No he didn't
The election of Lincoln, who had refused to allow any extension of slavery.
Abraham Lincoln did not win any slave states in the 1860 presidential election. He secured the presidency primarily through victories in free states, receiving no electoral votes from the Southern slave states. His election was a significant factor in the secession of several Southern states and the onset of the Civil War.
The election of Abraham Lincoln of the newly-formed Republican Party, which had banned the creation of any new slave-states.
Lincoln's Emancipation Proclamation, effective from January 1863. It did not, of course, liberate any slaves, as Lincoln did not carry any authority in the South, but it licensed Union troops to liberate any slaves they came across in their Southern campaigns. More significantly, it made it impossible for free nations abroad to aid the Confederates without looking pro-slavery themselves.
None. Lincoln carried the more populous Northern states. Stephen A. Douglas(Northern Democrat), John Breckinridge(Southern Democrat), and John Bell(Constitutional Union) divided the Southern states. Lincoln had 180 electoral votes, Douglas had 12, Breckinridge had 72, and Bell had 39.
Because Lincoln had refused to allow any extension of slavery into the new Western states. So the South was doomed to be outvoted in Congress every time.
The election of Lincoln in November 1860, and his refusal to allow any extension of slavery.
Because the Republicans would not allow the creation of any new slave-states. So the South would always be outvoted in Congress.
Actually, Lincoln was on the ballot in Kentucky, Virginia, Maryland, Delaware, and Missouri.The Northern (free) states comprised 183 electoral votes (60.4%). The Southern (slave) states comprised just 120 electoral votes (39.6%). Lincoln won every free state except New Jersey.
Because the newly-elected Lincoln would not allow the creation of any new slave-states, so the South would always be outvoted in Congress.
The southern states feared the ascension of the Lincoln Administration to office would result in further loss of states' rights, which in turn would eventually result in the abolition of slavery. Lincoln's election as President was the last straw for many southern states, which led to their succession from the Union and the formation of the Confederate States of America.
