The Four Great Catalan Chronicles (Catalan: Les quatre grans Cròniques) were written between the late 13th century and the mid 14th century. The Chronicles narrate events of the lives of James I of Aragon, Bernat Desclot, Ramon Muntaner and Pere el Cerimoniós. The four chronicles were written with the same purpose: to justify the political actions of the rulers as well as passing their political knowledge onto their descendants. They are among the most complete historiographical sets of documents of medieval Europe, and are valued by historians for their detailed descriptions of the social and political aspects of Catalan feudal society.
