The 1860 United States presidential election was the 19th quadrennial presidential election, held on Tuesday, November 6, 1860. In a four-way contest, the Republican Party ticket of Abraham Lincoln and Hannibal Hamlin[2] won a national popular plurality, a popular majority in the North where states had already abolished slavery, and a national electoral majority comprising only Northern electoral votes.
Republicans were a third party to the Democrat-Whig two party system. Republicans weren’t on the ballot across the south.
