James I of Aragon in the context of "Iberian Crusades"

The Kingdom of Mallorca was an insular realm off the east coast of modern day Spain, which included the islands of Mallorca, Menorca, Ibiza and Formentera. The islands were conquered from the Almohad Caliphate by James I of Aragon, and were integrated in the Crown of Aragon. The king became known as James the Conqueror due to the Conquest of Mallorca.

When James I died in 1276, he divided his territories between his three surviving sons. Peter, the eldest, succeeded his father in the mainland as Peter III of Aragon or Peter the Great. The Kingdom of Mallorca passed to the younger son James, who reigned as James II of Mallorca.

The 1412 Compromise of Caspe (Compromiso de Caspe in Spanish, Compromís de Casp in Catalan) was an act and resolution of parliamentary representatives of the constituent realms of the Crown of Aragon (the Kingdom of Aragon, Kingdom of Valencia, and Principality of Catalonia), meeting in Caspe, to resolve the interregnum following the death of King Martin of Aragon in 1410 without a legitimate heir. Succession through the male line, as ordained in the will of James I of Aragon should have gone to James II, Count of Urgell, however multiple others claimed the throne, which led to the "conclave" and compromise.

Montpellier (UK: /mɒntˈpɛlieɪ/; US: /ˌmoʊnpɛlˈjeɪ/) is a city in southern France near the Mediterranean Sea. One of the largest urban centres in the region of Occitania, Montpellier is the prefecture of the department of Hérault. At the 2020 census, 299,096 people lived in the city proper, while its metropolitan area had a population of 813,272. The inhabitants are called Montpelliérains.

In the Middle Ages, Montpellier was an important city of the Crown of Aragon (and was the birthplace of James I), and then of Majorca, before its sale to France in 1349. Established in 1220, the University of Montpellier is one of the oldest universities in the world and has the oldest medical school still in operation, with notable alumni such as Petrarch, Nostradamus and François Rabelais. Above the medieval city, the ancient citadel of Montpellier is a stronghold built in the seventeenth century by Louis XIII.

The conquest of the island of Majorca on behalf of the Roman Catholic kingdoms was carried out by King James I of Aragon between 1229 and 1231. The pact to carry out the invasion, concluded between James I and the ecclesiastical and secular leaders, was ratified in Tarragona on 28 August 1229. It was open and promised conditions of parity for all who wished to participate.

James I reached an agreement regarding the arrival of the Catholic troops with a local chief in the Port de Pollença, but the strong mistral winds forced the king to divert to the southern part of the island. He landed at midnight on 10 September 1229, on the coast where there is now the tourist resort of Santa Ponsa, the population centre of the Calviá municipality. Although the city of Madina Mayurqa (now Palma de Mallorca) fell within the first year of the conquest, the Muslim resistance in the mountains lasted for three years.

James II (Catalan: Jaume) (31 May 1243 – 29 May 1311) was King of Majorca and Lord of Montpellier from 1276 until his death. He was the second son of James I of Aragon and his wife, Violant, daughter of Andrew II of Hungary. In 1279, by the Treaty of Perpignan, he became a vassal of the Crown of Aragon.

The conquest of Valencia by the Catalan and Aragonese troops of King James I of Aragon took place on 9 October 1238.

Furs of Valencia (Valencian: Furs de València, IPA: [ˈfuɾz ðe vaˈlensi.a]) were the laws of the Kingdom of Valencia during most of the Middle Ages and early modern Europe. The laws were a series of charters which, altogether, worked similarly as a modern constitution does now. Thus, they defined the position of and checks and balances between the royal house, the nobility, the Catholic ecclesiastics and the judiciary. The first codifications are based in the Usages of Barcelona, Costums of Lleida, and the Furs of Aragon.

They were promulgated by the first King of Valencia, James I of Aragon in 1261 at the newly created Valencian Parliament; he then subjected the title of King of Valencia to an oath of office before the Parliament, sworn on the Furs.

The Second Council of Lyon was the fourteenth ecumenical council of the Roman Catholic Church, convoked on 31 March 1272 and convened in Lyon, Kingdom of Arles (in modern France), in 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, 60 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 Fossanova Abbey. Bonaventure was present at the first four sessions but died at Lyon on 15 July 1274. As at the First Council of Lyon, Thomas Cantilupe was an English attendee and a papal chaplain.

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, Poland, and the "realm of Dacia". 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.
