Pope Martin V convoked the Council of Basel in 1431. It became the Council of Ferrara in 1438 and the Council of Florence in 1439.

The Seventeenth Ecumenical Council of the Roman Catholic Church was convoked as the Council of Basel (Basle in the once-preferred English spelling) by Pope Martin V shortly before his death in February 1431 and took place in the context of the Hussite wars in Bohemia and the rise of the Ottoman Empire. At stake was the greater conflict between the Conciliar movement and the principle of papal supremacy.

The Council entered a second phase after rump council reconvened in Lausanne before dissolving itself in 1449.

The initial location at Basel reflected the desire among parties seeking reform to meet outside the territories of the Papacy, the Holy Roman Empire or the kings of Aragon and France, whose influences the council hoped to avoid. Ambrogio Traversari attended the Council of Basel as legate of Pope Eugene IV.

Under pressure for ecclesiastical reform Pope Martin V sanctioned a decree of the Council of Constance (9 October 1417) obliging the papacy to summon general councils periodically. At the expiration of the first term fixed by this decree, Pope Martin V complied by calling a council at Pavia. Due to an epidemic the location transferred almost at once to Siena (see Council of Siena) and disbanded —owing to circumstances still imperfectly known— just as it had begun to discuss the subject of reform (1424). The next council fell due at the expiration of seven years in 1431; Martin V duly convoked it for this date to the town of Basel, and selected to preside over it the cardinal Julian Cesarini, a well-respected prelate. Martin himself, however, died before the opening of the synod.

The Council was seated on December 14, 1431, at a period when the conciliar movement was strong and the authority of the papacy weak. The Council at Basel opened with only a few bishops and abbots attending, but it grew rapidly and to make its numbers greater gave the lower orders a majority over the bishops. It adopted an anti-papal attitude, proclaimed the superiority of the Council over the Pope and prescribed an oath to be taken by every Pope on his election. On December 18 Martin's successor, Pope Eugene IV, tried to dissolve it and open a new council on Italian soil at Bologna, but was overruled.

Sigismund, King of Hungary and titular King of Bohemia, had been defeated at the Battle of Domažlice in the fifth crusade against the Hussites in August 1431, and under his sponsorship the Council negotiated a peace with Calixtine faction of the Hussites in January, 1433. Pope Eugene acknowledged the council in May and crowned Sigismund Holy Roman Emperor on May 31, 1433. The divided Hussites were defeated in May 1434. In June 1434 the pope had to flee a revolt in Rome and began a ten-year exile in Florence.

When the Council was moved from Basel to Ferrara in 1438, some remained at Basel, claiming to be the Council. They elected Amadeus VIII, Duke of Savoy, as Antipope. Driven out of Basel in 1448, they moved to Lausanne, where Felix V, the Pope they had elected and the only claimant to the papal throne who ever took the oath that they had prescribed, resigned. Next year, they decreed the closure of what for them was still the Council of Basel.[1]

The new council was transferred to Ottoman Turks. Some perhaps feeling political pressure from the Byzantine Emperor, accepted the decrees of the Council. Others did so by sincere conviction, such as Isidore of Kiev, who suffered greatly for it. Only Bishop Mark of Ephesus, however, refused to accept the union and became the leader of opposition back home. The Russians, upon learning of the union, angrily rejected it and ousted any prelate who was even remotely sympathetic to it. Despite the religious union, Western military assistance to Byzantium was meager and Constantinople fell to the Ottomans in May of 1453. The Council declared the Basel group heretics and excommunicated them; and the superiority of the Pope over the Councils was affirmed in the bull Etsi non dubitemus of 20 April 1441.[1]

Composition of the council

The theology, masters and representatives of chapters, monks and clerks of inferior orders constantly outnumbered the prelates in it, and the influence of the superior clergy had less weight because, instead of being separated into "nations", as at Constance, the fathers divided themselves according to their tastes or aptitudes into four large committees or "deputations" (deputationes). One was concerned with questions of faith (fidei), another with negotiations for peace (pacis), the third with reform (reformatorii), and the fourth with what they called "common concerns" (pro communibus). Every decision made by three of these "deputations" — and in each of them the lower clergy formed the majority — received ratification for the sake of form in general congregation, and if necessary led to decrees promulgated in session. For this reason papal critics termed the council "an assembly of copyists" or even "a set of grooms and scullions". However, some prelates, although absent, were represented by their proxies.

