Saint George's Cross
In heraldry, Saint George's Cross (also known as the Cross of Saint George) is a red cross on a white background, which, from the Late Middle Ages, has been associated with Saint George, a military saint who is often depicted as a crusader. Associated with the Crusades, the red-on-white cross has its origins in the 10th century and was subsequently used as the ensign of the Republic of Genoa.
