Foot Knights (1150-1320)AD MORTEM INIMICUS! "Death to the Enemy!" Sons of noble birth, the knights of 12th and 13th century Europe were the kings of the battlefield. Heavily armed and armored, few could stand in their way. Vassal to a lord, each was paid for their service through land and other riches handed down to them by their liege via the feudal system. Each knight practiced constantly to become a master of arms and horses while holding elite ranks in medieval society.
