Who Was President During World War II?

When World War II broke out, Franklin Roosevelt was serving as president, and he continued to serve in that capacity until his death in April of 1945; at that point, Harry Truman became president. Truman served as president for close to the whole of the war’s last five months.

In 1936, Roosevelt was elected to serve as president for the first time in his career. The United States entered World Conflict II in 1941, one year after Pearl Harbor was attacked, which started the war. World War II began in 1939. At this point in time, President Roosevelt was already serving his second term as head of the United States. He was a formidable leader among the Allied Forces due to his position as Commander-in-Chief of the United States military at the time. After Harry S. Truman assumed office as president, the war did not go on for very long; yet, he was the one who gave the order to drop bombs on Japan in the summer of 1945, and he also had to deal with all of the political considerations involving the conclusion of the war.
