a long term cause
Lincoln's election
3 months
Lee surrendered April 9, 1865. Lincoln was assissinated April 15, 1865.
Not the immediate cause - it had been a long-running debate. The immediate cause was Lincoln's election victory on a ticket of no new slave-states.
The Election of 1864. ... of history's most beloved Presidents, was nearly defeated in his reelection attempt in 1864. Yet by that summer, Lincoln himself feared he would lose. ... Notice that citizens of the Confederacy did not vote in the election.
Lincoln's opponent in the 1864 presidential election was none other than his long time rival Stephan Douglas. Up until election day Lincoln and much of the country had assumed his failure for re-election.
Only about two years. Then he quit to run against Lincoln in the 1864 election.
Lincoln was not an abolitionist. He believed the US Constitution allowed slavery. It would be a long time before 3/4 of the states could ratify an amendment to outlaw it and some means could no doubt be worked out to end it voluntarily before that would happen.
Long lasting consequences that the election of 1860 had was that the South didn't want Abraham Lincoln to become the president so states in the South seceded from the Union. Soon, the Civil War began. The South believed that as a Republican, Lincoln would do all he could to abolish or contain slavery, despite the fact he promised to enforce the Fugitive Slave Act and to let slavery alone where it already existed.
The issues that led to the secession had been festering for a long time, but it was the election of Abraham Lincoln that precipitated the secession.
During the Lincoln-Douglas debates in 1858, Lincoln used the "House divided against itself" statement as a reference to the issue of slavery. Lincoln was saying in effect that as long as the nation was fighting over the slavery issue, it would cause great harm to itself.
The capture of Atlanta helped Lincoln's campaign for re-election. Many people in the North had been upset with the long duration of the war. Sherman, however, showed that definite progress was being made toward victory. Union voters re-elected Lincoln in a landslide.
