First Council of the Lateran
Roman Catholic synod of 1123
The First Council of the Lateran was the 9th ecumenical council recognised by the Catholic Church. The first ecumenical council to be held in Western Europe and the first since the Great Schism of 1054, it was convoked by Pope Callixtus II in December 1122, immediately after the Concordat of Worms. The council sought to bring an end to the practice of the conferring of ecclesiastical benefices by people who were laymen, free the election of bishops and abbots from secular influence, clarify the separation of spiritual and temporal affairs, re-establish the principle that spiritual authority resides solely in the Church and abolish the claim of the Holy Roman Emperor to influence papal elections.
The council was significant in size: 300 bishops and more than 600 abbots assembled at Rome's Lateran Palace in March 1123, and Callixtus II presided in person. During the council, the decisions of the Concordat of Worms were read and ratified. Various other decisions were promulgated.
Background
The First Lateran Council was called by Pope Callixtus II whose reign began on 1 February 1119. It demarcated the end of the Investiture Controversy, which had begun before the time of Pope Gregory VII. The issues had been contentious and had continued with unabated bitterness for almost a century. Guido, as he had been called before his elevation to the papacy, was the son of William I, Count of Burgundy. He was closely connected with nearly all the royal houses of Europe on both sides of his family.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
