The European family crest, particularly, the origin of Shield of Arms has been identified in the early 12th century in England. In the 11th and 12th century, common tactic of battle was grouped cavalry charge with lance and shield into enemy once and if it did not break enemies away, then knights went into combat with hand to hand. Because of massive hand combats, often it was necessary to identify combatants with clear symbol mark. Some other argument is that such emblem was used before William the Conquer in the northwestern Europe and it was brought with the conquer into England.
