organized cheering and public enthusiasm. Behind the scenes, Davis and other political managers worked to gather votes from delegates whose first choices could not win.
Lincoln had instructed his supporters not to make contracts that would bind him. Davis nevertheless worked to secure support, including support from Indiana. Lincoln was nominated on the third ballot.
After the election, Lincoln appointed Caleb B. Smith as Secretary of the Interior. The appointment reflected the political relationships that helped him win the nomination, although the details of the convention negotiations remain part of the larger story of nineteenth-century political deal-making.
Why the South Refused to Trust Lincoln
Lincoln promised not to abolish slavery in the states where it already existed. Even so, many Southern leaders considered his election an immediate threat.
They understood the practical consequences of containment. If slavery could not expand into the territories, the South would have difficulty maintaining its influence in the Senate. New free states would eventually outnumber slave states, and the Republican Party could govern without Southern electoral support.
Lincoln’s words about “ultimate extinction” made the threat seem even more direct. Southern leaders did not necessarily believe that Lincoln planned to free enslaved people on his first day in office. They feared that his policy would place slavery on a path from which it could not recover.
They also viewed the Republican Party as a sectional organization. It had little or no support in much of the South, and many Southern voters treated moderate Republicans, radical abolitionists, and John Brown as parts of the same danger.
That view ignored real differences within the Republican Party, but it reflected the depth of Southern fear. From the Southern perspective, Lincoln’s moderation did not make him safe. It made his policy more politically effective.
The election without Southern support
Lincoln won the 1860 election without carrying the Southern states. In several states, his name did not appear on the ballot at all.
That result demonstrated something Southern leaders found alarming: a Republican candidate could win the presidency through Northern and western votes without needing Southern electoral support.
The election therefore represented more than a change in presidents. It showed that the political balance of the country had shifted.
For Lincoln, the election created a constitutional crisis. He believed the Union was permanent and that secession was not legally valid. For many Southern leaders, the election showed that the old political system could no longer protect their interests.
Conclusion: When Political Debate Gave Way to Secession
Lincoln carried the same basic position from the 1858 debates into the 1860 presidential campaign. He opposed the expansion of slavery, accepted that slavery existed under state authority where it was already established, and defended the power of the federal government over the territories.
That consistency helped him win support in the West and avoid the appearance of a candidate who would change his position for political convenience. It also made him easier for Southern leaders to understand—and easier for them to fear.
To many white Southerners, a president who promised to contain slavery was almost as dangerous as an immediate abolitionist. They believed containment would eventually destroy the political and economic system on which their society depended.
When the election returns came in on November 6, 1860, Lincoln’s victory confirmed that the Republican Party could control the federal government without Southern votes. For the South, this looked like the loss of political power inside the Union.
The arguments had not ended, but the political system was beginning to break apart. An unyielding president-elect was preparing to defend the Union, while Southern states began preparing to leave it.
The next question was no longer only what Lincoln believed the Constitution allowed. It was how those beliefs would shape his response when secession became a reality.
