Although Eleanor and her sons reached an agreement with Peter to live peacefully in his court, the situation remained unstable. Henry and his brothers Fadrique, Tello and Sancho staged numerous rebellions against the new king. Also, to strengthen his position and gain allies, Henry married Juana Manuel, the daughter of Juan Manuel, Prince of Villena, adelantado mayor of Murcia and Lord of Villena, the most prosperous nobleman of the realm. In 1351, the King took counsel from Juan Alfonso de Alburquerque, María of Portugal's right-hand man. He became convinced that his father's lover was the instigator of the uprisings, so he ordered Eleanor to be incarcerated and finally executed in Talavera de la Reina.
