The relationship between Maria and Alfonso was unhappy: from 1327 before their marriage, Alfonso had a relationship with Leonor Nunez de Guzman. In 1335, Maria returned to her father in Evora, who demanded that Alfonso separated from Leonor by use of alliances with the Pope, the Muslims and rebels inside Castile, and finally by an invasion. In the peace treaty of Sevilla in July 1340, Alfonso agreed to have Leonor imprisoned in a convent.
At the death of Alfonso 26 march 1350, Maria secured a power position by exerting influence upon the leader of her son's council, Juan Alfonso de Alburquerque. She participated in the rebellion against her son in 1354, and turned over Toro to the rebels, which caused his imprisonment. After this, she returned to Portugal.
She died in Evora on 18 January 1357 and is buried in the Chapel of the Kings in Seville Cathedral.
