Harry S. Truman (May 8, 1884 – December 26, 1972) was an American politician who served as the 33rd president of the United States from 1945 to 1953. A member of the Democratic Party, he previously served as the 34th vice president from January to April 1945 under President Franklin Roosevelt and as a United States Senator from Missouri from 1935 to January 1945. Having assumed the presidency after Roosevelt's death, Truman implemented the Marshall Plan to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of communism. He proposed numerous liberal domestic reforms, but few were enacted by the Conservative Coalition which dominated the Congress.
