Groups
The SCA has a number of different types of groups, some official and others not.
Official Groups
Kingdoms
The Kingdom is the largest groups within the SCA. To become a Kingdom a group must have a history of high level activity, at least 400 subscribing members and sufficient representative from all three peerages. It is ruled by a King and a Queen
Principalities
A Principality is a subgroup of a Kingdom. It must have at least 100 subscribing members. It is ruled by a Prince and Princess, and is subject to Kingdom law. A group which wishes to become a Principality but does not yet fit one or more of the criteria, may become a Crown Principality.
Baronies
A Barony is a group with at least 25 subscribing members. It is ruled by a Baron and a Baroness, and is subject to a Kingdom, as well as to a Principality if it lies within one.
Cantons
A Canton is the subgroup of a Barony with at least five subscribing members.
Shires
A Shire is a group with at least five subscribing members which reports directly to a Kingdom or Principality rather than a Barony.
Colleges
A college is a group based around an educational institution, usually a University. It must have at least five subscribing members.
Forts
A fort is a group based around a military base or ship. It must have at least five subscribing members.
Unofficial Groups
Households
A household is a group of members who join together usually for social reasons. They may have any of a wide variety of structures. Although they have no official status they may be recognised by Kingdom, Principality or Baronial awards.
Guilds
A Guild is a group drawn together by common interest in an Art or Science. They may have any of a number of structures.
