He graduated from the Universidad Complutense, in the Colegio Mayor de San Ildefonso, with a degree in Theology. He owed his rise through the church hierarchy to Francisco Gómez de Sandoval y Rojas, a favourite in the court of Philip III. He was made a cardinal in August 1611 by Pope Paul V, as cardinal priest of Santa Susanna, and stayed in Rome to exercise his office. He was indignant when the minor nobleman Cardinal Gabriel Trejo Paniagua was chosen as Spain's crown-cardinal instead of him and, when Trejo lost political influence after his patron's fall, Borja played an even greater part in the Roman Curia. He supported the crown-cardinal Antonio Zapata y Cisneros, served a first term as Spain's ambassador to the Holy See (1616–19), participated in the Holy Office, attended the papal conclaves in 1621 and 1623, and held the posts of Camerlengo (1627–28) and Bishop of Albano[4] (1630–1645).
His tomb at the Toledo Cathedral
From 1631 to 1634, he was once again Spain's ambassador to the Holy See and, on orders from the Spanish king, accused Pope Urban VIII (then maintaining neutrality or favouring France) in the consistory of 8 March 1632 of failing to defend Catholicism in its Thirty Years War with the Protestant nations and threatened that Spain would depose him. Part of the grounds for Spain's complaint lay in unfounded rumours of the pope siding with the Protestant Gustavus Adolphus of Sweden (a heretic in the church's eyes). In response, the pope changed his policy somewhat and made a contribution to the Spanish exchequer, which was then running out of money to finance the war. However, Borja's approach to the pope had lacked diplomacy and in retaliation Urban forced him out of Rome in 1634 and had Spain dismiss him as their ambassador.
Borja then returned to the Archdiocese of Seville, of which he was already archbishop. The patent enmity between Urban VIII and Cardinal Borja showed itself when Urban refused Philip IV's proposal of Borja for Archbishop of Toledo in 1643, though he received the post from Urban's successor Pope Innocent X in 1645, shortly before Borja's death in Toledo later that year.
In the 1632 series of alternate historyscience fiction novels, the South European thread is a series of novels in which Borja is the villain. He attempts to depose and kill Urban VIII, who is perceived by Spain as sympathetic to Gustavus Adolphus and his heretical American allies in the United States of Europe. Borja, exceeding his orders from Madrid, has a rump consistory declare him Pope; but is widely dismissed as an anti-pope.
