Knights Templar Flag

 The Flag of the Knights Templars, also known as the Crusader Flag, is a red cross on a background divided by a black and a white band. The cross comes from Saint George's Cross, also called Cross of Saint George, a red cross on a white background, which from the from the Late Middle Ages became associated with Saint George, the military saint, often depicted as a crusader. The red cross was a symbol of martyrdom, and to die in combat was considered a great honour that assured a place in heaven.

The Design of the Knights Templars Flag comes from Beauceant Flag.  The Beauceant was the Battle Flag of the Templars. The Beauceant Flag consisted of a vertical rectangle composed of two bands, one white and one black. At the top was the red cross. Black and white represent the duality of darkness and light: Christian Warriors were fair and favorable to the friends of Christ, but they were dark and terrible to his enemies.
