Pedro Alfonso de León

Pedro Alfonso de León (c. 1196 – 1226) was a Leonese Spanish noble of the House of Burgundy.

He was elected Grand Master of the Order of Santiago in 1225, succeeding Fernán Pérez Chacín in the role.

Some chroniclers hold that he was the illegitimate son of Alfonso IX of León and an unknown woman,[citation needed] while others maintain that his mother was Aldonza Martínez de Silva, daughter of Martín Gómez de Silva and his wife Urraca Ruiz de Cabrera.

[1] Still other historians have cast doubt on Pedro Alfonso's status as Alfonso IX's illegitimate son, that he existed at all or that he was a Grand Master of the Order of Santiago.

[a] The name of his wife is not known, and historians disagree over whether Pedro Alfonso had one or two children.
