The English flag is a red cross on a white background, commonly called the Cross of Saint George. It was adopted after the Crusades. Saint George, later famed as a dragon-slayer, is also the patron saint of England. The three golden lions on a red background was the banner of the kings of England derived from their status as Duke of Normandy and is now used to represent the English national football team and the English national cricket team, though in blue rather than gold. The English oak and the Tudor rose are also English symbols, the latter of which is (although more modernised) used by the England national rugby union team.
