Papal conclave

As early Christian communities emerged, they elected bishops, chosen by the clergy and laity with the assistance of the bishops of neighbouring dioceses.[4] Cyprian (died 258) says that Pope Cornelius (in office 251–253) was chosen as Bishop of Rome "by the decree of God and of His Church, by the testimony of nearly all the clergy, by the college of aged bishops [sacerdotum], and of good men".[14] As in other dioceses, the clergy of the Diocese of Rome was the electoral body for the Bishop of Rome. Instead of casting votes, the bishop was selected by general consensus or by acclamation. The candidate was then submitted to the people for their general approval or disapproval. This lack of precision in the election procedures occasionally gave rise to rival popes or antipopes.[15]

The right of the laity to reject the person elected was abolished by a Synod held in the Lateran in 769, but restored to Roman noblemen by Pope Nicholas I during a Synod of Rome in 862.[15] The pope was also subjected to oaths of loyalty to the Holy Roman Emperor, who had the duty of providing security and public peace in Rome.[16] A major change came in 1059, when Pope Nicholas II decreed in In Nomine Domini that the cardinals were to elect a candidate to take office after receiving the assent of the clergy and laity. The cardinal bishops were to meet first and discuss the candidates before summoning the cardinal priests and cardinal deacons for the actual vote.[14] The Second Council of the Lateran in 1139 removed the requirement for obtaining the assent of the lower clergy and the laity,[15] while the Third Council of the Lateran in 1179 gave equal rights to the entire College of Cardinals when electing a new pope.[17]

Through much of the Middle Ages and Renaissance the Catholic Church had only a small number of cardinals at any one time, as few as seven under either Pope Alexander IV (1254–1261)[18] or Pope John XXI (1276–1277).[19][20] The difficulty of travel further reduced the number arriving at conclaves. The small electorate magnified the significance of each vote and made it all but impossible to displace familial or political allegiances. Conclaves lasted months and even years. In his 1274 decree requiring the electors be locked in seclusion, Gregory X also limited each cardinal elector to two servants and rationed their food progressively when a conclave reached its fourth and ninth days.[15] The cardinals disliked these rules; Pope Adrian V temporarily suspended them in 1276 and John XXI's Licet felicis recordationis revoked them later that same year.[21][lower-alpha 1] Lengthy elections resumed and continued to be the norm until 1294, when Pope Celestine V reinstated the 1274 rules.[22] Long interregna followed: in 1314–1316 during the Avignon Papacy, where the original conclaves were dispersed by besieging mercenaries and not reconvened for almost two years;[23] and in 1415–1417, as a result of the Western Schism.

It is noteworthy that until 1899, it was a regular practice to generally include a few lay members in the Sacred College. These were often prominent nobility, or monks who were not priests, and in all cases, celibacy was required. With the death of Teodolfo Mertel in 1899, this practice was ended.[24] In 1917, the Code of Canon Law promulgated that year, explicitly stated that all cardinals must be priests. Since 1962, all cardinals have been bishops, with the exception of a few priests who were made cardinals after 1975 and being 80 years of age or older, were dispensed from the requirement of episcopal ordination. It was in 1975, that Paul VI decreed that those 80 years of age or older, were not allowed to vote in papal conclaves.

In 1587 Pope Sixtus V limited the number of cardinals to 70, following the precedent of Moses who was assisted by 70 elders in governing the Children of Israel: six cardinal bishops, 50 cardinal priests, and 14 cardinal deacons.[18] Beginning with the attempts of Pope John XXIII (1958–1963) to broaden the representation of nations in the College of Cardinals, that number has increased. In 1970 Paul VI ruled that cardinals who reach the age of eighty before the start of a conclave are ineligible to participate.[25] In 1975 he limited the number of cardinal electors to 120.[26] Though this remains the theoretical limit, all of his successors have exceeded it for short periods of time. John Paul II (in office 1978–2005) also changed the age limit slightly, so that cardinals who turn 80 before a papal vacancy (not before conclave start) can not serve as electors;[3] this eliminated the idea of scheduling the conclave to include or exclude a cardinal who is very close to the age limit (and in 2013, Cardinal Walter Kasper, 79 when the papacy became vacant, participated in the conclave at age 80).

