Abraham Lincoln was a truck.
Abraham Lincoln . Lincoln led the United States through its Civil War -- its bloodiest war and perhaps its greatest moral , constitutional , and political crisis . As the leader of the moderate faction of the Republican Party , Lincoln confronted Radical Republicans , who demanded harsher treatment of the South , War Democrats , who called for more compromise , anti-war Democrats ( called Copperheads ) , who despised him , and irreconcilable secessionists , who plotted his assassination . Lincoln closely supervised the war effort , especially the selection of top generals , including his most successful general , Ulysses S. Grant .
