Why is lincoln's inaugural adress important

Abraham Lincoln's Inauguration 
March 4, 1861 
Monday, March 4, 1861, was a big day for Abraham Lincoln and for America. That morning, he and outgoing President James Buchanan left the Willard Hotel, which is nearby the White House, in a horse-drawn carriage bound for the Capitol. Shortly after 1 p.m., Chief Justice of the Supreme Court Roger B. Taney administered the presidential oath of office. 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.
