Answer;
-To assure the Southern states that they would make their own decisions about slavery.
Step-by-step explanation;
-With the swearing of his official vows, Lincoln became the 16th president of the United States. His speech was a very important one because he would be speaking not only as the new president but also as the leader of a nation in crisis. Lincoln was well prepared. He had sought lots of help to deliver the right message in his inaugural address.
-Lincoln's inaugural address was stirring. He appealed for the preservation of the Union. To retain his support in the North without further alienating the South, he called for compromise. He promised he would not initiate force to maintain the Union or interfere with slavery in the states in which it already existed.
