Lincoln was morally opposed to slavery and politically opposed to any expansion of it. On October 16, 1854, in his  Peoria Speech , Lincoln declared his opposition to slavery, which he repeated in his route to presidency.
Lincoln's plan was to get rid of slavery in the District of Columbia (which Congress did), and in the loyal border states of Delaware, Maryland, Kentucky and Missouri through compensated emancipation. At the beginning of the war, Lincoln prohibited his generals from freeing slaves even in captured territories.
