Consequences
In the intense partisanship that was characteristic of the Middle Ages, the schism engendered a fanatical hatred noted by
Johan Huizinga:
Sustained by such national and factional rivalries, the schism continued after the deaths of both Urban VI in 1389 and Clement VII in 1394.
Boniface IX was crowned in Rome in 1389, and
Benedict XIII, who was elected against the wishes of Charles VI of France, reigned in Avignon from 1394. When Pope Boniface died in 1404, the eight cardinals of the Roman conclave offered to refrain from electing a new pope if Benedict would resign; but when Benedict's legates refused on his behalf, the Roman party then proceeded to elect Pope
Innocent VII. Discussions continued instead with Innocent, but quickly stalled and by February 1405, and Benedict's envoys had returned to Avignon. Benedict quickly excommunicated Innocent and with an army started marching towards Rome, in May 1405. He occupied Genoa for a year and awaited French military support, which never came. Innocent died 6 November 1406, and the Roman cardinals elected Angelo Correr as Gregory XII.
The suggestion for a
church council to resolve the Schism, first made in 1378, was not adopted initially, because
canon law
Canon law (from , , a 'straight measuring rod, ruler') is a set of ordinances and regulations made by ecclesiastical jurisdiction, ecclesiastical authority (church leadership) for the government of a Christian organization or church and its membe ...
required that a pope call a council. Eventually theologians like
Pierre d'Ailly and Jean Gerson, adopted arguments that permitted the Church to call a council to resolve this issue, while
Francesco Zabarella argued that a council could only be convoked by an emperor.
Three popes
Benedict and Gregory agreed to abdicate their respective papacies in December 1406. However, Benedict stated that he wanted to negotiate a solution first. Gregory sent an ambassador to the St. Victor abbey in Marseille, where Benedict was staying. On the other hand, Gregory preferred Savona, and Benedict concurred. They balked at the last moment, and both groups of cardinals abandoned their preferred leaders. The
Council of Pisa met in 1409 under the auspices of the cardinals to try solving the dispute. At the fifteenth session, on 5 June 1409, the Council of Pisa attempted to depose both the Roman pope and Avignon antipope as schismatical, heretical, perjured and scandalous, but proceeded to inflame the problem even further by electing Peter Philargi, the cardinal archbishop of Milan, as
Alexander V. He reigned briefly in Pisa from June 26, 1409, to his death in 1410, when he was succeeded by Baldassare Cossa as

, giving it greater legitimacy. On 6 April 1415, the council issued ''
Haec sancta'', stating that the council is the Church's highest governing body and has the authority to remove popes.
''Haec sancta'' is today considered invalid by the Catholic Church, on the basis that Gregory XII was the legitimate pope at the time and the decree was passed by the council in a session before his confirmation; further, since it was not used to remove him, it was not actually used to remove the pope.
The council, advised by the theologian
Jean Gerson, secured the resignation of Gregory XII and the detention and removal of John XXIII. The Avignon antipope
Benedict XIII, who refused to step down, was
excommunicated on 27 July 1417, having lost all his supporters in the process. The Council elected
Pope Martin V
Pope Martin V (; ; January/February 1369 – 20 February 1431), born Oddone Colonna, was the head of the Catholic Church and ruler of the Papal States from 11 November 1417 to his death in February 1431. His election effectively ended the We ...
in 1417, essentially ending the schism.
Benedict XIII, recognized by
King Martin of Aragon in 1397, chose to ignore pleas for his resignation. Benedict died 23 May 1423: to succeed him three cardinals elected Gil Sanchez Munoz y Carbon as
Clement VIII. Clement VIII resigned in 1429 and recognized Martin V.
Aftermath
Conciliarism gained impetus due to the Schism. This new reformist movement held that a general council is superior to the pope on the strength of its capability to resolve ecclesiastical issues. Theorists such as
Jean Gerson explained that the priests and the church itself are the sources of the papal power and, thus, the church should be able to correct, punish, and, if necessary, depose a pope.
On 18 January 1460,
Pope Pius II issued the bull which forbade any attempt to appeal papal judgements by general councils.
There was also a marked decline in discipline within the church. Scholars note that the Western Schism effectively eroded the church's authority and its capacity to proclaim the gospel. This dissension and loss of unity ultimately culminated in the
Protestant Reformation

of the 16th century.
Official list of popes

For the next five centuries, the Catholic Church recognized the Roman popes as the legitimate line from 1378 to 1409, followed by the Pisan popes from 1409 to 1415. All Avignon popes after 1378 are considered to be antipopes. This recognition is reflected in the numbering of popes
Alexander VI
Pope Alexander VI (, , ; born Roderic Llançol i de Borja; epithet: ''Valentinus'' ("The Kingdom of Valencia, Valencian"); – 18 August 1503) was head of the Catholic Church and ruler of the Papal States from 11 August 1492 until his death ...
,
VII, and
VIII, who numbered themselves consecutively after their Pisan namesake Alexander V.
The recognition of the Pisan popes made the continued legitimacy of the Roman pope Gregory XII doubtful for 1409–1415. The for 1860 listed the Pisan popes as true popes from 1409 to 1415, but it acknowledged that Gregory XII's reign ended in either 1409 or 1415.
The Western Schism was, in practice, reinterpreted in 1958 when
Angelo Giuseppe Roncalli chose to reuse the ordinal XXIII upon his election as Pope John XXIII, citing "twenty-two
icJohns of indisputable legitimacy".
(There had actually been twenty undisputed Johns due to
antipopes and numbering errors.) Although Roncalli's declaration of assuming the name specified that his decision was made "apart from disputes about legitimacy", this passage was subsequently excised from the version appearing in the , and the Pisan popes Alexander V and John XXIII have since been classified as antipopes by the Roman Curia. The reinterpretation is reflected in modern editions of the , which extend Gregory XII's reign to 1415. The line of Roman popes is now retroactively recognized by the Catholic Church as the sole legitimate line during the Western Schism. However, Popes Alexander VI through VIII have not been renumbered, leaving a gap in the numbering sequence.
According to John F. Broderick (1987):
