After leaving Congress in 1849 Lincoln largely ignored politics to concentrate on his law practice. He was drawn back by the firestorm over the Kansas–Nebraska Act of 1854, which reversed a longstanding compromise and allowed territories to decide for themselves whether they would allow slavery. Lincoln was morally opposed to slavery and politically opposed to any expansion of it. At issue was extension into the western territories. On October 16, 1854, in his "Peoria Speech", Lincoln declared his opposition to slavery, which he repeated in his route to presidency. Speaking in his Kentucky accent, with a very powerful voice, he said the Kansas Act had a ""declared" indifference, but as I must think, a covert "real" zeal for the spread of slavery. I cannot but hate it. I hate it because of the monstrous injustice of slavery itself. I hate it because it deprives our republican example of its just influence in the world."
