The German rulers were forceful and powerful men, and, surrounded by potential enemies, circumstances dictated the necessity of rule by strength based on military capacity. In the later 15th century, three houses rose above the others; the families of Wittelsbach, Luxemburg and the powerful Austrian Hapsburgs. The struggles of these and other houses, and of the knights and towns, were to be a feature of German history throughout the Middle Ages. This title details the dress, weapons, heraldry and insignia of these prolific forces.
