Guam [SEP] World War II
During World War II, Guam was attacked and invaded by Japan on Monday, December 8, 1941, shortly after the attack on Pearl Harbor. In addition, Japan made major military moves into Southeast Asia and the East Indies islands of the South Pacific Ocean against the British and Dutch colonies, opening a new wider Pacific phase in the Second World War. The Japanese renamed Guam (Great Shrine Island). The Northern Mariana Islands had become a League of Nations mandate assigned to Japan in 1919, pursuant to the Treaty of Versailles of 1919. Chamorros indigenous island people from the Northern Marianas were brought to Guam to serve as interpreters and in other capacities for the occupying Japanese force.
