Early in church history, thearchpriest,archdeacon, and "primicerius of the notaries"[clarification needed] in the papal court made a regency council which governed thesede vacante period.[2]
It was the obligation of theCamerarius (papal chamberlain), the head of theCamera Apostolica, to formally establish the death of the pope. Gradually, this led to the theory that the Camerarius, as the chief of the curia, should conduct normal business even after the death of the pope, and also conduct the burial and the preparation for the new election. This process was evident with CamerariusBoso Breakspeare.[3] During the longsede vacante of 1268 to 1271, the importance of the Camerarius was so clear that the Cardinals prepared to elect a new one if he died.[3]
According toUniversi Dominici gregis, the government of theHoly See and the administration of the Catholic Church during sede vacante falls to theCollege of Cardinals, but in a very limited capacity. At the same time, all the heads of the departments of theRoman Curia "cease to exercise" their offices. The exceptions are theCardinal Camerlengo, who is charged with managing the property of the Holy See, and theMajor Penitentiary, who continues to exercise his normal role. If either has to do something which normally requires the assent of the Pope, he has to submit it to the College of Cardinals.Papal legates continue to exercise their diplomatic roles overseas, and both theVicar General of Rome and theVicar General for the Vatican City State continue to exercise their pastoral role during this period. Thepostal administration of theVatican City State prepares and issues special postage stamps for use during this particular period, known as "sede vacante stamps".

Thecoat of arms of the Holy See also changes during this period. Thepapal tiara over thekeys is replaced with theumbraculum, orombrellino inItalian. This symbolizes both the lack of a Pope and the governance of the Camerlengo over thetemporalities of the Holy See. As further indication, the Camerlengo ornaments hisarms with this symbol during this period, which he subsequently removes once a pope is elected. Previously during this period the arms of the Camerlengo appeared on commemorativeVatican lira coinage. It now makes its appearance onVatican euro coins, which are legal tender in allEurozone states.
Theinterregnum is usually highlighted by thefuneralMass of the deceased pope, the general congregations of the College of Cardinals for determining the particulars of the election, and finally culminating in thepapal conclave to elect a successor. Once a newpope has been elected (andordained bishop if necessary) thesede vacante period officially ends, even before thepapal inauguration.
Cardinals present in Rome are required to wait at least fifteen days after the start of the vacancy before they hold the conclave to elect the new Pope. After twenty days have elapsed, they must hold the conclave, even if some cardinals are missing. The period from the death of the Pope to the start of the conclave was often shorter but, afterWilliam Henry Cardinal O'Connell had arrived just too late for two conclaves in a row,Pius XI extended the time limit. With the next conclave in 1939, cardinals began to travel by air. Days before his resignation in February 2013,Benedict XVI amended the rules to allow the cardinals to begin the conclave sooner, if all voting cardinals are present.[4] Historically,sede vacante periods have often been quite lengthy, lasting many months, or even years, due to lengthy deadlocked conclaves.
The most recent period ofsede vacante of the Holy See began on 28 February 2013, after the resignation of Benedict XVI,[5] and ended on 13 March 2013 with the election of Pope Francis, a period of 13 days.
The longest period without a Pope in the last 250 years was the approximately half year from the death in prison ofPius VI in 1799 and the election ofPius VII in Venice in 1800.
Whilst conclaves and papal elections are generally completed in short order, there have been several periods when the papal chair has been vacant for months or even years.
The following table detailssede vacante periods in excess of a year:
The termsede vacante can be applied to Catholic dioceses, archdioceses, andeparchies outside of Rome. In such cases, this means that the particular diocesanbishop orarchbishop has either died, resigned, been transferred to a different diocese or archdiocese, or lost his office and a successor has not yet beeninstalled or assumed office. If there is acoadjutor bishop for the (arch)diocese, then this period does not take place, as the coadjutor bishop or archbishop immediately succeeds to theepiscopal see.
Within eight days after the episcopal see is known to be vacant, the college ofconsultors (or thecathedral chapter in some countries)[7] is obliged to elect adiocesan or archdiocesan administrator.[8] The administrator they choose must be a/an priest or (arch)bishop who is at least 35 years old.[9]
If the college of consultors fails to elect a qualifying person within the time allotted, the choice of an administrator passes to themetropolitan archbishop or, if the metropolitan see is vacant, to the senior-most by appointment of thesuffragan bishops. Thepope can also decide to name an administrator himself to a diocese or archdiocese instead of waiting for the college of consultors of a particular (arch)diocese, metropolitan archbishop or the senior-most by appointment of the bishops within the ecclesiastical province to appoint a/an (arch)diocesan administrator where it is then called asapostolic administrator. Usually, the emeritus (arch)bishop will be appointed in such a case. If the appointed apostolic administrator is a diocesan bishop or archbishop of a diocese or archdiocese, then he governs two (arch)dioceses which are his own and the vacant one, with the latter being temporarily while a successor of a vacant (arch)diocese is not yet installed or assumed office.[10]
Before the election of the administrator of a vacant see, the governance of the see is entrusted, with the powers of avicar general, to theauxiliary bishop, if there is one, or to the senior among them, if there are several, otherwise to the college of consultors as a whole. The administrator has greater powers, essentially those of a bishop or archbishop except for matters excepted by the nature of the matter or expressly by law.[11] Canon law subjects his activity to various legal restrictions and to special supervision by the college of consultors (as for example canons 272 and 485).
Vicars general and episcopal vicars lose their powerssede vacante if they are not bishops or archbishops;[12] the vicars that are themselves having both positions retain the powers they had before the see fell vacant, which they are to exercise under the authority of the administrator.[13] However, vicar generals retain their duties and responsibilities of the office—specifically during sede vacante serving as right-hand to the(arch)diocesan orapostolic administrator to establish continuity—until the succeeding (arch)bishop is installed or assumes office on a/an (arch)diocese.
Acoat of arms of the last bishop or archbishop of a diocese or archdiocese, either the arms of a transferred, retired or died previous (arch)bishop or the one as (arch)bishop of a transferred (arch)diocese, may also be used during sede vacante period to indicate and establish continuity while awaiting for the installation of a successor. Once a successor is installed or assumed office which ends the sede vacante period, the coat of arms of a new (arch)bishop will then be used by the (arch)diocese and discontinuing the usage of the predecessor's arms.
The name of a bishop or an archbishop is not mentioned in the Eucharistic Prayer while a successor is not yet installed or assumed office where after mentioning thePope, the celebrant will either immediately mention the statement "and all the clergy" skipping the name of a/an (arch)bishop or generally stating all the (arch)bishops as "the Order of Bishops". If a locally-appointed (arch)diocesan administrator or anapostolic administrator is a/an (arch)bishop, however, the name of an administrator is mentioned ("our Administrator", or simply as "our (Arch)bishop") as if a/an (arch)diocese have a prelate installed in office.
Additionally, the administrator cannot use thecathedra even if he is a bishop or an archbishop as it symbolizes the office of a full-time or mainstay prelate and the former only serves as the temporary head of a/an (arch)diocese while a successor is not yet installed into office therefore he can only use the chair reserved for the main celebrant of a mass.
^As is usual in English, in canon law also (Code of Canon Law, canon 203), the initial day is not counted in calculating the length of a period, unless the period began with the beginning of the day.
