The Second Council of Lyon was the fourteenth ecumenical council of the Catholic Church, convoked on 31 March 1272 and convened in Lyon, France, in 1272–1274. Pope Gregory X presided over the council, called to act on a pledge by Byzantine emperor Michael VIII to reunite the Eastern church with the West. The council was attended by about 300 bishops, sixty abbots and more than a thousand prelates or their procurators, among whom were the representatives of the universities. Due to the great number of attendees, those who had come to Lyon without being specifically summoned were given "leave to depart with the blessing of God" and of the Pope. Among others who attended the council were James I of Aragon, the ambassador of the Emperor Michael VIII Palaiologos with members of the Greek clergy and the ambassadors of Abaqa Khan of the Ilkhanate. Thomas Aquinas had been summoned to the council, but died en route at Frosinone. Bonaventure was present at the first four sessions, but died at Lyon on 15 July.
In addition to Aragon, which James represented in person, representatives of the kings of Germany, England, Scotland, France, the Spains and Sicily  were present, with procurators also representing the kingdoms of Norway, Sweden, Hungary, Bohemia, the "realm of Dacia" and the duchy of Poland. In the procedures to be observed in the council, for the first time the nations appeared as represented elements in an ecclesiastical council, as they had already become represented in the governing of medieval universities. This innovation marks a stepping-stone towards the acknowledgment of coherent ideas of nationhood, which were in the process of creating the European nation-states.
The main topics discussed at the council were the conquest of the Holy Land and the union of the Eastern and Western Churches. The first session took place on 7 May 1274 and was followed by five additional sessions on 18 May, 4 or 7 June, 6 July, 16 July and 17 July. By the end of the council, thirty-one constitutions were promulgated. In the second session, the fathers approved the decree Zelus fidei, which contained no juridical statutes but rather summed up constitutions about the perils of the Holy Land, the means for paying for a proposed crusade, the excommunication of pirates and corsairs and those who protected them or traded with them, a declaration of peace among Christians, a grant of an indulgence for those willing to go on crusade, restoration of communion with the Greeks, and the definition of the order and procedure to be observed in the council. The Greeks conceded on the issue of the Filioque (two words added to the Nicene creed), and union was proclaimed, but the union was later repudiated by Andronicus II, heir to Michael VIII. The council also recognized Rudolf I as Holy Roman Emperor, ending the Interregnum.
Union of the Churches 
Wishing to end the Great Schism that divided the (Eastern) Orthodox Church from the Roman Catholic Church, Gregory X had sent an embassy to Michael VIII Palaeologus, who had reconquered Constantinople, putting an end to the remnants of the Latin Empire in the East, and he asked Latin despots in the East to curb their ambitions. Eastern dignitaries arrived at Lyon on 24 June presenting a letter from the Emperor. On 29 June (the Feast of Peter and Paul, patronal feast of the popes), Gregory celebrated a Mass in St John's Church, where both sides took part. The Greeks read the Nicene Creed, with the Western addition of the Filioque clause sung three times. The council was seemingly a success, but did not provide a lasting solution to the schism; the Emperor was anxious to heal the schism, but the Eastern clergy opposed the decisions of the Council. Patriarch Joseph of Constantinople abdicated, and was replaced by John Bekkos, a convert to the cause of union. In spite of a sustained campaign by Bekkos to defend the union intellectually, and vigorous and brutal repression of opponents by Michael, the vast majority of Byzantine Christians remained implacably opposed to union with the Latin "heretics". Michael's death in December 1282 put an end to the union of Lyons. His son and successor Andronicus II repudiated the union, and Bekkos was forced to abdicate, being eventually exiled and imprisoned until his death in 1297. He is to this day reviled by many in the Eastern Church as a traitor to Orthodoxy.
Plans for a Crusade 
The council drew up plans for a crusade to recover the Holy Land, which was to be financed by a tithe imposed for six years on all the benefices of Christendom. The plans were approved but nothing concrete was done. James I of Aragon wished to organize the expedition at once, but this was opposed by the Knights Templar.
Ambassadors of the Khan of the Tatars negotiated with the Pope, who asked them to leave Christians in peace during their war against Islam. The Mongol leader Abaqa Khan sent a delegation of 13-16 Mongols to the Council, which created a great stir, particularly when their leader underwent a public baptism. Among the embassy were David of Ashby, and the clerk Rychaldus. According to one chronicler, "The Mongols came, not because of the Faith, but to conclude an alliance with the Christians".
Abaqa's Latin secretary Rychaldus delivered a report to the Council, which outlined previous European-Ilkhanid relations under Abaqa's father, Hulagu, where after welcoming the Christian ambassadors to his court, Hulagu had agreed to exempt Latin Christians from taxes and charges, in exchange for their prayers for the Qaghan. According to Richardus, Hulagu had also prohibited the molestation of Frank establishments, and had committed to return Jerusalem to the Franks. Richardus told the assembly that even after Hulagu's death, Abaqa was still determined to drive the Mamluks from Syria.
At the Council, Pope Gregory promulgated a new Crusade to start in 1278 in liaison with the Mongols. The Pope put in place a vast program to launch the Crusade, which was written down in his “Constitutions for the zeal of the faith”. This text puts forward four main decisions to accomplish the Crusade: the imposition of a new tax during three years, the interdiction of any kind of trade with the Saracens, the supply of ships by the Italian maritime Republics, and the alliance of the West with Byzantium and the Il-Khan Abagha. However, despite papal plans, there was little support from European monarchs, who at this point were more likely to give lip service to the idea of a Crusade than to commit actual troops. The Pope's death in 1276 put an end to any such plans, and the money that had been gathered was instead distributed in Italy.
Other topics debated 
The council dealt with the reform of the Church, regarding which Gregory had sent out inquiries. Several bishops and abbots were deposed for unworthiness, and some mendicant orders were suppressed. On the other hand, the two new orders of Dominicans and Franciscans were approved.
There had been several lengthy vacancies of the Holy See, most recently the sede vacante that had lasted from the death of Clement IV, 29 November 1268, until Gregory's election, 1 September 1271. The council decided that in future the cardinals should not leave the conclave until they had elected a pope. This decision was suspended in 1276 by Pope Adrian V, and then revoked by Pope John XXI. It has since been re-established, and is the basis of present legislation on papal elections.
Finally, the council dealt with the Imperial throne, which James I of Aragon claimed. His claim was disallowed by the Pope, and Rudolph I was proclaimed King of the Romans and future emperor on 6 June.
