Editing Pope Innocent II (section)

===Struggle against the Antipope===
Anacletus had control of Rome, so Innocent II took ship for [[Pisa]], and thence sailed by way of [[Genoa]] to France, where the influence of [[Bernard of Clairvaux]] readily secured his cordial recognition by the clergy and the court.{{sfn|Robinson|1990|p=361}}{{sfn|Somerville|1970|p=101}} In October 1130, he was duly acknowledged by King [[Lothair III of Germany]] and his bishops at the synod of [[Würzburg]].{{sfn|Clark|2016|p=11}}{{sfn|Lees|1998|p=34}} In January 1131, he also had a favourable interview with [[Henry I of England]] at Chartres.{{sfn|Truax|2017|p=27}}

In August 1132, Lothar III undertook an expedition to Italy to set aside Anacletus as [[antipope]] and be crowned by Innocent. Anacletus and his supporters being in secure control of [[St. Peter's Basilica]], the coronation ultimately took place in the [[Lateran Basilica]] (4 June 1133), but otherwise the expedition proved abortive. Innocent II invested Lothair as emperor and the territories belonging to [[Matilda of Tuscany]] in return for an annuity of 100 pounds of silver paid to the pope.{{sfn|Robinson|1990|p=246}} After Lothar's hasty departure from Rome, Innocent fled to Pisa.{{sfn|Somerville|1970|p=100-101}}

In May 1135, Innocent convened the [[Council of Pisa (1135)|council of Pisa]], which was attended by over one hundred clerics and abbots.{{sfn|Robinson|1990|p=138}} Innocent II had the council declare [[antipope Anacletus II]] and his supporters excommunicated.{{sfn|Robinson|1990|p=138}} The second expedition by Lothar III in 1136 was no more decisive in its results, and the protracted struggle between the rival pontiffs was terminated only by the death of Anacletus II on 25 January 1138.
