The person on the five dollar bill is Abraham Lincoln, best known as the 16th President of the United States. Lincoln was at the center of the Civil War from 1861 to 1865, in which 11 states separated from the United States to form the Confederate States of America, also known as the Confederacy. While it seemed like the Union would lose the war at first, Lincoln put his faith in generals that helped the Union win the war.

Lincoln therefore is significant in American history for freeing slaves and helping the union win the Civil War.
