The Vatican has announced that the conclave to choose the successor to Pope Francis will begin on May 7, 2025. The decision follows the Pope’s passing on Easter Monday and his burial at the Basilica of Santa Maria Maggiore in Rome on Saturday.
The term “conclave,” derived from the Latin for “with key,” refers to the cardinals’ seclusion during the voting process. This period of papal vacancy, known as sede vacante—meaning “empty seat”—officially began after the Pope’s death.
In accordance with tradition, the Pope’s official ring and seal, used to authenticate documents, have been ceremonially destroyed to prevent misuse during the transition.
The start date for the conclave was confirmed during the fifth general congregation of cardinals held Monday morning in the Vatican’s Synod Hall. The gathering followed the completion of the Novemdiales, a nine-day period of mourning marked by daily Masses in honor of the late Pope.
The conclave will be held in the Sistine Chapel, which will be closed to the public throughout the proceedings. Before entering into isolation, the cardinal electors will attend a solemn Eucharistic celebration.
Of the 252 cardinals currently serving in the Catholic Church, 135 are under the age of 80 and therefore eligible to vote. Once the conclave commences, these electors will remain within the Vatican until a new Pope is chosen.
