Abraham Lincoln (February 12, 1809 - April 15, 1865) was an American statesman and lawyer who served as the 16th President of the United States from March 1861 until his assassination in April 1865. Lincoln led the United States through its Civil War--its bloodiest war and perhaps its greatest moral, constitutional, and political crisis. In doing so, he preserved the Union, paved the way for the abolition of slavery, strengthened the federal government, and modernized the economy. An astute politician deeply involved with power issues in each state, Lincoln reached out to the War Democrats and managed his own re-election campaign in the 1864 presidential election. Anticipating the war's conclusion, Lincoln pushed a moderate view of Reconstruction, seeking to reunite the nation speedily through a policy of generous reconciliation in the face of lingering and bitter divisiveness. On April 14, 1865, five days after the surrender of Confederate general Robert E. Lee, Lincoln was shot by Confederate sympathizer John Wilkes Booth and died the next day. Lincoln has been consistently ranked both by scholars and the public as among the greatest U.

S. presidents.