Originally, lay status did not bar election to the See of Rome. Bishops of dioceses were sometimes elected while still catechumens, such as the case of St. Ambrose,[27] who became Bishop of Milan in 374. In the wake of the violent dispute over the 767 election of Antipope Constantine II, Pope Stephen III held the synod of 769, which decreed that only a cardinal priest or cardinal deacon could be elected, specifically excluding those that are already bishops.[14][28] Church practice deviated from this rule as early as 817 and fully ignored it from 882 with the election of Pope Marinus I, the Bishop of Caere.[29] Nicholas II, in the synod of 1059, formally codified existing practice by decreeing that preference was to be given to the clergy of Rome, but leaving the cardinal bishops free to select a cleric from elsewhere if they so decided.[30] The Council of 1179 rescinded these restrictions on eligibility.[17] On 15 February 1559, Paul IV issued the Papal Bull Cum ex apostolatus officio, a codification of the ancient Catholic law that only Catholics can be elected Popes, to the exclusion of non-Catholics, including former Catholics who have become public and manifest heretics.

Pope Urban VI in 1378 became the last pope elected from outside the College of Cardinals.[31] The last person elected as pope who was not already an ordained priest or deacon was the cardinal-deacon Giovanni di Lorenzo de' Medici, elected as Pope Leo X in 1513.[32] His successor, Pope Adrian VI, was the last to be elected (1522) in absentia.[33] Archbishop Giovanni Montini of Milan received several votes in the 1958 conclave though not yet a cardinal.[34][35] As the Catholic Church holds that women cannot be validly ordained, women are not eligible for the papacy.[lower-alpha 2] Though the pope is the Bishop of Rome, he need not be of Italian background. As of 2017, the three most recent conclaves have elected a Pole (1978), a German (2005), and an Argentinian (2013).

A simple majority vote sufficed until 1179, when the Third Council of the Lateran increased the required majority to two-thirds.[11] As cardinals were not allowed to vote for themselves (after 1621), the ballots were designed to ensure secrecy while at the same time preventing self-voting.[lower-alpha 3] In 1945 Pope Pius XII removed the prohibition on a cardinal voting for himself, increasing the requisite majority to two-thirds plus one at all times.[40] He eliminated as well the need for signed ballots.[41] His successor John XXIII immediately reinstated the two-thirds majority if the number of cardinal electors voting is divisible by three, with a rounding up to two-thirds plus one otherwise.[lower-alpha 4] Paul VI reinstated Pius XII's procedure thirteen years later,[26] but John Paul II overturned it again. In 1996, John Paul II's constitution allowed election by absolute majority if deadlock prevailed after thirty-three or thirty-four ballots[3] (thirty-four ballots if a ballot took place on the first afternoon of the conclave). In 2007 Benedict XVI rescinded John Paul II's change (which effectively abolished the two-thirds majority requirement, as any majority suffices to block the election until a simple majority is enough to elect the next pope), reaffirming the requirement of a two-thirds majority.[7][8]

Electors formerly made choices by accessus, acclamation (per inspirationem), adoration, compromise (per compromissum) or scrutiny (per scrutinium).[9]

• Accessus was a method for cardinals to change their most recent vote to accede to another candidate in an attempt to reach the requisite two-thirds majority and end the conclave. This method was first disallowed by the Cardinal Dean at the 1903 conclave.[9]
• With acclamation, the cardinals unanimously declared the new pope quasi afflati Spiritu Sancto (as if inspired by the Holy Spirit).[40] If this took place before any formal ballot has taken place, the method was called adoration,[42] but Pope Gregory XV excluded this method in 1621.[43][44]
• To elect by compromise, a deadlocked College unanimously delegates the election to a committee of cardinals whose choice they all agree to abide by.[40]
• Scrutiny is election via the casting of secret ballots.

The last election by compromise is considered to be that of Pope John XXII in 1316, and the last election by acclamation that of Pope Innocent XI in the 1676 conclave.[45] Universi Dominici gregis formally abolished the long unused methods of acclamation and compromise in 1996, making scrutiny now the only approved method for the election of a new pope.[3]

For a significant part of the Church's history, powerful monarchs and governments influenced the choice of its leaders. For example, the Roman emperors once held considerable sway in the elections of popes. In 418, Emperor Honorius settled a controversial election, upholding Pope Boniface I over the challenger Antipope Eulalius. On the request of Boniface I, Honorius ordered that in future cases, any disputed election would be settled by a fresh election.[46] After the demise of the Western Roman Empire, influence passed to the Ostrogothic Kings of Italy and in 533, Pope John II formally recognised the right of the Ostrogothic monarchs to ratify elections. By 537 the Ostrogothic monarchy had been overthrown, and power passed to the Byzantine emperors. A procedure was adopted whereby officials were required to notify the Exarch of Ravenna upon the death of a pope before proceeding with the election.[47] Once the electors arrived at a choice, they were required to send a delegation to Constantinople requesting the emperor's consent, which was necessary before the individual elected could take office. Travel to and from Constantinople caused lengthy delays.[48] When Pope Benedict II (684-685) complained about them, Emperor Constantine IV (in office 654-685) acquiesced, ending the requirement for emperors to confirm elections. Thereafter, the Emperor was only required to be notified.[49] The last pope to notify a Byzantine emperor was Pope Zachary in 741.[50]

