was probably more complex and specific. Activity of the Inquisition Start of the Inquisition Fray Alonso de Ojeda, a Dominican friar from Seville, convinced Queen Isabella of the existence of Crypto-Judaism among Andalusian conversos during her stay in Seville between 1477 and 1478. A report, produced by Pedro González de Mendoza, Archbishop of Seville, and by the Segovian Dominican Tomás de Torquemada—of converso family himself—corroborated this assertion. Spanish monarchs Ferdinand and Isabella requested a papal bull establishing an inquisition in Spain in 1478. Pope Sixtus IV granted a bull permitting the monarchs to select and appoint two or three priests over forty years of age to act as inquisitors. In 1483, Ferdinand and Isabella established a state council to administer the inquisition with the Dominican Friar Tomás de Torquemada acting as its president, even though Sixtus IV protested the activities of the inquisition in Aragon and its treatment of the conversos. Torquemada eventually assumed the title of Inquisitor-General. Thomas F. Madden describes the world that formed medieval politics: "The Inquisition was not born out of the desire to crush diversity or oppress people; it was rather an attempt to stop unjust executions. Yes, you read that correctly. Heresy was a crime against the state. Roman law in the Code of Justinian made it a capital offence. Rulers, whose authority was believed to come from God, had no patience for heretics". Ferdinand II of Aragon pressured Pope Sixtus IV to agree to an Inquisition controlled by the monarchy by threatening to withdraw military support at a time when the Turks were a threat to Rome. The pope issued a bull to stop the Inquisition but was pressured into withdrawing it. On 1 November 1478, Sixtus published the Papal bull, Exigit Sinceras Devotionis Affectus, through which he gave the monarchs exclusive authority to name the inquisitors in their kingdoms. The first two inquisitors, Miguel de Morillo and Juan de San Martín, were not named until two years later, on 27 September 1480 in Medina del Campo. The first auto-da-fé was held in Seville on 6 February 1481: six people were burned alive. From there, the Inquisition grew rapidly in the Kingdom of Castile. By 1492, tribunals existed in eight Castilian cities: Ávila, Córdoba, Jaén, Medina del Campo, Segovia, Sigüenza, Toledo, and Valladolid. Sixtus IV promulgated a new bull categorically prohibiting the Inquisition's extension to Aragón, affirming that: According to the book A
