Pope Alexander VIII served as the head of the Catholic Church and ruler of the Papal States from October 1689 until his death in February 1691. Known for reversing the policies of his predecessor, Innocent XI, he engaged in nepotism to benefit his family, leading to financial strain on the papal treasury. Despite a relatively uneventful papacy, Alexander VIII condemned certain doctrines and saw the return of Avignon to the Holy See during his reign. He is remembered for these actions during his brief time as pope.

Pope John VIII was the bishop of Rome and ruler of the Papal States, known for his efforts to counter Muslim advances in southern Italy. He sought support from the Franks and Byzantines but ultimately fortified Rome's defenses. He backed Methodius in his Slavic mission, defended him against rivals, and authorized the Bible's translation into Slavonic. John also recognized the Duchy of Croatia and resolved the Photian schism. His assassination marked the end of his pontificate, weakening the papacy thereafter.

Frances of Rome was an Italian Catholic mystic known for her devotion to charitable work and the organization of services for the less fortunate. As a Benedictine oblate, she founded a religious community of oblates who lived a shared life without taking religious vows. Frances dedicated her professional life to serving others, demonstrating a strong commitment to helping those in need and promoting spiritual growth. Her contributions to charitable services and her role as a religious leader were recognized with her canonization in 1608.

Saint Cecilia was a Roman virgin martyr venerated in various Christian denominations. She is revered as the patroness of music and musicians, with musical compositions dedicated to her. She is remembered for singing to the Lord during her wedding, symbolizing her deep faith. Her feast day on 22 November is celebrated with concerts and musical festivals. The church of Santa Cecilia in Trastevere is believed to be built on the site of her house, where she lived and died, further honoring her legacy.

Pope Stephen IX started his ecclesiastical career as a canon in Liège and was invited to Rome by Pope Leo IX, who appointed him chancellor. He was part of a delegation to Constantinople in 1054, which ultimately led to the East–West Schism. Stephen continued as chancellor to the next pope, Victor II, and was elected abbot of the Benedictine monastery of Montecassino. Elected as pope in 1057, he enforced the Gregorian Reform and continued efforts to expel Normans from southern Italy before his death in Florence.

Pope Clement XII served as the head of the Catholic Church and ruler of the Papal States from 1730 until his death in 1740.

He also acquired Cardinal Alessandro Albani's collection of antiquities for the papal gallery. In 1738, he issued a bull that publicly condemned Freemasonry for the first time in papal history.