In the 9th century, the Holy Roman Empire came to exert control over papal elections. While Charlemagne (Emperor from 800 to 814) and Louis the Pious (Emperor from 813 to 840) did not interfere with the Church, Lothair I (Emperor from 817 to 855) claimed that an election could only take place in the presence of imperial ambassadors.[51] In 898 riots forced Pope John IX to recognise the superintendence of the Holy Roman Emperor.[52][53] At the same time, the Roman nobility also continued to exert great influence, especially during the tenth-century period known as saeculum obscurum (Latin for "the dark age").[54]

In 1059 the same papal bull that restricted suffrage to the cardinals also recognised the authority of the Holy Roman Emperor (at the time Henry IV), but only as a concession made by the pope, declaring that the Holy Roman Emperor had no authority to intervene in elections except where permitted to do so by papal agreements.[30] Pope Gregory VII (in office 1073-1085) was the last Pope to submit to the interference of the Holy Roman Emperors. The breach between him and the Holy Roman Empire caused by the Investiture Controversy led to the abolition of the Emperor's role.[55] In 1122 the Holy Roman Empire acceded to the Concordat of Worms, accepting the papal decision.[56]

From about 1600, certain Catholic monarchs claimed a jus exclusivae (right of exclusion), i.e. a veto over papal elections, exercised through a crown-cardinal. By an informal convention, each state claiming the veto could exercise the right once per conclave. Therefore, a crown-cardinal did not announce his veto until the very last moment when the candidate in question seemed likely to get elected. No vetoes could be employed after an election. After the Holy Roman Empire dissolved in 1806, its veto power devolved upon the Austrian Empire. The last exercise of the veto occurred in 1903, when Prince Jan Puzyna de Kosielsko informed the College of Cardinals that Austria opposed the election of Mariano Rampolla. Consequently, the College elected Giuseppe Sarto as Pope Pius X, who issued the Constitution Commissum nobis six months later, declaring that any cardinal who communicated his government's veto in the future would suffer excommunication latae sententiae.[57][58]

To resolve prolonged deadlocks in papal elections in the earlier years, local authorities often resorted to the forced seclusion of the cardinal electors, such as first in the city of Rome in 1241, and possibly before that in Perugia in 1216.[59] In 1269, when the forced seclusion of the cardinals alone failed to produce a pope, the city of Viterbo refused to send in any materials except bread and water. When even this failed to produce a result, the townspeople removed the roof of the Palazzo dei Papi in their attempt to speed up the election.[60]

In an attempt to avoid future lengthy elections, Gregory X introduced stringent rules with the 1274 promulgation of Ubi periculum. Cardinals were to be secluded in a closed area and not accorded individual rooms. No cardinal was allowed, unless ill, to be attended by more than two servants. Food was supplied through a window to avoid outside contact.[lower-alpha 5] After three days of the conclave, the cardinals were to receive only one dish a day; after another five days, they were to receive just bread and water. During the conclave, no cardinal was to receive any ecclesiastical revenue.[15][61]

Adrian V abolished Gregory X's strict regulations in 1276, but Celestine V, elected in 1294 following a two-year vacancy, restored them. In 1562 Pius IV issued a papal bull that introduced regulations relating to the enclosure of the conclave and other procedures. Gregory XV issued two bulls that covered the most minute of details relating to the election; the first, in 1621, concerned electoral processes, while the other, in 1622, fixed the ceremonies to be observed. In December 1904 Pope Pius X issued an apostolic constitution consolidating almost all the previous rules, making some changes, Vacante sede apostolica.[62] John Paul II instituted several reforms in 1996.[9]

The location of the conclaves became fixed in the fourteenth century. Since the end of the Western Schism in 1417, they have taken place in Rome (except in 1799–1800, when French troops occupying Rome forced the election to be held in Venice), and normally in what, since the Lateran Treaties of 1929, has become the independent Vatican City State. Since 1846, when the Quirinal Palace was used, the Sistine Chapel in the Vatican has served as the location of the election. Popes have often fine-tuned the rules for the election of their successors: Pope Pius XII's Vacantis Apostolicae Sedis (1945) governed the conclave of 1958, Pope John XXIII's Summi Pontificis electio (1962) that of 1963, Pope Paul VI's Romano Pontifici eligendo (1975) the two conclaves of 1978, John Paul II's Universi Dominici Gregis (1996) that of 2005, and two amendments by Benedict XVI (2007, 2013) that of 2013.

