Juan de Idiáquez y Olazábal

Juan de Idiáquez y Olazábal (12 March 154012 October 1614)

Family background Born in Madrid, he was the only son of Alonso de Idiáquez y Yurramendi, who was secretary of Charles I of Spain, and Gracia de Olazábal. The conflict was settled in 1576 with the implementation of 61 civil laws and 24 criminal laws ordered by Idiáquez, Cardinal Juan Morón and Duke of Gandía Carlos de Borja. He left the position in 1578, and in November that year was appointed ambassador to Venice. Whilst holding this position, he was awarded the "encomienda de Penausende (Zamora), de la Orden." Idiáquez wrote to King Philip II, and described his meeting with O'Hely:"The Irish archbishop of Tuam says that it will be of great importance for the success of the confederacy of Irish Catholics, that Your Majesty should write very affectionately to the earl of Tyrone, whose name is O’Neill to induce him to enter into the confederacy openly. He already belongs to it secretly, and he should be assured that Your Majesty’s aid shall not fail them. The archbishop begs Your Majesty to order a letter to be written to the earl to that effect." — Idiáquez, in a note to Philip II

Personal life On 4 February 1563, Idiáquez married Mencía Manrique de Mújica in Bermeo, Biscay. The couple had only a son, Alonso, born February 1565 in San Sebastián. He became the 1st Duke of Ciudad Real and viceroy of Navarre.

In August 1565, Mencía died in childbirth, and in 1614 Juan de Idiáquez y Olazábal died in Segovia.
