The1154papal election followed the death ofPope Anastasius IV and resulted in the election ofPope Adrian IV, the onlyEnglishman to becomepope.

Pope Anastasius IV died on 3 December 1154 inRome, at a very advanced age. TheCollege of Cardinals assembled inOld St. Peter's Basilica on the next day to elect his successor.On 4 December 1154 the cardinals unanimously electedCardinal-Bishop of Albano Nicholas Breakspeare, formerlegate inScandinavia (1152–1153).^[1] He took the name Adrian IV and wascrowned on 5 December 1154 in the Vatican Basilica. He is the only English pope in history.^[2]

There were probably 30 cardinals in the Sacred College of Cardinals at the beginning of December 1154,^[3] but it seems that no more than 25 (perhaps even fewer) participated in the election:

Five electors were created byPope Innocent II, four byPope Celestine II, five byPope Lucius II, eleven byPope Eugenius III.

At least five cardinals did not participate in this election. Cardinal Giacinto Bobone is known to have been inSpain at that time; he served there as papal legate from the spring of 1154 until the end of 1155.^[4] Cardinal Odone Bonecase was employed as legate in France in 1154/55.^[5] Gerard de Namur was legate in Germany,^[6] while Ildebrando in Lombardy.^[7] Abbot Rainaldo of Montecassino was not a resident of Roman Curia:^[8]
