A Kingdom is a political subdivision in which the ceremonial heads are the King and Queen. In the early days of the SCA, "The King's word is law" was the primary rule; however, in acknowledgment of the work done by both monarchs, the King and Queen are referred to collectively as "The Crown" and their word carries equal weight. At Crown Tournament, which is held twice a year in Caid, the winner of the Lists and his/her consort becomes Crown Prince and Crown Princess, and at Coronation, they are invested as King and Queen.
A Barony is a political subdivision in which the ceremonial heads are a Baron and/or Baroness. The Baron and Baroness are installed by the Crown after following Kingdom Law for selection. Additionally, Caid has one Palatine Barony, Western Seas, where the Baron and Baroness are selected alternately by a traditional armored combat Lists and an Arts & Sciences competition.
