Robert de Sable from Assassin's Creed

Robert de Sable (died 1191) was the eleventh Grand Master of the Knights Templar[2] from 1190 until his death, and a lieutenant in the Crusader army of King Richard I.

Born into a powerful family, Roberto was immersed in nobility from birth. He eventually became lord and ruler of the Sarthe region in Anjou, France. Robert subsequently entered the order of the Knights Templar and reigned as its Grand Master in 1191.

During the Third Crusade, Robert and the Knights Templar, along with the rest of the Crusader army, besieged the city of Acre, which soon fell. Throughout August 1191, they also recaptured many fortresses and cities along the Palestinian coast, which had previously been lost.
