ألفونسو السادس ملك قشتالة
Álvar Fáñez (or Háñez) (died 1114) was a Leonese nobleman and military leader under Alfonso VI of León and Castile, becoming the nearly independent ruler of Toledo under Queen Urraca. He became the subject of legend, being transformed by the "Poema de Mio Cid", Spain's national epic, into Álvar Fáñez Minaya, a loyal vassal and commander under Rodrigo Diaz de Vivar, El Cid, during the latter's exile and his conquest of Valencia.