Nicholas of Cusa was a member of the delegation sent to Constantinople with the pope's approval to bring back the Byzantine emperor and his representatives to the Council of Florence of 1439. At the time of the council's conclusion in 1439, Cusa was thirty-eight years old, and thus, compared to the other clergy at the council, a fairly young man, though one of the more accomplished in terms of the body of his complete works.

Attempted dissolution

From Italy, France and Germany the fathers came late to Basel. Cesarini devoted all his energies to the war against the Hussites, until the disaster of Taus forced him to evacuate Bohemia in haste. Pope Eugene IV, Martin V's successor, lost hope that the council could be useful owing to the progress of heresy, the reported troubles in Germany, the war which had lately broken out between the dukes of Austria and Burgundy, and finally, the small number of fathers who had responded to the summons of Martin V. This opinion, added to his desire to preside over the council in person, induced him to recall the fathers from Germany, as his poor health made it difficult for him to go. He commanded the council to disperse, and appointed Bologna as their meeting-place in eighteen months' time, with the intention of making the session of the council coincide with some conferences with representatives of the Orthodox Church of the Greek East, scheduled to be held there with a view to ecumenical union (18 December 1431).

This order led to an outcry among the fathers and incurred the deep disapproval of the legate Cesarini. They argued that the Hussites would think the Church afraid to face them, and that the laity would accuse the clergy of shirking reform, both with disastrous effects. The pope explained his reasons and yielded certain points, but the fathers were intransigent. Considerable powers had been decreed to Church councils by the Council of Constance, which amid the troubles of the Western Schism had proclaimed the superiority, in certain cases, of the council over the pope, and the fathers at Basel insisted upon their right of remaining assembled. They held sessions, promulgated decrees, interfered in the government of the papal countship of Venaissin, treated with the Hussites, and, as representatives of the universal Church, presumed to impose laws upon the sovereign pontiff himself.

Eugene IV resolved to resist the Council's claim of supremacy, but he did not dare openly to repudiate the conciliar doctrine considered by many to be the actual foundation of the authority of the popes before the schism. He soon realized the impossibility of treating the fathers of Basel as ordinary rebels, and tried a compromise; but as time went on, the fathers became more and more intractable, and between him and them gradually arose an impassable barrier.

Abandoned by a number of his cardinals, condemned by most of the powers, deprived of his dominions by condottieri who shamelessly invoked the authority of the council, the pope made concession after concession, and ended on 15 December 1433 with a pitiable surrender of all the points at issue in a Papal bull, the terms of which were dictated by the fathers of Basel, that is, by declaring his bull of dissolution null and void, and recognising that the synod as legitimately assembled throughout. However, Eugene IV did not ratify all the decrees coming from Basel, nor make a definite submission to the supremacy of the council. He declined to express any forced pronouncement on this subject, and his enforced silence concealed the secret design of safeguarding the principle of sovereignty.

Sketches by Pisanello of the Byzantine delegation at the Council

The fathers, filled with suspicion, would allow only the legates of the pope to preside over them on condition of their recognizing the superiority of the council. The legates did submit to this humiliating formality but in their own names, it was asserted only after the fact, thus reserving the final judgment of the Holy See. Furthermore, the difficulties of all kinds against which Eugene had to contend, such as the insurrection at Rome, which forced him to escape by means of the Tiber, lying in the bottom of a boat, left him at first little chance of resisting the enterprises of the council.

