Chain mail, sometimes called chainmail, maille, or chain maille, is a type of functional armor. The wearing of chain mail has always been an effective means of protection in combat and war for centuries. Its use dates back to the Greek and early Roman empire where warriors and legionnaires donned metal plate and mail armor. Chain mail armor was the first type of medieval armor developed. The medieval era knights are remembered for their elaborate armor and battle shields in brilliant colors. The quality of the chain mail was important to know the battle efficiency and made a fashion statement too reflecting the status and lifestyle of the knights. Well-made chain mail was a prized possession of fighting knights.

The evolution of chain mail was a direct response to improvement in weaponry. In the mid 1500's, there was an evolution of plate armor to entire suits of highly crafted works of art in metal. Prior to this time, chain mail was the most prevalent and effective type of body armament. Chain mails weighed about the same as full body plate style. The average weight was about 45 - 55 pounds. It was always worn with padding and protective clothing to further protect and insulate from the heat and cold. Today its use is confined to as a captivating display piece in the homes.
