Charlemagne was King of the Franks from 768, King of the Lombards from 774, and Emperor of what is now known as the Carolingian Empire from 800, holding these titles until his death in 814. He united most of Western and Central Europe, and was the first recognised emperor to rule from the west after the fall of the Western Roman Empire approximately three centuries earlier. Charlemagne's reign was marked by political and social changes that had lasting influence on Europe throughout the Middle Ages.
Filioque, a Latin term meaning "and from the Son", was added to the original Nicene Creed, and has been the subject of great controversy between Eastern and Western Christianity. The term refers to the Son, Jesus Christ, with the Father, as the one shared origin of the Holy Spirit. It is not in the original text of the Creed, attributed to the First Council of Constantinople (381), which says that the Holy Spirit proceeds "from the Father" without the addition "and the Son".
The Liber Pontificalis is a book of biographies of popes from Saint Peter until the 15th century. The original publication of the Liber Pontificalis stopped with Pope Adrian II (867–872) or Pope Stephen V (885–891), but it was later supplemented in a different style until Pope Eugene IV (1431–1447) and then Pope Pius II (1458–1464). Although quoted virtually uncritically from the 8th to 18th centuries, the Liber Pontificalis has undergone intense modern scholarly scrutiny. The work of the French priest Louis Duchesne, and of others has highlighted some of the underlying redactional motivations of different sections, though such interests are so disparate and varied as to render improbable one popularizer's claim that it is an "unofficial instrument of pontifical propaganda."
Pope Adrian I was the bishop of Rome and ruler of the Papal States from 1 February 772 until his death. He was the son of Theodore, a Roman nobleman.
Pope Adrian II was the bishop of Rome and ruler of the Papal States from 867 to his death. He continued the policy of his predecessor, Nicholas I. Despite seeking good relations with Louis II of Italy, he was placed under surveillance, and his wife and daughters were killed by Louis' supporters.
Pope Benedict III was the bishop of Rome and ruler of the Papal States from 29 September 855 to his death.
Pope Stephen IV was the bishop of Rome and ruler of the Papal States from June 816 to his death. Stephen belonged to a noble Roman family. In October 816, he crowned Louis the Pious as emperor at Reims, and persuaded him to release some Roman political prisoners he held in custody. He returned to Rome, by way of Ravenna, sometime in November and died the following January.
Pope Zachary was the bishop of Rome from 28 November 741 to his death. He was the last pope of the Byzantine Papacy. Zachary built the original church of Santa Maria sopra Minerva, forbade the traffic of slaves in Rome, negotiated peace with the Lombards, and sanctioned Pepin the Short's usurpation of the Frankish throne from Childeric III. Zachary is regarded as a capable administrator and a skillful and subtle diplomat in a dangerous time.
Pope Eugene II was the bishop of Rome and ruler of the Papal States from 6 June 824 to his death. A native of Rome, he was chosen by nobles to succeed Paschal I as pope despite the clergy and the people favoring Zinzinnus. The influence of the Carolingian Franks on the selection of popes was then firmly established. Pope Eugene convened a council at Rome in 826 to condemn simony and suspend untrained clergy. It was decreed that schools were to be established at cathedral churches and other places to give instruction in sacred and secular literature. His involvement in the Byzantine Iconoclasm controversy was largely inconsequential.
Pope Paschal I was the bishop of Rome and ruler of the Papal States from 25 January 817 to his death in 824.
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.
Anastasius Bibliothecarius was the librarian (bibliothecarius) and chief archivist of the Church of Rome and also briefly a claimant to the Papacy.
The selection of the Pope, the Bishop of Rome and Supreme Pontiff of the Catholic Church, prior to the promulgation of In Nomine Domini in AD 1059 varied throughout history. Popes were often putatively appointed by their predecessors or by political rulers. While some kind of election often characterized the procedure, an election that included meaningful participation of the laity was rare, especially as the Popes' claims to temporal power solidified into the Papal States. The practice of papal appointment during this period would later result in the putative jus exclusivae, i.e., the claimed but invalid right to veto the selection that Catholic monarchs exercised into the twentieth century.
A number of significant councils of the Latin Church were held at Aachen in the early Middle Ages.
In the 9th century, Christianity was spreading throughout Europe, being promoted especially in the Carolingian Empire, its eastern neighbours, Scandinavia, and northern Spain. In 800, Charlemagne was crowned as Holy Roman Emperor, which continued the Photian schism.
From 756 to 857, the papacy shifted from the influence of the Byzantine Empire to that of the kings of the Franks. Pepin the Short, Charlemagne, and Louis the Pious had considerable influence in the selection and administration of popes. The "Donation of Pepin" (756) ratified a new period of papal rule in central Italy, which became known as the Papal States.
The history of the filioque controversy is the historical development of theological controversies within Christianity regarding three distinctive issues: the orthodoxy of the doctrine of procession of the Holy Spirit as represented by the Filioque clause, the nature of anathemas mutually imposed by conflicted sides during the Filioque controversy, and the liceity (legitimacy) of the insertion of the Filioque phrase into the Nicene Creed. Although the debates over the orthodoxy of the doctrine of procession and the nature of related anathemas preceded the question of the admissibility of the phrase as inserted into the Creed, all of those issues became linked when the insertion received the approval of the Pope in the eleventh century.
The Council of Constantinople of 867 was a major Church Council, convened by Emperor Michael III of Byzantium and Patriarch Photios I of Constantinople in order to address several ecclesiastical issues, including the question of Papal supremacy in the Church, and the use of Filioque clause in the Creed.
George was a Franco-papal diplomat who served as the bishop of Ostia (753–798) in the Papal State and bishop of Amiens (767–798) in Francia. He moved extensively between Italy and Francia, but his best recorded mission is the one he made to England in 786.
An earthquake originating in the Central Apennines was felt in Rome and Spoleto on 29 April 801. It is reported in two independent contemporary sources, Einhard's Royal Frankish Annals and the Liber Pontificalis. The information provided by the written sources has been augmented by archaeology.
