Harry S. Truman

President Harry S. Truman served as president from 1945 to 1953, succeeding on the death of President Franklin D. Roosevelt while he was still in office. The Marshall Plan was initiated to help restore the economies of Western Europe, and the Truman Doctrine and NATO were developed to curb Soviet expansion. Though he advocated several liberal domestic reforms, the Conservative Coalition controlled Congress and was not interested in adopting many of them.
