Henry I, King of Castile and Toledo (born 1204)

Henry I of Castile was King of Castile. He was the son of Alfonso VIII of Castile and Eleanor of England, Queen of Castile. He was the brother of Berengueia and Mafalda of Castile.

The Crown of Castile was a medieval polity in the Iberian Peninsula that formed in 1230 as a result of the third and definitive union of the crowns and, some decades later, the parliaments of the kingdoms of Castile and León upon the accession of the then Castilian king, Ferdinand III, to the vacant Leonese throne. It continued to exist as a separate entity after the personal union in 1469 of the crowns of Castile and Aragon with the marriage of the Catholic Monarchs up to the promulgation of the Nueva Planta decrees by Philip V in 1716.
