Chainmaille facts.
Did you Know that Chainmaille armor was the first metal armor used for warfare?
It is believed that the Celts invented chainmaille armor, but the Romans soon adopted it after realizing its tactical advantages. Chainmaille was made out of several different kinds of metal including brass, iron and probably the most used of all was steel. It was not until the 14th century that chainmaille slowly started to get replaced by plate armor, but it was still used as under armor for many, many years. As far as we can figure out the final demise of chainmaille in military use came about with the invention of the musket and other black powder weapons.
