In 1488, the duke died and his grandson, Álvaro de Zúñiga y Pérez de Guzmán, succeeded him. The nobility took advantage of this situation and rebelled against the House of Zúñiga, trying to recover the power that they had over Plasencia before it was gifted away. The Catholic Monarchs, Ferdinand and Isabella, stood by them and made the revolt a success. Ferdinand swore to defend and protect the freedom and charters of Plasencia until his death.
