Vem daterade Alfons XI av Kastilien?

Alfons XI av Kastilien, född 13 augusti 1311 i Salamanca, död 26 mars 1350 i Gibraltar, var en monark (kung) av Kastilien.

Leonor (Eleanor) de Guzmán y Ponce de León (1310–1351) was a Castilian noblewoman. After about 1330, she became the long-term mistress and favourite of Alfonso XI, with whom she had the illegitimate son Henry "the Fratricidal", future first monarch of the House of Trastámara. She held the lordship of Medina-Sidonia until she fell from grace in the wake of Alfonso's death in 1350. She was then executed by her enemies.
