Harry S. Truman was the 33rd President of the United States, serving from 1945 to 1953. He became president after Franklin D. Roosevelt's death, overseeing the end of World War II and making critical decisions such as authorizing the use of atomic bombs on Japan. Truman also helped establish the post-war international order by founding the United Nations and initiating the Marshall Plan to rebuild Europe.

Known for his straightforwardness and decisiveness, Truman's leadership significantly shaped mid-20th-century U.S. foreign and domestic policy.
