Politics of the United States during World War II President Franklin Delano Roosevelt and Vice President Henry A. Wallace won the election of 1940, and were at the helm of the nation as it prepared for and entered World War II. Roosevelt sought and won an unprecedented fourth term in office in 1944, but this time with Harry S. Truman as his Vice President. Roosevelt, who had been a victim of Polio early in life, died in April 1945, and Truman assumed the Presidency through the end of the war.
Causes of World War II Among the causes of World War II were Italian fascism in the 1920s, Japanese militarism and invasion of China in the 1930s, and especially the political takeover in 1933 of Germany by Adolf Hitler and his Nazi Party and its aggressive foreign policy. The immediate cause was Britain and France declaring war on Germany after it invaded Poland in September 1939.
