The Maltese flag was adopted on September 21, 1964. The flag is a bi-color flag with red on the fly and white on the hoist. On the upper corner of the hoist is a symbol of the George Cross outlined in red. The red and white colors derived from the Knights of Malta during the Crusades. Their coat of arms was a white cross on a red field. The George Cross in the corner symbolizes the actual medal awarded to the Maltese people by King George VI of Great Britain. The medal was given to the people of Malta for their bravery and gallantry during World War II.
