2In June 1858, the Illinois Republican Convention nominated Abraham Lincoln to challenge Stephen A. Douglas for the U.S. Senate. Lincoln wrote Douglas on July 24, 1858, inviting him to participate in a series of debates. With this invitation, Lincoln set the stage for what would become one of the most famous local political contests in U.S. history and a precursor to the 1860 presidential election. Prior to the seven debates between Lincoln and Douglas, Lincoln had already made sixty-three speeches in 1858, and Douglas claimed to have made one-hundred and thirty. Douglas, the incumbent, was more widely known than Lincoln and had the numeric advantage of the Democrats in the General Assembly, which selected U.S. senators in those days. He also represented a divided party and faced a growing population in northern Illinois that was hostile to slavery. Lincoln, on the other hand, had the advantage of a united Republican party, a growing antipathy toward slavery in the state, and a reputation for integrity. Nevertheless, his views on racial issues were unpopular, as was his stand on the Mexican War. The debates would highlight the fundamental differences in the men’s characters and focus on the main issues of the day, the expansion of slavery and racial equality. While the immediate effect of the debates was the re-election of Douglas, the long-term results were the opposite. Lincoln was catapulted to national prominence, allowing him to run for president in 1860, and Douglas’s campaign against Lincoln diminished his chances of future success. See 1860 Republican National Convention
Douglas replied to Lincoln’s invitation on the same day, July 24, agreeing to the debates as long as they were held at times and locations chosen by Douglas. He supplied Lincoln with that information on July 30. See 1858 Federal Election; Lincoln-Douglas Debates.

3The debates followed a format of one candidate speaking for an hour, followed by a one and a half hour response by the other candidate, and finally a half hour rebuttal by the first speaker. Douglas and Lincoln would alternate who spoke first, with Douglas speaking first at the odd numbered debates and Lincoln at the even. Douglas planned to lead off the first of seven debates, thus giving himself the advantage. Lincoln concluded the second, fourth, and sixth debates, while Douglas concluded the first, third, fifth, and seventh debates.
