Pope Callixtus II or Callistus II, born Guy of Burgundy, was head of the Catholic Church and ruler of the Papal States from 1 February 1119 to his death in 1124. His pontificate was shaped by the Investiture Controversy, which he was able to settle through the Concordat of Worms in 1122.
Pope Urban IV, born Jacques Pantaléon, was the head of the Catholic Church and ruler of the Papal States from 29 August 1261 to his death. He was elected pope without being a cardinal; he was the first to be elected in such a way, and this would occur for only 3 more popes afterwards.
Pope Stephen IX was the head of the Catholic Church and ruler of the Papal States from 3 August 1057 to his death in 29 March 1058. He was a member of the Ardenne-Verdun family, who ruled the Duchy of Lorraine, and started his ecclesiastical career as a canon in Liège. He was invited to Rome by Pope Leo IX, who made him chancellor in 1051 and one of three legates to Constantinople in 1054. The failure of their negotiations with Patriarch Michael I Cerularius of Constantinople and Archbishop Leo of Ohrid led to the permanent East–West Schism. He continued as chancellor to the next pope, Victor II, and was elected abbot of the Benedictine monastery of Montecassino.
Pope Formosus was the bishop of Rome and ruler of the Papal States from 6 October 891 until his death on 4 April 896. His reign as pope was troubled, marked by interventions in power struggles over the Patriarchate of Constantinople, the Kingdom of West Francia, and the Holy Roman Empire. Because he sided with Arnulf of Carinthia against Lambert of Spoleto, Formosus's remains were exhumed and put on trial in the Cadaver Synod. Several of his immediate successors were primarily preoccupied by the controversial legacy of his pontificate.
Year 876 (DCCCLXXVI) was a leap year starting on Sunday of the Julian calendar.
Pope Nicholas I, called Nicholas the Great, was the bishop of Rome and ruler of the Papal States from 24 April 858 until his death. He is remembered as a consolidator of papal authority, exerting decisive influence on the historical development of the papacy and its position among the Christian nations of Western Europe. Nicholas I asserted that the pope should have suzerainty over all Christians, even royalty, in matters of faith and morals.
Pope John XV was the bishop of Rome and ruler of the Papal States from August 985 until his death. A Roman by birth, he was the first pope who canonized a saint. The origins of the investiture controversy stem from John XV's pontificate, when the dispute about the deposition of Archbishop Arnulf of Reims soured the relationship between the Capetian kings of France and the Holy See.
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. He eventually fell out with Marozia, who had him deposed, imprisoned, and finally murdered. John’s pontificate occurred during the period known as the Saeculum obscurum.
William of Modena, also known as William of Sabina, Guglielmo de Chartreaux, Guglielmo de Savoy, Guillelmus, was an Italian clergyman and papal diplomat. He was frequently appointed a legate, or papal ambassador by the popes Honorius III and Gregory IX, especially in Livonia in the 1220s and in the Prussian questions of the 1240s. Eventually he resigned his see to devote himself to these diplomatic issues. On 28 May 1244 he was created Cardinal-Bishop of Sabina by Pope Innocent IV. For a short time (1219–1222) he served also as Vice-Chancellor of the Holy Roman Church.

Victor IV was elected as a Ghibelline antipope in 1159, following the death of Pope Adrian IV and the election of Alexander III. His election was supported by Emperor Frederick Barbarossa. He took the name Victor IV, not acknowledging Antipope Victor IV of 1138, whose holding of the papal office was deemed illegitimate.
Albert Suerbeer was the first Archbishop of Riga in Livonia.
Ebbo or Ebo was the Archbishop of Rheims from 816 until 835 and again from 840 to 841. He was born a German serf on the royal demesne of Charlemagne. He was educated at his court and became the librarian and councillor of Louis the Pious, king of Aquitaine, son of Charlemagne. When Louis became emperor, he appointed Ebbo to the see of Rheims, then vacant after the death of Wulfaire.
Albero de Montreuil was Archbishop of Trier from 1132 to 1152 and is the subject of the Gesta Alberonis.
The Archdiocese of Sens and Auxerre is a Latin Archdiocese of the Catholic Church in France. The Archdiocese comprises the department of Yonne, which is in the region of Bourgogne. Traditionally established in sub-apostolic times, the diocese as metropolis of Quarta Lugdunensis subsequently achieved metropolitical status. For a time, the Archbishop of Sens held the title "Primate of the Gauls and Germania". Until 1622, the Metropolitan Archdiocese numbered seven suffragan (subordinate) dioceses: the dioceses of Chartres, Auxerre, Meaux, Paris, Orléans, Nevers and Troyes, which inspired the acronym CAMPONT. The Diocese of Bethléem at Clamecy was also dependent on the metropolitan see of Sens. On December 8, 2002, as part of a general reorganization of the dioceses of France undertaken, at least in part, to respond to demographic changes, the Archdiocese of Sens-Auxerre ceased to have metropolitan rank and became a suffragan of the Archdiocese of Dijon, which became the centre of a new ecclesiastical province for the Burgundy administrative region. Consequently the Archbishop of Sens-Auxerre no longer has the privilege of wearing the pallium.
Cuno of Praeneste was a German Cardinal and papal legate, an influential diplomatic figure of the early 12th century, active in France and Germany. He held numerous synods throughout Europe, and excommunicated the Emperor Henry V numerous times, in the struggle over the issue of lay investiture of ecclesiastical offices. He spent six years promoting the acceptance of Thurstan of York as archbishop by King Henry I of England, without making York subject to Canterbury. He was seriously considered for election to the papacy in 1119, which he refused.
The Concordat of 1161 was an agreement between the Kingdom of Hungary and the Papal States, signed by Géza II of Hungary and papal legate Pietro di Miso in late summer or early autumn 1161. The Hungarian monarch squeezed out significant church government concessions for himself in exchange for switching sides and pledging support for Pope Alexander III against the Ghibelline Antipope Victor IV.