The camerlengo proclaiming a papal death

The death of the pope is verified by the cardinal camerlengo, or chamberlain, who traditionally performed the task by calling out his baptismal (not papal) name three times in the presence of the master of papal liturgical celebrations, and of the cleric prelates, secretary and chancellor of the Apostolic Camera. The camerlengo takes possession of the Ring of the Fisherman worn by the pope; the ring, along with the papal seal, is later destroyed before the College of Cardinals. The tradition originated to avoid forgery of documents, but today merely is a symbol of the end of the pope's reign.[66][67]

During the sede vacante, as the papal vacancy is known, certain limited powers pass to the College of Cardinals, which is convoked by the dean of the College of Cardinals. All cardinals are obliged to attend the general congregation of cardinals, except those whose health does not permit, or who are over eighty (but those cardinals may choose to attend if they please as non voting members). The particular congregation, which deals with the day-to-day matters of the Church, includes the cardinal camerlengo and the three cardinal assistants—one cardinal bishop, one cardinal priest and one cardinal deacon—chosen by lot. Every three days, new cardinal assistants are chosen by lot. The camerlengo and assistants are responsible, among other things, for maintaining the election's secrecy.[68]

The congregations must make certain arrangements in respect of the pope's burial, which by tradition takes place within four to six days of the pope's death, leaving time for pilgrims to see the dead pontiff, and occurs within a nine-day period of mourning known as the novemdiales, Latin for 'nine days'. The congregations also fix the date and time of the commencement of the conclave. The conclave normally takes place fifteen days after the death of the pope, but the Congregations may extend the period to a maximum of twenty days in order to permit other cardinals to arrive in the Vatican City.[69]

Cardinals, bishops and priests attending the funeral of Pope John Paul II

A vacancy in the papal office may also result from a papal resignation. Until the resignation of Benedict XVI on 28 February 2013, no pope had abdicated since Gregory XII in 1415.[70] In 1996 Pope John Paul II, in his Apostolic Constitution Universi Dominici gregis, anticipated the possibility of resignation when he specified that the procedures he set out in that document should be observed "even if the vacancy of the Apostolic See should occur as a result of the resignation of the Supreme Pontiff".[71]

In the case of a papal resignation, the Ring of the Fisherman is placed in the custody of the Cardinal Camerlengo; in the presence of the College of Cardinals, the Cardinal Camerlengo marks an X (for the cross) with a small silver hammer and chisel into the Ring, disfiguring it so it may no longer be used for signing and sealing official papal documents.

In his book, Light Of The World: The Pope, The Church and The Signs Of The Times, Benedict XVI espoused the idea of abdication on health grounds, which already had some theological respectability.[72]

The cardinals hear two sermons before the election: one before actually entering the conclave, and one once they are settled in the Sistine Chapel. In both cases, the sermons are meant to lay out the current state of the Church, and to suggest the qualities necessary for a pope to possess in that specific time. The first preacher in the 2005 conclave was Fr. Raniero Cantalamessa, the preacher of the papal household and a member of the Capuchin Franciscan order, who spoke at one of the meetings of the cardinals held before the actual day when the conclave began.[73] Cardinal Tomáš Špidlík, a former professor at the Pontifical Oriental Institute and a non-voting member (due to age) of the College of Cardinals, spoke just before the doors were finally closed for the conclave.[74]

On the morning of the day designated by the congregations of cardinals, the cardinal electors assemble in Saint Peter's Basilica to celebrate Mass. Then they gather in the afternoon in the Pauline Chapel in the Apostolic Palace and process to the Sistine Chapel while singing the Litany of the Saints. The cardinals will also sing the "Veni Creator Spiritus", invoking the Holy Spirit,[75] then take an oath to observe the procedures set down by the apostolic constitutions; to, if elected, defend the liberty of the Holy See; to maintain secrecy; and to disregard the instructions of secular authorities on voting. The senior cardinal reads the oath aloud in full; in order of precedence (where their rank is the same, their seniority is taken as precedence), the other cardinal electors repeat the oath, while touching the Gospels. The oath is:[76][77]

Et ego [given name] Cardinalis [surname] spondeo, voveo ac iuro. Sic me Deus adiuvet et haec Sancta Dei Evangelia, quae manu mea tango.

And I, [given name] Cardinal [surname], so promise, pledge and swear. So help me God and these Holy Gospels which I now touch with my hand.

