El Cantar de Mio Cid is the oldest-known text in Spanish literature and it narrates part of the life of Cid, an epic hero. Exiled unjustifiably by King Don Alfonso, Cid, with a group of followers, fights to regain his honour against the Moors and against anyone who is plotting against him. Cid’s disgrace turns into triumph, and his misery into power, eventually leading to the conquest of Valencia from the Muslims.
