1) Hitler's invasion of Poland in September 1939 drove Great Britain and France to declare war on Germany, marking the beginning of World War II. Over the next six years, the conflict would take more lives and destroy more land and property around the globe than any previous war.

2) In 1937, Japan invaded China, starting what would become known as the Second Sino-Japanese War. After the Japanese attack on Pearl Harbor, the war would merge into the greater conflict of World War II as a major front of what is broadly known as the Pacific War.
