Facts and Events
Don Ferdinand de la Cerda (1253–1275) was the Crown Prince (infante) of Castile, eldest son of King Alfonso X of Castile and Violant of Aragon. His nickname, de la Cerda, means "of the bristle" in Spanish, a reference to being born with a full head of hair.
Ferdinand predeceased his father in 1275 at Ciudad Real from wounds received at the Battle of Écija. His sons did not inherit the throne of their grandfather, since their uncle Sancho, usurped the throne.
