As a result, Carolingian foreign policy demanded very large, highly mobile armies that could move long distances at pace. To serve this need, Charlemagne demanded all significant landowners make themselves or a representative available for his army. He also developed corps of horsemen who could ride both to and into battle. In 792–93 Charlemagne issued a law ordering all cavalrymen to carry a spear to be thrust and stabbed toward the enemy, rather than thrown, javelin style.
