Armour is protective plates or clothing meant to shield a human from intentionally inflicted harm. Armour has been in use for all recorded history, beginning with hides, leather, bone, progressing to bronze, steel, ballistic cloth, ceramics, and depleted uranium. Armour has been primarily a way to protect oneself from harm in combat and military engagements.
In European history, common armour types were the lorica segmentata, the chainmail hauberk, the gambeson and later the full steel plate armour used by late medieval knights. In feudal Japan, laquered lamellar armours were popular.