Issues of reform

Emboldened by their success, the fathers approached the subject of reform, their principal object being to further curtail the power and resources of the papacy. They took decisions on the disciplinary measures which regulated the elections, on the celebration of divine service, on the periodical holding of diocesan synods and provincial councils, which were usual topics in Catholic councils. They also made decrees aimed at some of the assumed rights by which the popes had extended their power and improved their finances at the expense of the local churches. Thus the council abolished annates, greatly limited the abuse of "reservation" of the patronage of benefices by the pope, and completely abolished the right claimed by the pope of "next presentation" to benefices not yet vacant (known as gratiae expectativae). Other conciliar decrees severely limited the jurisdiction of the court of Rome, and even made rules for the election of popes and the constitution of the Sacred College. The fathers continued to devote themselves to the subjugation of the Hussites, and they also intervened, in rivalry with the pope, in the negotiations between France and England which led to the treaty of Arras, concluded by Charles VII of France with the duke of Burgundy. Also, circumcision was deemed to be a mortal sin. Finally, they investigated and judged numbers of private cases — lawsuits between prelates, members of religious orders and holders of benefices—thus themselves committing one of the serious abuses for which they had criticized the court of Rome.

Papal Supremacy

The Council clarified the Latin dogma of papal supremacy:

"We likewise define that the holy Apostolic See, and the Roman Pontiff, hold the primacy throughout the entire world; and that the Roman Pontiff himself is the successor of blessed Peter, the chief of the Apostles, and the true vicar of Christ, and that he is the head of the entire Church, and the father and teacher of all Christians; and that full power was given to him in blessed Peter by our Lord Jesus Christ, to feed, rule, and govern the universal Church."[2]

Eugene IV's eastern strategy

A figure in Benozzo Gozzoli's 1459 Journey of the Magi is assumed to portrait John VIII Palaiologos.

Eugene IV, however much he may have wished to keep on good terms with the fathers of Basel, found himself neither able nor willing to accept or observe all their decrees. The question of the union with the Greek church, especially, gave rise to a misunderstanding between them which soon led to a rupture. The Byzantine emperor John VIII Palaiologos, pressed hard by the Ottoman Turks, was keen to ally himself with the Catholics. He consented to come with the principal representatives of the Byzantine Church to some place in the West where the union could be concluded in the presence of the pope and of the Latin council. There arose a double negotiation between him and Eugene IV on the one hand and the fathers of Basel on the other. The council wished to fix the meeting-place at a place remote from the influence of the pope, and they persisted in suggesting Basel, Avignon or Savoy. On the other hand, the Byzantines wanted a coastal location in Italy for their ease of access by ship.

Council transferred to Ferrara and attempted re-union with the Orthodox Churches

John Argyropoulos was a Greek Byzantine diplomat who was present at the Council of Florence in 1439.[3]

As a result of negotiations with the East, John VIII Palaiologos accepted the pope's offer, who, by a bill dated 18 September 1437, again pronounced the dissolution of the council of Basel, and summoned the fathers to Ferrara.

The first public session at Ferrara began on 10 January 1438. Its first act was to declare the Council of Basel transferred to Ferrara and to nullify all further proceedings at Basel. In the second public session (15 February 1438), Pope Eugene IV excommunicated all who continued to assemble at Basel.

In early April 1438, the Greek contingent arrived at Ferrara over 700 strong. On 9 April 1438 the first solemn session at Ferrara began with the Eastern Roman Emperor, the Patriarch of Constantinople and representatives of the Patriarchal Sees of Antioch, Alexandria and Jerusalem in attendance and Pope Eugene IV presiding. The early sessions lasted until 17 July 1438 with each theological issue of the Great Schism (1054) hotly debated, including the Processions of the Holy Spirit, Filioque clause in the Nicene Creed, Purgatory and Papal Primacy. Resuming proceedings on 8 October 1438, the council focused exclusively on the Filioque matter. Even as it became clear the Greek Church would never consent to the Filioque clause, the Emperor continued to press for a reconciliation.

