Members put research into practice by constructing replica artifacts, practicing medieval arts and crafts, learning to fight with sword and shield, and so on. The Known World encompasses the United States, Canada, Australia, and Europe, with small chapters in many other parts of the globe. In all, there are over 600 local branches, divided into fourteen kingdoms. The SCA sponsors many different events. There are numerous seminars, demonstrations, and tournaments.
Banquets copy the medieval high feasts with authentic recipes and entertainment.
Various craft guilds hold meetings for those interested in specific arts. The Society also holds public demonstrations of fighting and other aspects of historical culture and technology by request. The most visible activity at a tournament is the fighting. However, a tournament also involves the pursuit of the gentler arts, such as music and dancing, to while away a pleasant afternoon. While Society events are colorful to observe, the deeper satisfactions come from becoming a participant.
