Aconclave was held from 21 to 22 January 1276 to elect the successor ofPope Gregory X, who succumbed to illness on the return from theSecond Ecumenical Council of Lyon. During the two day conclave, theDominican friar andcardinal Peter of Tarentaise,bishop of Ostia, was electedpope and took the nameInnocent V.

It was the first conclave held under the rules of constitutionUbi periculum, issued byPope Gregory X in 1274, which establishedpapal conclaves. According toUbi periculumcardinals were to be secluded in a closed area; they were not even accorded separate rooms. No cardinal was allowed to be attended by more than one servant unless ill. Food was to be supplied through a window; after three days of the meeting, the cardinals were to receive only one dish a day; after five days, they were to receive just bread and water. During the conclave, no cardinal was to receive any ecclesiastical revenue. These provisions were regularly disregarded, at the discretion of the cardinals, particularly the requirement of being incommunicado.

Although several times before papal elections were held in the circumstances similar to those described byUbi periculum,^[1] for the first time such situation was formally required by a papal Constitution. For this reason, the conclave of January 1276 can be considered the first conclave in history in the strictly legal sense of this word.

Pope Gregory X died on January 10, 1276, atArezzo. At the time of his death there were probably 15 cardinals in theSacred College, but only 13 of them participated in the subsequent conclave. Seven of them were created byUrban IV, four byGregory X and one byGregory IX:

Two cardinals were absent, including one created by Urban IV and one created byInnocent IV:

On January 20, 10 days after the death of Gregory X, 15 cardinals assembled in the episcopal palace inArezzo. In the first scrutiny on the following day they unanimously elected French CardinalPierre de Tarentaise,bishop of Ostia e Velletri, who took the name ofInnocent V. He was the firstDominican pope.
