Don Juan Manuel

The Prince and the Pen

Don Juan Manuel, grandson of Ferdinand III and nephew of Alfonso X, was one of the most powerful aristocrats of medieval Castile. Lord of Villena and extensive territories across the kingdom, he was a soldier, diplomat, royal councillor and regent, and for more than half a century stood at the centre of Castilian political life.

Today he is remembered principally as the author of El Conde Lucanor and as one of the great figures of medieval Spanish literature. His political career, however, was no less remarkable. He participated in wars against Granada, struggled for influence during the minorities of Fernando IV and Alfonso XI, negotiated repeatedly with the crowns of Aragon and Portugal, and spent much of his later life in conflict — and occasional reconciliation — with Alfonso XI.

This website presents a full chronological biography of that political career. It draws extensively on contemporary chancery documents, letters and charters, while using the royal chronicles more cautiously where their testimony is partisan or cannot be independently corroborated.
