Pope Clement XII, born Lorenzo Corsini in 1652, served as the head of the Roman Catholic Church from 1730 until his death in 1740. He was the first pope from the Corsini family and is known for his efforts to reform the church and improve its finances. His papacy was marked by a focus on the arts and architecture, including the commissioning of the famous Trevi Fountain in Rome. Clement XII also faced challenges during his reign, including conflicts with the Kingdom of Naples and issues related to the Jesuits. He issued the papal bull "In eminenti apostolatus," which prohibited the Freemasons from joining the church. His legacy includes both cultural contributions and significant ecclesiastical decisions.
