Kingdom of Aragon
Not to be confused with the Crown of Aragon, a group of territories over which the King of Aragon was sovereign. At first it consisted of the Kingdom of Aragon itself plus the possessions of the Count of Barcelona, and later the Kingdom of Mallorca, the Kingdom of Valencia, and several territories in the Mediterranean were added by conquest. Although it was never considered a kingdom, Catalonia was one of the territories that made up the Crown, and since it had a large population and military weight, it was considered one of the "kingdoms" of the Crown of Aragon.
