In 1406, upon the death of his elder brother, King Henry III of Castile, Ferdinand declined the Castilian crown and instead, with Henry's widow Catherine of Lancaster, became coregent during the minority of his nephew John II of Castile.[3] In this capacity he distinguished himself by his prudent administration of domestic affairs.
He is buried in the Crown of Aragon's royal pantheon of the monastery of Poblet, in a magnificent tomb ordered by his son Alfonso to Pere Oller in 1417.
The Italian humanist Lorenzo Valla wrote an official biography of Ferdinand, Historiarum Ferdinandi regis Aragonum libri sex.

Appearance and character
"He was tall, a little more than average, and thin and ruddy, and his cheeks had a few freckles... very patient to all who wanted to talk to him, even if their speeches were ordinary or not well-reasoned..."[7]
