About Alexander III
Pope Alexander III
Pope Alexander III, born Roland of Siena, served as the head of the Catholic Church and ruler of the Papal States from September 7, 1159, until his death on August 30, 1181. His pontificate was one of the longest in the medieval period, spanning nearly twenty-two years.
Life and Historical Context
Born around 1100/1105, Roland's early life and education are not definitively known, though he is thought to have studied in Bologna. He rose through the ranks of the Church, becoming Cardinal-Deacon and later Cardinal-Priest, and served as papal chancellor. His election as pope in 1159 was contested, leading to a prolonged schism with antipopes supported by Holy Roman Emperor Frederick I Barbarossa. This conflict forced Alexander III to spend much of his papacy outside of Rome, residing in various strongholds and cities.
Major Contributions and Actions
Alexander III's papacy was marked by significant efforts to assert papal authority and reform the Church. He rejected an offer from Byzantine Emperor Manuel I Komnenos to end the East-West Schism, fearing Byzantine domination. A key achievement was the sanctioning of the Northern Crusades, which legitimized the use of forced conversion against pagans in Northern Europe. He convened the Third Council of the Lateran in 1179, one of the most important medieval church councils, which enacted crucial reforms, including the requirement for a two-thirds majority of cardinals to elect a pope. Alexander III also humbled King Henry II of England for the murder of Thomas Becket, to whom he was close, and later canonized Becket. He also recognized the right of Count Afonso Henriques to be king of Portugal through the papal bull Manifestis Probatum.
Legacy
Alexander III's resilience in navigating the papal schism and his diplomatic maneuvering against Emperor Frederick Barbarossa solidified the papacy's position in the complex political landscape of medieval Europe. The reforms instituted during his pontificate, particularly those from the Third Council of the Lateran, had a lasting impact on Church governance and the process of papal elections. The city of Alessandria in Piedmont is named in his honor, a testament to his influence.