After all the cardinals present have taken the oath, the master of papal liturgical celebrations orders all individuals other than the cardinal electors and conclave participants to leave the Chapel. Traditionally, he stands at the door of the Sistine Chapel and calls out: "Extra omnes!" (Latin for 'Outside, all [of you]'). He then closes the door.[78] In modern practice, the master of papal liturgical celebrations does not have to stand at the door of the Sistine Chapel—during the 2013 conclave, the Master Guido Marini stood in front of the altar and gave the command through a microphone and only went to the chapel doors to close them after the outsiders had left.[79][80]

The master himself may remain, as may one ecclesiastic designated by the congregations prior to the commencement of the election. The ecclesiastic makes a speech concerning the problems facing the Church and on the qualities the new pope needs to have. After the speech concludes, the ecclesiastic leaves. Following the recitation of prayers, the senior cardinal asks if any doubts relating to procedure remain. After the clarification of the doubts, the election may commence. Cardinals who arrive after the conclave has begun are admitted nevertheless. A sick cardinal or a cardinal who has to use the lavatory may leave the conclave and later be readmitted; a cardinal who leaves for any reason other than illness may not return to the conclave.[81]

Although in the past cardinal electors could be accompanied by attendants ("conclavists"), now only a nurse may accompany a cardinal who for reasons of ill-health, as confirmed by the Congregation of Cardinals, needs such assistance.[3] The Secretary of the College of Cardinals, the master of papal liturgical celebrations, two masters of ceremonies, two officers of the Papal Sacristy and an ecclesiastic assisting the dean of the College of Cardinals are also admitted to the conclave. Priests are available to hear confessions in different languages; two doctors are also admitted. Finally, a strictly limited number of servant staff are permitted for housekeeping and the preparing and serving of meals.

Secrecy is maintained during the conclave; the cardinals as well as the conclavists and staff are forbidden to disclose any information relating to the election. Cardinal electors may not correspond or converse with anyone outside the conclave, by post, radio, telephone, internet, social media or otherwise, and eavesdropping is an offense punishable by automatic excommunication (latae sententiae). Only three cardinal electors are permitted to communicate with the outside world under grave circumstances, prior to approval of the College, to fulfill their duties: the Major Penitentiary, the Cardinal Vicar for the Diocese of Rome, and the Vicar General for the Vatican City State.[3]

Before the conclave that elected Pope Francis, the Sistine Chapel was "swept" using the latest electronic devices to detect any hidden "bugs" or surveillance devices (there were no reports that any were found, but in previous conclaves press reporters who had disguised themselves as conclave servants were discovered). Universi Dominici gregis specifically prohibits media such as newspapers, the radio, and television.[82] Wi-Fi access is blocked in Vatican City and wireless signal jammers are deployed at the Sistine Chapel to prevent any form of electronic communications to or from the cardinal electors.[83]

Cardinals formerly used these intricate ballot papers, one of which is shown folded above. Currently, the ballots are simple cards, folded once (like a note card), with the words "I elect as Supreme Pontiff" printed in Latin on them.

Today, cardinal electors receive copies of multiple ballot cards, scrutiny ballots, and a copy of Ordo Rituum Conclavis (Order of Conclave Rites). Shown above are the ballot papers of Cardinal Roger Mahony used in the 2013 conclave.

On the afternoon of the first day, one ballot (referred to as a "scrutiny") may be held, but is not required. If a ballot takes place on the afternoon of the first day and no-one is elected, or no ballot had taken place, a maximum of four ballots are held on each successive day: two in each morning and two in each afternoon. Before voting in the morning and again before voting in the afternoon, the electors take an oath to obey the rules of the conclave. If no result is obtained after three vote days of balloting, the process is suspended for a maximum of one day for prayer and an address by the senior cardinal deacon. After seven further ballots, the process may again be similarly suspended, with the address now being delivered by the senior cardinal priest. If, after another seven ballots, no result is achieved, voting is suspended once more, the address being delivered by the senior cardinal bishop. After a further seven ballots, there shall be a day of prayer, reflection and dialogue. In the following ballots, only the two names who received the most votes in the last ballot shall be eligible in a runoff election where a two-thirds majority is still required. The two people voted on, if cardinal electors, shall not themselves have the right to vote.[7]

The process of voting comprises three phases: the "pre-scrutiny", the "scrutiny", and the "post-scrutiny".

During the pre-scrutiny, the masters of ceremonies prepare ballot papers bearing the words Eligo in Summum Pontificem ("I elect as Supreme Pontiff") and provide at least two to each cardinal elector. As the cardinals begin to write down their votes, the secretary of the College of Cardinals, the master of papal liturgical celebrations and the masters of ceremonies exit; the junior cardinal deacon then closes the door. The junior cardinal deacon then draws by lot nine names; the first three become scrutineers, the second three infirmarii and the last three revisers. New scrutineers, infirmarii and revisers are not selected again after the first scrutiny; the same nine cardinals perform the same task for the second scrutiny. After lunch, the election resumes with the oath to obey the rules of the conclave taken anew when the cardinals again assemble in the Sistine Chapel. Nine names are chosen for new scrutineers, infirmarii, and revisers. The third scrutiny then commences, and if necessary, a fourth immediately follows.[84] No changes in these rules were made by Benedict XVI in 2007. These rules were followed (so far as is known, given the secrecy of a conclave) in electing Pope Francis in March 2013.

