Sixth CrusadeThe Sixth Crusade (1228–1229), also known as the Crusade of Frederick II, was a military expedition to recapture Jerusalem and the rest of the Holy Land. It began seven years after the failure of the Fifth Crusade and involved very little actual fighting. The diplomatic maneuvering of the Holy Roman Emperor and King of Sicily, Frederick II, resulted in the Kingdom of Jerusalem regaining some control over Jerusalem for much of the ensuing fifteen years as well as over other areas of the Holy Land.
Religious warA religious war or a war of religion, sometimes also known as a holy war (sanctum bellum), is a war which is primarily caused or justified by differences in religion and beliefs. In the modern period, there are frequent debates over the extent to which religious, economic, ethnic or other aspects of a conflict are predominant in a given war. The degree to which a war may be considered religious depends on many underlying questions, such as the definition of religion, the definition of 'religious war' (taking religious traditions on violence such as 'holy war' into account), and the applicability of religion to war as opposed to other possible factors.
Möngke KhanMöngke (ˈmɒŋkeɪ ; 11 January 1209 – 11 August 1259) was the fourth khagan of the Mongol Empire, ruling from 1 July 1251, to 11 August 1259. He was the first Khagan from the Toluid line, and made significant reforms to improve the administration of the Empire during his reign. Under Möngke, the Mongols conquered Iraq and Syria as well as the kingdom of Dali (modern-day Yunnan). According to William of Rubruck, Möngke Khan was a man of medium height. Möngke was born on 11 January 1209, as the eldest son of Genghis Khan's teenaged son Tolui and Sorghaghtani Beki.
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.
Albigensian CrusadeThe Albigensian Crusade or the Cathar Crusade (Croisade des albigeois; 1209–1229) was a military and ideological campaign initiated by Pope Innocent III to eliminate Catharism in Languedoc, what is now southern France. The Crusade was prosecuted primarily by the French crown and promptly took on a political aspect. It resulted in the significant reduction of practicing Cathars and a realignment of the County of Toulouse with the French crown. The distinct regional culture of Languedoc was also diminished.
ShirkuhAsad ad-Dīn Shīrkūh bin Shādhī (ئەسەد الدین شێرکۆ; أسد الدين شيركوه بن شاذي), also known as Shirkuh, or Şêrko (meaning "lion of the mountains" in Kurdish) (died 22 February 1169) was a Kurdish military commander, and uncle of Saladin. His military and diplomatic efforts in Egypt were a key factor in establishing the Ayyubid dynasty in that country. Shirkuh is a Kurdish name which literally means "the lion (of the) mountain". Shirkuh is also the name of several villages in modern-day Iran.
Kingdom of JerusalemThe Kingdom of Jerusalem, also known as the Latin Kingdom of Jerusalem, was a Crusader state that was established in the Levant immediately after the First Crusade. It lasted for almost two hundred years, from the accession of Godfrey of Bouillon in 1099 until the siege of Acre in 1291. Its history is divided into two periods with a brief interruption in its existence, beginning with its collapse after the siege of Jerusalem in 1187 and its restoration after the Third Crusade in 1192.
Knights TemplarThe Poor Fellow-Soldiers of Christ and of the Temple of Solomon (Pauperes commilitones Christi Templique Salomonici), also known as the Order of Solomon's Temple, the Knights Templar, or simply the Templars, was a military order of the Catholic faith, and one of the wealthiest and most popular military orders in Western Christianity. They were founded circa 1119, headquartered on the Temple Mount in Jerusalem, and existed for nearly two centuries during the Middle Ages.
Third CrusadeThe Third Crusade (1189–1192) was an attempt led by three European monarchs of Western Christianity (Philip II of France, Richard I of England and Frederick I, Holy Roman Emperor) to reconquer the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187. For this reason, the Third Crusade is also known as the Kings' Crusade. It was partially successful, recapturing the important cities of Acre and Jaffa, and reversing most of Saladin's conquests, but it failed to recapture Jerusalem, which was the major aim of the Crusade and its religious focus.
Principality of AntiochThe Principality of Antioch was one of the crusader states created during the First Crusade which included parts of modern-day Turkey and Syria. The principality was much smaller than the County of Edessa or the Kingdom of Jerusalem. It extended around the northeastern edge of the Mediterranean, bordering the County of Tripoli to the south, Edessa to the east, and the Byzantine Empire or the Kingdom of Armenia to the northwest, depending on the date.
