Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was an American statesman and academic who served as the 28th president of the United States from 1913 to 1921. A member of the Democratic Party, Wilson served as the president of Princeton University from 1902 to 1910, and as governor of New Jersey from 1911 to 1913, before winning the 1912 presidential election. As president, he oversaw the passage of progressive legislative policies unparalleled until the New Deal in 1933. He also led the United States during World War I, establishing an activist foreign policy known as “Wilsonianism.” He was one of the three key leaders at the 1919 Paris Peace Conference, where he championed a new League of Nations, but he was unable to win Senate approval for U.S. participation in the League.
