American Civil War
Lincoln's election

Lincoln's election in November 1860 was the final trigger for secession. Southern leaders feared Lincoln would stop slavery's expansion and put it on a course toward extinction. However, Lincoln would not be inaugurated until March 4, 1861, which gave the South time to secede and prepare for war during the winter of 1860-61.

According to Lincoln, the American people had shown they had been successful in establishing and administering a republic, but a third challenge faced the nation: maintaining a republic based on the people's vote, in the face of an attempt to destroy it.
