Following are ten key facts that are important to understanding the life and presidency of the 33rd president of the United States. 01 of 10 Grew Up on a Farm in Missouri Public Domain/Wikimedia Commons Truman's family settled on a farm in Independence, Missouri.

Public Domain/Wikimedia Commons Truman never did get a law degree but instead decided to open a men's clothing store which was not a success. He moved into politics through administrative positions. He became the US Senator from Missouri in 1935. He led a committee called the Truman Committee whose job was to look into military wastefulness. 05 of 10 Succeeded to the Presidency Upon FDR's Death Public Domain/Wikimedia Commons Truman had been selected to be Franklin D. Roosevelt's running mate in 1945. When FDR died on April 12, 1945, Truman was shocked to find out he was the new president. He had to step in and lead the country through the final months of World War II. 06 of 10 Hiroshima and Nagasaki Public Domain/Wikimedia Commons Truman learned after taking office about the Manhattan Project and the development of the atomic bomb. Even though the war in Europe had ended, America was still at war with Japan who would not agree to an unconditional surrender. A military invasion of Japan would have cost many thousands of lives. Truman used this fact along with a desire to show the Soviet Union the might of the US military to justify his using the bombs on Japan. Two sites were chosen and on August 6, 1945, a bomb was dropped on Hiroshima. Three days later one fell on Nagasaki. Over 200,000 Japanese were killed. Japan formally surrendered on September 2, 1945. 07 of 10 Aftermath of World War II President Truman makes his welcoming speech to the UN General Assembly at its opening session in New York, October 23, 1946.

Finally, Truman supported the creation of the United Nations at the end of the war. 08 of 10 Dewey Beats Truman Public Domain/Wikimedia Commons Truman was fiercely opposed by Thomas Dewey in the 1948 election. The election was so close that the Chicago Tribune erroneously printed on election night the famous headline, "Dewey Beats Truman." He won with only 49 percent of the popular vote. 09 of 10 Cold War at Home and Korean War Abroad Public Domain/Wikimedia Commons The end of World War II began the era of the Cold War. Truman created the Truman Doctrine that stated that it was America's duty to "support free peoples who are resisting ... subjugation by armed minorities or outside pressures." From 1950 to 1953, the US fought in the Korean Conflict attempting to stop the communist forces from the North from invading the South. The Chinese were arming the North, but Truman did not want to start an all-out war against China. The Conflict was a stalemate until Eisenhower took office. At home, the House Un-American Activities Committee (HUAC) set up hearings of individuals who had ties to communist parties. Senator Joseph McCarthy rose to fame over these activities. 10 of 10 Attempted Assassination Diagram view of the Blair House, scene of the attempt on President Truman's life.
