Was Lincoln's Election Contested?

In a four-way contest, the Republican Party ticket of Abraham Lincoln and Hannibal Hamlin, absent from the ballot in ten slave states, won a national popular plurality, a popular majority in the North where states already had abolished slavery, and a national electoral majority comprising only Northern electoral votes.

Who challenged Lincoln's reelection?

Near the end of the American Civil War, incumbent President Abraham Lincoln of the National Union Party easily defeated the Democratic nominee, former General George B. McClellan, by a wide margin of 212–21 in the electoral college, with 55% of the popular vote.

Why did Lincoln's election upset many Southerners?

The Republican Party, which fielded its first candidate in 1856, was opposed to the expansion of slavery. Abraham Lincoln, the party's nominee in 1860, was seen as a moderate on slavery, but Southerners feared that his election would lead to its demise, and vowed to leave the Union if he was elected.
