Pope Benedict XIV (Latin: Benedictus XIV; Italian: Benedetto XIV; 31 March 1675 – 3 May 1758), born Prospero Lorenzo Lambertini, was head of the Catholic Church and ruler of the Papal States from 17 August 1740 to his death in 1758.Perhaps one of the best scholars to sit on the papal throne, yet often overlooked, he promoted scientific learning, the Baroque arts, reinvigoration of Thomism, and the study of the human form. Firmly committed to carrying out the decrees of the Council of Trent and authentic Catholic teaching, Benedict removed changes previously made to the Breviary, sought peacefully to reverse growing secularism in European courts, invigorated ceremonies with great pomp, and throughout his life and his reign published numerous theological and ecclesiastical treatises. In governing the Papal States, he reduced taxation on some products, but also raised taxes on others; he also encouraged agriculture and supported free trade within the Papal States. A scholar, he created the Sacred and Profane Museums, now part of the present Vatican Museum. He can be considered a polymath to an extent due to his numerous studies of ancient literature, his publishing of ecclesiastical books and documents, his interest in the study of the human body, and his devotion to art and theology.

However, towards the end of his papacy, Benedict XIV was forced to contend with issues surrounding the Society of Jesus and expelled them from Portugal in 1758 just before his death at the behest of Joseph I. Despite his skepticism at the manner in which the Portuguese considered the Jesuits, he nonetheless contributed to their expulsion.

Horace Walpole described him as "loved by papists, esteemed by Protestants, a priest without insolence or interest, a prince without favorites, a pope without nepotism, an author without vanity, a man whom neither intellect nor power could corrupt."
