Thomas Woodrow Wilson was the 28th President of the United States. A leader of the Progressive Era, he served as President of Princeton University from 1902 to 1910, and then as the Governor of New Jersey from 1911 to 1913. With Theodore Roosevelt and William Howard Taft dividing the Republican Party vote, Wilson was elected President as a Democrat in 1912. He was President from 1913-1921. Narrowly re-elected in 1916, Wilson's second term centered on World War I. He based his re-election campaign around the slogan "he kept us out of the war", but U.S. neutrality was challenged in early 1917 when the German government proposed to Mexico a military alliance in a war against the U.S., and began unrestricted submarine warfare, sinking without warning every American merchant ship its submarines could find. Wilson in April 1917 asked Congress to declare war. He focused on diplomacy and financial considerations, leaving the waging of the war primarily in the hands of the Army. On the home front in 1917, he began the United States' first draft since the US civil war, raised billions in war funding through Liberty Bonds, set up the War Industries Board, promoted labor union growth, supervised agriculture and food production through the Lever Act, took over control of the railroads, enacted the first federal drug prohibition, and suppressed anti-war movements. National women's suffrage was also achieved under Wilson's presidency. Largely for his efforts to form the League, he was awarded the Nobel Peace Prize.
