Used from 1400 until 1590, the Fleur de Lis flag, or French royal flag, was blue with three gold fleurs-de-lis representing the shield in the royal French coat of arms. Fleur-de-lis translates to "Flower of the Lily". From 1590-1790 the white Fluer De Lis flag with 3 emblems was one of four that was used on warships and fortresses. The simpler designs such as this were used in ordinary circumstances.