The scrutiny phase of the election is as follows: The cardinal electors proceed, in order of precedence, to take their completed ballots (which bear only the name of the individual voted for) to the altar, where the scrutineers stand. Before casting the ballot, each cardinal elector takes the following Latin oath:

Testor Christum Dominum, qui me iudicaturus est, me eum eligere, quem secundum Deum iudico eligi debere.

I call as my witness Christ the Lord who will be my judge, that my vote is given to the one who before God I think should be elected.

If any cardinal elector is in the chapel, but cannot proceed to the altar due to infirmity, the last scrutineer may go to him and take his ballot after the oath is recited. If any cardinal elector is by reason of infirmity confined to his room, the infirmarii go to their rooms with ballot papers and a box. Any such sick cardinals complete the ballot papers and then take the oath and drop the ballot papers into the box. When the infirmarii return to the chapel, the ballots are counted to ensure that their number matches with the number of ill cardinals; thereafter, they are deposited in the appropriate receptacle. This oath is taken by all cardinals as they cast their ballots. If no one is chosen on the first scrutiny, then a second scrutiny immediately follows. A maximum total of four scrutinies can be taken each day, two in the morning and two in the afternoon.

The oath when casting one's vote is anonymous, since the name of the elector is no longer signed on the ballot with that of the candidate. (Previously, the ballot was signed by the elector, who included his motif [unique identification code]. Then he folded it over at two places to cover his signature and motif. After this, it was sealed with wax to result in a semi-secret ballot.) This was the procedure prior to 1945. The example above is a copy of the old three section semi-secret ballot, which was last used in the conclave of 1939. There was no oath taken when actually casting ballots, prior to 1621.[85] Completely secret ballots (at the option of the cardinals present and voting) were sometimes used prior to 1621, but these secret ballots had no oath taken when the vote was actually cast. At some conclaves prior to 1621, the cardinals verbally voted and sometimes stood in groups to facilitate counting the votes cast. The signature and motif of the elector covered by two folded-over parts of the ballot paper was added by Gregory XV in 1621, to prevent anyone from casting the deciding vote for himself. Cardinal Pole of England refused to cast the deciding vote for himself in 1549, which would then have been followed by the accession (and was not elected), but in 1492 Cardinal Borgia (Pope Alexander VI) almost certainly did privately bribe other cardinals to vote for him. It is rather certain that he would not have been allowed to cast the deciding vote for himself. A procedure called accession gave electors who had not voted for the possible new pope the opportunity to change their votes and make the election unanimous (or nearly so), except for the vote of possible new pope. [86] Faced by the mortal challenge to the papacy emanating from Protestantism, and fearing schism due to several stormy conclaves in the late 16th and early 17th centuries, Gregory XV established the procedure of signed ballots to prevent any cardinal from casting the deciding vote for himself. The accession was not ended, but seldom used until Pius XII abolished it in 1945. [87] Since 1945, a cardinal can cast the deciding vote for himself without the accession, though the two-thirds majority rule has always been continued, except when John Paul II had modified that rule in 1996 (after 33 ballots, a simple majority was sufficient), with the two-thirds majority rule restored in 2007 by Benedict XVI.[88]

Prior to 1621, the only oath taken was that of obedience to the rules of the conclave in force at that time, when the cardinals entered the conclave and the doors were locked, and each morning and afternoon as they entered the Sistine Chapel to vote. Gregory XV added the additional oath, taken when each cardinal casts his ballot, to prevent cardinals wasting time in casting "courtesy votes" and instead narrowing the number of realistic candidates for the papal throne to perhaps only two or three. Speed in electing a pope was important, and that meant using an oath so as to get the cardinals down to the serious business of electing a new pope and narrowing the number of potentially electable candidates. The reforms of Gregory XV in 1621 and reaffirmed in 1622 created the written detailed step-by-step procedure used in choosing a pope; a procedure that was essentially the same as that which was used in 2013 to elect Pope Francis. The biggest change since 1621 was the elimination of the rule that required the electors to sign their ballots resulting in the detailed voting procedure of scrutiny making use of anonymous oaths. Beginning in 1945, an elector could vote for himself and then call on God via the oath taken when the vote is dropped into the receptacle, to declare himself to be the best one qualified for the papacy.[89][90]

Once all votes have been cast, the first scrutineer chosen shakes the container, and the last scrutineer removes and counts the ballots. If the number of ballots does not correspond to the number of cardinal electors present (including sick cardinals in their rooms), the ballots are burnt, unread, and the vote is repeated. If no irregularities are observed, the ballots may be opened and the votes counted. Each ballot is unfolded by the first scrutineer; all three scrutineers separately write down the name indicated on the ballot. The last of the scrutineers reads the name aloud.

