About Stephen IV
Pope Stephen IV
Pope Stephen IV (died January 24, 817) served as bishop of Rome and ruler of the Papal States from June 816 until his death. His pontificate, though brief, was marked by significant diplomatic and ceremonial events that underscored the close relationship between the papacy and the Carolingian Empire.
Life and Historical Context
Stephen IV hailed from a noble Roman family, the same lineage that would later produce Popes Sergius II and Adrian II. He received his early education and ecclesiastical training at the Lateran Palace and was ordained a subdeacon and then a deacon by Pope Leo III. His election as pope followed swiftly after Leo III's death, occurring within ten days, on or about June 22, 816. This rapid succession may have been an effort by the Roman clergy to preempt interference from the Carolingian emperor, Louis the Pious.
Pontificate and Major Actions
Immediately upon his consecration, Stephen IV required the Roman populace to swear fealty to Emperor Louis the Pious. He then dispatched envoys to the emperor to announce his election and arrange a meeting. In August 816, Stephen departed Rome for the emperor's convenience, accompanied by King Bernard of Italy, Louis's nephew.
In early October 816, at Reims, Stephen IV performed a pivotal act by anointing Louis the Pious as emperor and placing a crown upon his head. At the same ceremony, he crowned Louis's wife, Ermengarde of Hesbaye, as augusta. This event is viewed as an attempt by the papacy to reassert its role in the creation of emperors, a role that had been somewhat diminished by Louis's previous self-coronation. During his time with Louis, Stephen received gifts, including land for the Roman Church, and the pact between the popes and the Franks was renewed, confirming the privileges of the Roman Church and the existence of the Papal States.
Stephen IV also intervened to secure the release of Roman political prisoners held by Louis, who had been exiled due to conflicts during Pope Leo III's reign. He is also believed to have advocated for reforms among the clergy, including the separation of men and women in convents and regulations on their consumption of food and wine.
Later Life and Death
After visiting Ravenna on his return journey, Stephen IV arrived back in Rome before the end of November 816. He reportedly altered Pope Leo III's policies, moving away from favoring clergy over the lay aristocracy. After conducting traditional ordinations in December and confirming the possessions of Farfa Abbey, Stephen died on January 24, 817. He was buried in St. Peter's Basilica and was succeeded by Pope Paschal I.
