Rather than accept existing chronicles—written by rivals or later scribes—Alfonso commissioned a radical reimagining of his reign.

His elevated, somewhat mythologized portrayal of Castile’s origins, royal legitimacy, and cultural superiority distorted objective historical perspective, embedding selective narratives into official memory.
