Second Council of LyonThe First Council of Lyon, the Thirteenth Ecumenical Council, took place in 1245. 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.
Eighth CrusadeThe Eighth Crusade was the second Crusade launched by Louis IX of France, this one against the Hafsid dynasty in Tunisia in 1270. It is also known as the Crusade of Louis IX Against Tunis or the Second Crusade of Louis. The Crusade did not see any significant fighting as King Louis died of dysentery shortly after arriving on the shores of Tunisia. The Treaty of Tunis was negotiated between the Crusaders and the Hafsids. No changes in territory occurred, though there were commercial and some political rights granted to the Christians.
ArghunArghun Khan (Mongolian Cyrillic: Аргун; Traditional Mongolian: ; c. 1258 – 10 March 1291) was the fourth ruler of the Mongol empire's Ilkhanate, from 1284 to 1291. He was the son of Abaqa Khan, and like his father, was a devout Buddhist (although pro-Christian). He was known for sending several embassies to Europe in an unsuccessful attempt to form a Franco-Mongol alliance against the Muslim Mamluks in the Holy Land. It was also Arghun who requested a new bride from his great-uncle Kublai Khan.
Islamic Golden AgeThe Islamic Golden Age was a period of scientific, economic and cultural flourishing in the history of Islam, traditionally dated from the 8th century to the 13th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom, which saw scholars from all over the Muslim world flock to Baghdad, the world's largest city by then, to translate the known world's classical knowledge into Arabic and Persian.
Seventh CrusadeThe Seventh Crusade (1248–1254) was the first of the two Crusades led by Louis IX of France. Also known as the Crusade of Louis IX to the Holy Land, it aimed to reclaim the Holy Land by attacking Egypt, the main seat of Muslim power in the Near East. The Crusade was conducted in response to setbacks in the Kingdom of Jerusalem, beginning with the loss of the Holy City in 1244, and was preached by Innocent IV in conjunction with a crusade against emperor Frederick II, Baltic rebellions and Mongol incursions.
TekuderAhmed Tekuder (Mongolian: Tegülder, meaning “perfect”; تکودر) (c. 1246 10 August 1284), also known as Sultan Ahmad (reigned 1282–1284), was the sultan of the Persian-based Ilkhanate, son of Hulegu and brother of Abaqa. He was eventually succeeded by his nephew Arghun Khan. Tekuder was born c. 1246 in Mongolia to Hulagu and Qutui Khatun from Khongirad tribe as his seventh son. His birth date is not mentioned elsewhere but according to sources he died aged 37, therefore his birth year must have been around 1246 or 1247.
NaimansThe Naiman (Mongolian: Найман, Naiman, "eight"; ; Kazakh: Найман, Naiman; Uzbek: Nayman) were a medieval tribe originating in the territory of modern Western Mongolia (possibly during the time of the Uyghur Khaganate), and are one of the tribes of modern Mongols and in the middle juz of the Kazakh nation. In The Secret History of the Mongols, the Naiman subtribe the "Güchügüd" are mentioned. According to Russian Turkologist Nikolai Aristov's view, the Naiman Khanate's western border reached the Irtysh River and its eastern border reached the Mongolian Tamir River.
Battle of Ain JalutThe Battle of Ain Jalut (معركة عين جالوت), also spelled Ayn Jalut, was fought between the Bahri Mamluks of Egypt and the Mongol Empire on 3 September 1260 (25 Ramadan 658 AH) near the spring of Ain Jalut in southeastern Galilee in the Jezreel Valley. Continuing the westward expansion of the Mongol Empire, the armies of Hulagu Khan captured and sacked Baghdad in 1258, along with the Ayyubid capital of Damascus sometime later.
