Career

Pope Sixtus IV started his career with the church as a Roman procurator before he was appointed the vicar general of the Friars Minor in the Franciscan Order in 1464.

On September 18, 1467, Paul II made Francesco della Rovere the cardinal, and he continued to be the cardinal-priest of Vincoli’s San Pietro until 1471. During this time, he published three treatises, namely ‘De futuris contingentibus’, ‘De sanguine Christi’, and ‘De potentia dei’.

In 1471, the conclave that had gathered after the death of Paul II chose him to ascend the chair, making him the 212th Pope at St. Peter’s Basilica. He was consecrated by Guillaume d’Estouteville on August 25, 1471.

After becoming the pope, he pursued the Turkish crusade and appointed legates in Poland, Germany, Spain, Hungary and France in the hope of inspiring these countries. Although his strategy did not yield any results, he managed to bring 25 Turks prisoners to Rome. These prisoners were paraded and shown off as a symbol of triumph throughout the city.

He used his position of power to appoint and promote many of his relatives and thus encouraged nepotism.

Pope Sixtus IV followed into the footsteps of his predecessor Paul II and denounced the French King Louis XI who insisted on the royal approval of the papal decrees before their publication. Sixtus also took steps to facilitate a reunion of the Russian Church with Rome but failed.

Under his guidance, the streets of Rome were widened, hospitals and churches were restored, sanitary conditions improved, dilapidated houses were cleared up, and the city became habitable.

He built the Sistine Chapel and was elemental in the creation of the Vatican Archives. Grand festivals, such as Jubilee Year of 1475, were planned during his papacy. Several buildings were also commissioned, bearing the Della Rovere oak trees and acorns emblem, including a bridge built in his name.

During a Mass on the April 26, 1478, an assassination attempt was made on Lorenzo de’ Medici and Giuliano, in which the latter died and Lorenzo was severely injured.

In 1478, he was pressured by King Ferdinand of Aragon to publish the papal bull ‘Exigit Sincerae Devotionis Affectus’, which established the Spanish Inquisition in the Kingdom of Castile. The Pope was dissatisfied and quarreled over the Inquisition’s prerogatives and protocol.

From 1482 to 1484, he waged a war against Florence and encouraged an attack on Ferrara, relying on Ludovico Sforza for support. It eventually failed and forced Sixtus to give up on his dream to acquire the city for his nephew Girolamo.
