The Known World of the Current Middle Ages encompasses the United States, Canada, Australia, New Zealand, Iceland, England, Germany, Italy, Sweden and Japan. It is divided into fifteen kingdoms, each ruled by a king and queen who have won the Crown in a medieval tournament. The Kingdoms may be subdivided into Principalities ruled by a Prince and Princess who also owe their coronets to victory in combat. Kingdoms and Principalities are composed of local branches called provinces, baronies, cantons, shires and similar names from other languages. There are over 500 local branches in the Known World.
