Rodrigo Daz de Vivar is called Mo Cid (meaning My Lord) by the Moors. His current task is to collect the tributes from the Moorish territory owed to his king, Alfonso VI of Len. Cid's enemy accuses him of taking some of these tributes and the king exiles him from Len and Castile. Before he leaves, he places his wife, Doa Ximena, and his two daughters, Doa Elvira and Doa Sol, in the Monastery of Cardea. The canto then gives accounts of raids in the Moorish territory in which Cid and his men get rich off of the spoils.
