Juan de Borja y Castro

Juan de Borja y Castro (1533, Bellpuig – 3 September 1606, El Escorial) was a Spanish noble of the House of Borja and the House of Castro. Borja was a soldier, diplomat and a worker for the Spanish state. He is best known for being the first Count of Mayalde and count consort of Ficalho (in Portugal).

Biography Family origins and early life Juan was the third son of Francisco de Borja, 4th Duke of Gandía (later a Catholic saint) and his wife, Leonor de Castro. He was born accidentally in Bellpuig as his father was assisting at the courts Monzón as the head caballerizo representing Charles I at the time.

Between 1539 and 1543, he lived with family members in Barcelona, coinciding with his father's stint as Viceroy of Catalonia. He later moved to Gandía when his father was named the duke.

Juan was educated amongst the Jesuits at the Universidad de Gandía. In 1548, he was admitted into the Order of Santiago, which was by this time under the direct control of the Spanish monarchy.

After the death of his mother in 1546, from 1550–51, he accompanied his father to Rome, where he was going to join the Jesuits. The pair returned to Oñati, from where Juan then proceeded to attend the prestigious University of Alcalá.

At the Spanish court After returning to Spain, he was named head majordomo of María de Austria, a charge he would maintain until 1603. As recognition for his services to the state, Phillip II granted him the title of Count of Mayalde. During the reign of Philip III of Spain, he developed a relationship with the Duke of Lerma, who was his nephew. He was there named Count of Ficalho and president of the Council of Portugal, and he was added to the Spanish Council of State.
