The Pennsic War is an annual American medieval and Renaissance camping event held by the Society for Creative Anachronism (SCA), a "war" between two large regional SCA groups: the Kingdom of the East and the Middle Kingdom. It is the single largest annual SCA event, with more than 10,000 people attending each year, from as far as China, South Korea, Sweden, Germany, France, Italy, Greece, and Australia.

SCA armoured combat, or informally heavy combat, is a combat sport developed by the Society for Creative Anachronism (SCA) in which participants in protective body armour compete in mock combat, individual tournaments inspired by forms of historical combat, and tournament combat practiced in medieval Europe. Groups also compete, under supervision, in group battles which may approximate historically real combat, using SCA approved safe weapons. Combats are performed under the watch of marshals to maintain safety. It is variously considered a combat sport, contact sport, or a form of martial art.
