Stephen Douglass (1813-1861) became the leader of the Democratic Party and contended for the Senate in the state of Illinois in 1858. His rival was Abraham Lincoln, and both embarked on a series of debates on the issue of slavery that are renowned as one of the most important debates in American politics. Before the Civil War, he supported the idea of popular sovereignty concerning the issue of slavery.