Once all of the ballots have been opened, the final post-scrutiny phase begins.

The scrutineers add up all of the votes, and the revisers check the ballots and the names on the scrutineers' lists to ensure that no error was made. The ballots are then all burned by the scrutineers with the assistance of the secretary of the College of Cardinals and the masters of ceremonies. If the first scrutiny held in any given morning or afternoon does not result in an election, the cardinals proceed to the next scrutiny immediately. The papers from both scrutinies are then burned together at the end of the second scrutiny.

Fumata nera in the Sistine Chapel, indicating that there was not a two-thirds majority in the papal election at the Conclave.[91]

Fumata bianca in Sistine Chapel, indicating that a pope has been elected by the College of Cardinals.[91]

Beginning in the early 1800s, the ballots used by cardinals were burned after each ballot to indicate a failed election.[92][93] The lack of smoke instead signalled a successful election.[94][92] Since 1914, black smoke (fumata nera) emerging from a temporary chimney installed on the roof of the Sistine Chapel indicates that the ballot did not result in an election, while white smoke (fumata bianca) announces that a new pope has been chosen.[91][95]

Prior to 1945 (when Pius XII changed the form of ballot to use unsigned ballots, first carried out in 1958), the sealing wax on the complex type ballots illustrated above had the effect of making the smoke from burning the ballots either black or white, depending on whether or not damp straw was added. Until the 20th century, sealing wax customarily had beeswax mixed into its composition. The use of wax made solely from animal fat does not give as much white colored smoke, as does wax that includes beeswax. In the 1939 conclave there was some confusion over the smoke color, which was even more apparent in the 1958 conclave. The lack of sealing wax on the ballots explains the confusion over the color of the smoke in the 1958 conclave. The Siri thesis was based on the confusion over the smoke color on the first day of that conclave.

Since 1963, chemicals have been added to the burning process to augment the smoke's black or white color. Beginning in 2005, a successful election is also accentuated by bells ringing at the appearance of the white smoke.[96]

During the 2013 conclave, the Vatican disclosed the chemicals used to color the smoke:[97][98][99]

• Black smoke: potassium perchlorate, anthracene, sulfur
• White smoke: potassium chlorate, lactose, pine rosin

Once the election concludes, the cardinal dean summons the secretary of the College of Cardinals and the master of papal liturgical celebrations into the hall. The dean then asks the pope-elect if he assents to the election, saying in Latin: Acceptasne electionem de te canonice factam in Summum Pontificem? ('Do you accept your canonical election as Supreme Pontiff?') There is no requirement that the pope-elect do so, and he is free to respond Non accepto ('I do not accept').

In practice, any cardinal who intends not to accept will explicitly state this before he receives a sufficient number of votes to become pope, as Giovanni Colombo did in October 1978.[100][101]

If he accepts, and is already a bishop, he immediately takes office. If he is not a bishop, he must be first consecrated as one before he can assume office. If a priest is elected, the dean of the College of Cardinals consecrates him bishop; if a layman is elected, then the dean first ordains him deacon, then priest, and only then consecrates him as bishop. Only after becoming a bishop does the pope-elect take office. These functions of the dean are assumed, if necessary, by the sub-dean, and if the sub-dean is also impeded, they are assumed by the senior cardinal bishop in attendance. In 2005, the dean himself—Joseph Cardinal Ratzinger—was elected pope, thus impeding him from the stated duties. In 2013, the dean and sub-dean were not in attendance (being over the age limit), and these functions were assumed by Cardinal Giovanni Battista Re.

Since 533, the new pope has also decided on his regnal name. Pope John II was the first to adopt a new papal name; he felt that his original name, Mercurius, was inappropriate, as it was also the name of a Roman god. In most cases, even if such considerations are absent, popes tend to choose papal names different from their baptismal names; the last pope to reign under his baptismal name was Pope Marcellus II (1555). After the newly elected pope accepts his election, the dean asks him about his papal name, saying in Latin: Quo nomine vis vocari? ('By what name do you wish to be called?') After the papal name is chosen, the officials are readmitted to the conclave, and the master of papal liturgical celebrations writes a document recording the acceptance and the new name of the pope.

