Medieval armors were essential for Medieval's Knights in Middle Ages. They were protective covering used to prevent damage from being inflicted by a sword or other weapons. Since ancient ages when there were a hand-to-hand combat, both fighters used to protect themselves using, progressively furs from animals, leather and then metal armors. Therefore, Medieval armors are a set of (usually steel-made) plates used for covering the whole Knight's body in the Early Middle Ages and at the beginning of Modern Story.
Armors used to be used in combats, tournaments and war conflicts minimizing damages.
The first evidence of use regards Egypt around 4000 bC; they were made of crocodile's fur and leather reinforced with bronze.
