Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American politician. He was the 16th President of the United States. He was president from 1861 to 1865, during the American Civil War. Just five days after most of the Confederate forces had surrendered and the war was ending, John Wilkes Booth assassinated Lincoln. Lincoln was the first president of the United States to be assassinated. Lincoln has been remembered as the "Great Emancipator" because he worked to end slavery in the United States.[1]
