What was the effects of the Lincoln debates of 1858?

The Lincoln-Douglas debates of 1858 significantly elevated Abraham Lincoln's national profile, establishing him as a key figure in the Republican Party and a leading opponent of slavery's expansion. While Stephen Douglas won the Senate seat, the debates highlighted the moral and political divisions over slavery in the United States, setting the stage for the 1860 presidential election. Their discussions also intensified public discourse on civil rights and contributed to the growing tensions that eventually led to the Civil War.
