In 1860, the country was torn by the issue of slavery, something which became more than evident by the time Election Day rolled in. Nine Southern states removed Lincoln from their ballots, and the North returned the favor, by removing the Democrats. Lincoln managed to win the elections, but the South was not too happy about it. The Southern states seceded from the Union and launched a Civil War that would end up killing more than 600,000 people.
