Berengar of Tours, in Latin Berengarius Turonensis, was an 11th-century French Christian theologian and archdeacon of Angers, a scholar whose leadership of the cathedral school at Chartres set an example of intellectual inquiry through the revived tools of dialectic that was soon followed at cathedral schools of Laon and Paris. He came into conflict with Church authorities over the doctrine of transubstantiation of the Eucharist.

Pope John X was the bishop of Rome and nominal ruler of the Papal States from March 914 to his death. A candidate of the counts of Tusculum, he attempted to unify Italy under the leadership of Berengar of Friuli, and was instrumental in the defeat of the Saracens at the Battle of Garigliano.

The Gregorian Reforms were a series of reforms initiated by Pope Gregory VII and the circle he formed in the papal curia, c. 1050–80, which dealt with the moral integrity and independence of the clergy. The reforms are considered to be named after Pope Gregory VII (1073–85), though he personally denied it and claimed his reforms, like his regnal name, honoured Pope Gregory I.

Guibert or Wibert of Ravenna was an Italian prelate, archbishop of Ravenna, who was elected pope in 1080 in opposition to Pope Gregory VII and took the name Clement III. Gregory was the leader of the movement in the church which opposed the traditional claim of European monarchs to control ecclesiastical appointments, and this was opposed by supporters of monarchical rights led by the Holy Roman Emperor. This led to the conflict known as the Investiture Controversy. Gregory was felt by many to have gone too far when he excommunicated the Holy Roman Emperor Henry IV and supported a rival claimant as emperor, and in 1080 the pro-imperial Synod of Brixen pronounced that Gregory was deposed and replaced as pope by Guibert.

The Diocese of Bergamo is a see of the Catholic Church in Italy, and is a suffragan of the Archdiocese of Milan. Geographically, Bergamo stood between the mainland interests of the Republic of Venice, and the territory of the Duchy of Milan. The duchy was regularly contested by the French and the Holy Roman Empire, which brought about repeated military operations. Internally, from the 12th to the 15th century, there was the usual party strife between the Guelphs, who generally supported the political and religious policies of the Papacy; and the Ghibellines, who generally supported the Emperors. As Kings of Italy, the emperors were feudal overlords of Lombardy.

The history of the papacy from 1046 to 1216 was marked by conflict between popes and the Holy Roman Emperor, most prominently the Investiture Controversy, a dispute over who— pope or emperor— could appoint bishops within the Empire. Henry IV's Walk to Canossa in 1077 to meet Pope Gregory VII (1073–85), although not dispositive within the context of the larger dispute, has become legendary. Although the emperor renounced any right to lay investiture in the Concordat of Worms (1122), the issue would flare up again.