In the past, when the cardinals voted during a conclave, they sat on canopied thrones symbolizing the cardinals' collective governance of the church during the period of sede vacante.[39] Upon the acceptance by the new pope of his election, all other cardinals in attendance each pulled a cord and lowered the canopies above their respective thrones, signifying an end to the period of collective governance, and only the newly elected pope's canopy remained unlowered.[39] The last time canopied thrones were used was during the 1963 conclave.[102] Beginning with the 1978 August conclave, canopied thrones were no longer used due to the lack of space resulting from the large increase in the number of cardinal electors (two rows of seats needed).

At the end of the conclave, the new pope could give his cardinalitial zucchetto or skull cap to the secretary of the conclave, indicating the secretary would be made cardinal at the next consistory to create cardinals. Prior to the 2013 conclave, this tradition was last followed at the 1958 conclave by the newly elected Pope John XXIII, who bestowed his cardinal's skull cap on Alberto di Jorio and created him a cardinal at the consistory on 15 December of that year. In 2013, the Portuguese section of Vatican Radio reported that at the conclusion of the 2013 conclave, the newly elected Pope Francis bestowed his cardinalitial zucchetto on Archbishop Lorenzo Baldisseri, the secretary of that conclave,[103] and on 22 February 2014 at Pope Francis' first consistory, Baldisseri was formally made a cardinal with the title of Cardinal-Deacon of Sant'Anselmo all'Aventino.[104]

Then, the new pope goes to the Room of Tears, a small red room next to the Sistine Chapel; the room carries the nickname because of the strong emotions experienced by the new pope. The new pope dresses by himself, choosing a set of pontifical robes—consisting of a white cassock, rochet, and red mozzetta—from three sizes provided. He then dons a gold corded pectoral cross, a red and gold embroidered stole, and then the white papal zucchetto on his head. In 2013, Pope Francis dispensed with the red mozzetta, rochet, and gold pectoral cross, wearing only the white cassock and his own pectoral cross when he appeared on the central balcony. He also did not emerge wearing the stole, vesting in it only to impart the Apostolic Blessing, and removing it shortly after.

Next, the protodeacon of the College of Cardinals (the senior cardinal deacon) appears at the loggia of the basilica to proclaim the new pope. He usually proceeds with the following traditional Latin formula (assuming that a cardinal has been elected):[105]

During the announcement for Pope Benedict XVI's election, the protodeacon, Cardinal Jorge Medina, first greeted the crowds with "Dear brothers and sisters" in several different languages before proceeding to the Latin announcement. This was not done when Pope Francis was elected.

In the past, the protodeacon has himself been elected pope. In such an event, the announcement is made by the next senior deacon, who has thus succeeded as protodeacon. The last time the cardinal protodeacon was elected was in 1513, when Giovanni de Medici was elected as Pope Leo X and the next senior cardinal deacon Alessandro Farnese (the future Pope Paul III) made the announcement. After the election of Pope Leo XIII in 1878, Protodeacon Prospero Caterini appeared and started to make the announcement but was physically incapable of completing it, so another made it for him.[lower-alpha 6]

At the end of the conclave of 2013, the newly elected Pope Francis appears for the first time to the crowd in St. Peter's Square

Following the announcement, the senior cardinal deacon retreats, and papal aides unfurl a large, maroon banner that out of practicality often bears the late pope's arms in the centre, draping it onto the railing of the basilica's loggia.[109] During Popes John Paul II’s and Francis' announcement, there was no image of his predecessor's arms (indicating that the previous pope had just died, or was still alive at the time of the conclave), and during Pope Pius XI's first appearance following his election at the 1922 conclave, the banner showed the arms of Pope Pius IX instead of the arms of his immediate predecessor Pope Benedict XV.[110] The new pope then emerges onto the balcony to the adulation of the crowd, while a brass band in the forecourt below plays the Pontifical Anthem. He then imparts the Urbi et Orbi blessing. The Pope may on this occasion choose to give the shorter episcopal blessing as his first Apostolic Blessing instead of the traditional Urbi et Orbi blessing, this happened most recently with Pope Paul VI after his election at the 1963 conclave.[111] Beginning with Pope John Paul II, the last three popes elected including Pope Francis, have chosen to address the crowds first before imparting the Urbi et Orbi blessing. Also, at Pope Francis' first appearance, he led the faithful first in prayers for his predecessor and asked them for prayers for himself before imparting the Urbi et Orbi blessing.

Formerly, the popes were crowned by the triregnum, or triple tiara, at the Papal Coronation. All popes since John Paul I have refused an elaborate coronation, choosing instead to have a simpler papal inauguration ceremony.[112]
