Antipope Anacletus II

Antipope Anacletus II. He was a figure of immense controversy during the Investiture Controversy, whose contested election in 1130 triggered a major schism within the Catholic Church. Born Pietro Pierleoni, his claim to the papacy was vigorously opposed by Pope Innocent II, leading to a bitter eight-year conflict that divided Europe. His reign, though ultimately deemed illegitimate, significantly influenced the political and religious landscape of the 12th century.

Early life and background

Pietro Pierleoni was born around 1090 into the powerful and wealthy Pierleoni family, a clan of Roman nobles of Jewish origin who had converted to Christianity. He received an excellent education, initially studying in Paris under renowned scholars like Peter Abelard, before entering the religious life as a Benedictine monk at the prestigious Abbey of Cluny. His family's immense influence and wealth within Rome facilitated his rapid rise through the ecclesiastical ranks, leading to his appointment as Cardinal Deacon of Santi Cosma e Damiano by Pope Paschal II. He later served as a papal legate in England and France, building a network of connections across Europe before the death of Pope Honorius II created a vacancy on the Chair of Saint Peter.

Election and papal claim

Following the death of Pope Honorius II in 1130, the College of Cardinals fractured into two factions. A majority, heavily influenced by the Pierleoni family and their allies like the Frangipani family, swiftly elected Pietro Pierleoni as pope, and he took the name Anacletus II. This election occurred in the fortified Church of San Marco. However, a smaller but influential group of cardinals, including Cardinal Haimeric, contested the procedure as irregular and, fearing the dominance of Roman families, elected Gregorio Papareschi as Pope Innocent II in a clandestine ceremony at the Church of Santa Maria in Trastevere. This dual election immediately plunged the Papal States into a state of schism, with both claimants appealing for recognition from the secular rulers of Christendom.

Conflict with Innocent II

The schism became a protracted political and military struggle for control of Rome and the papacy. Anacletus II, with the steadfast support of the Roman commune and his family's militia, secured firm control of Rome itself, forcing Pope Innocent II to flee north. Innocent II sought refuge in France, where he convened the Council of Étampes to plead his case. The conflict drew in major European powers; Anacletus II secured a crucial alliance with Roger II of Sicily, whom he crowned King of Sicily in 1130 in exchange for military support. Conversely, Innocent II gained the decisive backing of Bernard of Clairvaux, whose powerful preaching and diplomacy won over key figures like Holy Roman Emperor Lothair III, King Louis VI of France, and Henry I of England.

Support and opposition

The division of support largely followed political and reformist lines. Anacletus II commanded loyalty within central Italy, holding Rome, the Duchy of Apulia, and the allegiance of the Normans under Roger II. His power base was the Roman aristocracy and those opposed to Imperial interference. The opposition, marshaled by Bernard of Clairvaux, was formidable. Bernard denounced Anacletus II as a "Jewish usurper" in virulent letters and at major councils like the Council of Pisa, framing the conflict as a battle for the soul of the Gregorian Reform. This campaign successfully isolated Anacletus II diplomatically, ensuring that most of France, Germany, and England recognized Innocent II as the legitimate pontiff.

Death and legacy

Anacletus II died in Rome on 25 January 1138, still in possession of the city but increasingly isolated. His death effectively ended the schism, as his remaining supporters, including his appointed successor Victor IV, quickly submitted to Pope Innocent II following the Second Lateran Council. Although his papacy was later formally condemned, his reign had lasting consequences. The schism weakened the independence of the Papal States and demonstrated the growing political power of reforming clerics like Bernard of Clairvaux. Furthermore, his coronation of Roger II of Sicily solidified Norman rule in southern Italy, altering the balance of power in the Mediterranean for centuries.