Council transferred to Florence and the near East-West union

With finances running thin and on the pretext that the plague was spreading in the area, both the Latins and the Greeks agreed to transfer the council to Florence.[4] Continuing at Florence in January 1439, the Council made steady progress on a compromise formula, "ex filio." In the following months, agreement was reached on the Western doctrine of Purgatory and a return to the pre-schism prerogatives of the Papacy. On 6 July 1439 an agreement (Laetentur caeli) was signed by Patriarch Joseph II of Constantinople and all the Eastern bishops but one, Mark of Ephesus, who held that Rome continued in both heresy and schism. However, after Patriarch Joseph died two days later, the Greek monks therefore were able to assert that ratification by the Eastern Church could be achieved only by the agreement of the whole Church. (The agreement of a Patriarch is not binding over the whole Orthodox Church; the Patriarchs are just considered first among equals among the local bishops of the patriarchy, and do not hold any power outside their bishopric - they cannot even perform sacraments outside their bishopric without blessing of the local bishop.) Upon their return, the Eastern bishops found their agreement with the West broadly rejected by the monks, the populace and by civil authorities (with the notable exception of the Emperors of the East who remained committed to union until the fall of the Byzantine Empire to the Turkish Ottoman Empire two decades later). The union signed at Florence, down to the present, has never been accepted by the Eastern Churches.

Copts and Ethiopians

The multinational character of the Council inspired Benozzo Gozzoli's 1459 Journey of the Magi, featuring a black figure in the attendance.[5]

The Council soon became even more international. The signature of this agreement for the union of the Latins and the Greeks encouraged Pope Eugenius to announce the good news to the Coptic Christians, and invite them to send a delegation to Florence. He wrote a letter on 7 July 1439, and to deliver it, sent Alberto da Sarteano as an apostolic delegate. On 26 August 1441, Sarteano returned with four Ethiopians from Emperor Zara Yaqob and Copts.[6] According to a contemporary observer "They were black men and dry and very awkward in their bearing (...) really, to see them they appeared to be very weak".[7] At that time, Rome had delegates from a multitude of nations, from Armenia to Russia, Greece and various parts of north and east Africa.[8]

"Deposition of Eugene IV" and schism at Basel

During this time the council of Basel, though nullified at Ferrara and abandoned by Cesarini and most of its members, persisted nonetheless, under the presidency of Cardinal Aleman. Affirming its ecumenical character on 24 January 1438, it suspended Eugene IV. The council went on (in spite of the intervention of most of the powers) to pronounce Eugene IV deposed (25 June 1439), giving rise to a new schism by electing (4 November 1439) duke Amadeus VIII of Savoy, as (anti)pope, who took the name of Felix V.

Effects of the schism

This schism lasted fully ten years, although the antipope found few adherents outside of his own hereditary states, those of Alfonso V of Aragon, of the Swiss confederation and of certain universities. Germany remained neutral; Charles VII of France confined himself to securing to his kingdom (by the Pragmatic Sanction of Bourges, which became law on 13 July 1438) the benefit of a great number of the reforms decreed at Basel; England and Italy remained faithful to Eugene IV. Finally, in 1447, Frederick III, Holy Roman Emperor, after negotiations with Eugene, commanded the burgomaster of Basel not to allow the presence of the council any longer in the imperial city.

Schism reconciled at Lausanne

In June 1448 the rump of the council migrated to Lausanne. The antipope, at the insistence of France, ended by abdicating (7 April 1449). Eugene IV died on 23 February 1447, and the council at Lausanne, to save appearances, gave their support to his successor, Pope Nicholas V, who had already been governing the Church for two years. Trustworthy evidence, they said, proved to them that this pontiff accepted the dogma of the superiority of the council as defined at Constance and at Basel.


The struggle for East-West union at Ferrara and Florence, while promising, never bore fruit. While progress toward union in the East continued to be made in the following decades, all hopes for a proximate reconciliation were dashed with the fall of Constantinople in 1453.

Perhaps the council's most important historical legacy was the lectures on Greek classical literature given in Florence by many of the delegates from Constantinople, including the renowned Neoplatonist Gemistus Pletho. These greatly helped the progress of Renaissance humanism.[9]
