in 1858, and Stephen Douglas held their first of seven historic debates. On one side was Lincoln, the senate challenger who opposed slavery’s expansion. On the other side was Douglas, the sitting senator who believed that settlers should determine themselves “the moral and religious right of the slavery question.” At the debates’ end, Douglas was reelected. But it was Lincoln who transformed into a rising national star. He lost the battle—but more consequentially—would win The War.
In 1850, Douglas was crucial in helping pass the Compromise of 1850, which he believed would “restore peace and harmony” between the North and the South. But by 1854, he put that peace in peril by orchestrating the Kansas-Nebraska Act, which allowed settlers in the Louisiana Territory to vote for slavery’s legality.
The explosive response over the law prompted many pro-slavery and Southern Whigs to join the Democratic Party; while antislavery and Northern Whigs helped form the new GOP. Two years later, Lincoln joined its ranks, convinced that “If slavery is not wrong, nothing is wrong.”
The Lincoln-Douglas debates to follow also came on the heels of the infamous Dred Scott decision, considered by many as the worst ruling in history. In ’ majority opinion, the Chief Justice opined that African Americans “had no rights which the white man was bound to respect” and “might justly and lawfully be reduced to slavery for his benefit.”
It is in this context that Lincoln accepted his party’s nomination, declaring a “house divided against itself cannot stand.” Echoing the Bible, it was Lincoln’s bid “to rouse [men] to the peril of the times.” He attempted to do so during his debates with Douglas, attended by tens of thousands of spectators. Either Lincoln or Douglas would speak for an hour, followed by his opponent for 90 minutes, before concluding with a half hour rebuttal.
Though Lincoln failed to win the election, his rousing speeches put him on path to the by firmly establishing his main political objectives as opposing slavery’s expansion—and preserving the Union. He already knew, as Douglas later conceded: “There can be no neutrals in this war; only patriots and traitors.”
