Overview

Pope Alexander II guided the Church through one of the most decisive periods of reform in medieval history. Elected according to the new procedures established by Pope Nicholas II in In Nomine Domini, his election was immediately challenged by an imperial faction that supported Antipope Honorius II.

Despite years of conflict, Alexander defended the reformed election and continued the movement associated with St. Leo IX and his successors. A central collaborator was Archdeacon Hildebrand, the future Pope St. Gregory VII.

Together they strengthened ecclesiastical discipline and prepared the Church for one of the greatest reforming pontificates in history.

Early Life

Alexander II was born around AD 1010 as Anselm of Baggio near Milan. His work within the eleventh-century reform movement is better documented than an itemized curriculum.

He became widely respected for personal holiness, wisdom, humility, firm leadership.

Bishop of Lucca

Before becoming pope, Anselm served as Bishop of Lucca. He became known as an energetic reformer who promoted worthy clergy, faithful liturgy, care for the poor, ecclesiastical discipline.

His work attracted the attention of the reforming popes in Rome.

Becoming Pope

Following the death of Pope Nicholas II the reforming cardinals elected Anselm of Baggio as pope.

He accepted the name Alexander II and was consecrated on September 30, AD 1061. His election followed the procedures established in In Nomine Domini which emphasized the principal role of the College of Cardinals in choosing the pope.

Opposition from Antipope Honorius II

Not everyone accepted Alexander’s election.

An imperial faction led by several German and Italian bishops elected Cadalus of Parma who became Antipope Honorius II A lengthy struggle followed.

After several years of dispute, the Synod of Mantua in AD 1064 recognized Alexander II as the legitimate pope, bringing the schism largely to an end.

Continuing the Gregorian Reform

Alexander vigorously continued the reform movement.

He opposed simony, clerical marriage, corruption in episcopal appointments, political interference in Church affairs.

He promoted clerical celibacy, episcopal accountability, monastic renewal, faithful observance of canon law.

Many of these reforms were directed by Hildebrand whose influence within the Roman Curia continued to grow.

Relations with England

Alexander maintained close relations with William, Duke of Normandy. Before the Norman Conquest of England in AD 1066 Alexander sent William a: Papal Banner as a sign of papal favor for William’s claim, though this did not constitute a blanket approval of every military action that followed.

After the conquest, Alexander encouraged the reform of the English Church and supported the work of St. Lanfranc Archbishop of Canterbury.

Missionary Activity

Alexander supported missionary work among: the peoples of Northern Europe, the Slavs, newly converted kingdoms.

He encouraged bishops to strengthen Christian education and the proper celebration of the sacraments.

Hildebrand

Perhaps Alexander’s greatest contribution was his confidence in Hildebrand. He entrusted him with papal diplomacy, Church administration, reform councils, relations with secular rulers.

When Alexander died, Hildebrand was immediately chosen as Pope St. Gregory VII whose pontificate fulfilled many of the reforms begun under Alexander.

Death

Alexander died on April 21, AD 1073 in Rome. His death was deeply mourned throughout the reform movement.

Only one day later, the clergy and faithful acclaimed: Hildebrand as Pope St. Gregory VII.

The Pope Who Prepared St. Gregory VII

When Anselm of Baggio became Pope Alexander II in AD 1061, the Church faced opposition to the newly reformed papal election process and ongoing struggles against simony and political interference. Throughout his twelve-year pontificate, Alexander steadfastly defended the freedom of the Church while relying on the wisdom and administrative skill of Hildebrand. By the time Alexander died in AD 1073, Hildebrand had become the acknowledged leader of the reform movement and was immediately acclaimed as Pope St. Gregory VII. In this way, Alexander II served as the essential bridge between the foundational reforms of Nicholas II and the dramatic renewal that would soon reshape the medieval Church.
