Pope Innocent IV, born Sinibaldo Fieschi, was head of the Catholic Church and ruler of the Papal States from 25 June 1243 to his death in 1254.
Year 1254 (MCCLIV) was a common year starting on Thursday of the Julian calendar.
The 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.
The 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 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. The Crusaders withdrew back to Europe soon after.
John of Brienne, also known as John I, was King of Jerusalem from 1210 to 1225 and Latin Emperor of Constantinople from 1229 to 1237. He was the youngest son of Erard II of Brienne, a wealthy nobleman in Champagne. John, originally destined for an ecclesiastical career, became a knight and owned small estates in Champagne around 1200. After the death of his brother, Walter III, he ruled the County of Brienne on behalf of his minor nephew Walter IV.
The Fifth Crusade was a campaign in a series of Crusades by Western Europeans to reacquire Jerusalem and the rest of the Holy Land by first conquering Egypt, ruled by the powerful Ayyubid sultanate, led by al-Adil, brother of Saladin.
The 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. After initial success, the crusade ended in defeat, with most of the army – including the king – captured by the Muslims.
Bohemond IV of Antioch, also known as Bohemond the One-Eyed, was Count of Tripoli from 1187 to 1233, and Prince of Antioch from 1201 to 1216 and from 1219 to 1233. He was the younger son of Bohemond III of Antioch. The dying Raymond III of Tripoli offered his county to Bohemond's elder brother, Raymond, but their father sent Bohemond to Tripoli in late 1187. Saladin, the Ayyubid sultan of Egypt and Syria, conquered the county, save for the capital and two fortresses, in summer 1188.
John of Ibelin, count of Jaffa and Ascalon, was a noted jurist and the author of the longest legal treatise from the Kingdom of Jerusalem. He was the son of Philip of Ibelin, bailli of the Kingdom of Cyprus, and Alice of Montbéliard, and was the nephew of John of Ibelin, the "Old Lord of Beirut". To distinguish him from his uncle and other members of the Ibelin family named John, he is sometimes called John of Jaffa.
Cyril III, known as Cyril ibn Laqlaq, was the 75th Coptic Orthodox Pope and Patriarch of Alexandria.
The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land between 1095 and 1291 that had the objective of reconquering Jerusalem and its surrounding area from Muslim rule after the region had been conquered by the Rashidun Caliphate centuries earlier. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries. Crusading declined rapidly after the 15th century.
Odo or Eudes of Châteauroux, also known as Odo of Tusculum and by many other names, was a French theologian and scholastic philosopher, papal legate and cardinal. He was “an experienced preacher and promoter of crusades”. Over 1000 of his sermons survive.
Opizzo Fieschi, also known as Opizo or Opiso dei' Fieschi, was a 13th-century Italian cleric from the powerful Genovese Fieschi family. Following his uncle Sinibaldo's election as Pope Innocent IV, Opizzo was appointed the Catholic Church's patriarch of Antioch.
The Barons' Crusade (1239–1241), also called the Crusade of 1239, was a crusade to the Holy Land that, in territorial terms, was the most successful crusade since the First Crusade. Called by Pope Gregory IX, the Barons' Crusade broadly embodied the highest point of papal endeavor "to make crusading a universal Christian undertaking." Gregory IX called for a crusade in France, England, and Hungary with different degrees of success. Although the crusaders did not achieve any glorious military victories, they used diplomacy to successfully play the two warring factions of the Ayyubid dynasty against one another for even more concessions than Frederick II had gained during the more well-known Sixth Crusade. For a few years, the Barons' Crusade returned the Kingdom of Jerusalem to its largest size since 1187.
The timeline of the Kingdom of Jerusalem presents important events in the history of the Kingdom of Jerusalem—a Crusader state in modern day Israel and Jordan—in chronological order. The kingdom was established after the First Crusade in 1099. Its first ruler Godfrey of Bouillon did not take the title of king and swore fealty to the Latin Patriarch of Jerusalem, Daimbert. Godfrey's brother and successor Baldwin I was crowned the first king of Jerusalem without doing homage to the patriarch in 1100. By 1153, Baldwin I and his successors captured all towns on the Palestinian coast with the support of Pisan, Genoese and Venetian fleets and also took control of the caravan routes between Egypt and Syria. The kings regularly administered other crusader states—the Counties of Edessa and Tripoli and the Principality of Antioch—on behalf of their absent or underage rulers.
Filippo da Pistoia, also called Filippo Fontana or anglicized Philip, was an Italian prelate, military leader and diplomat. He was the bishop-elect of Ferrara from 1239 until 1252, bishop-elect of Florence from 1250 until 1251 and archbishop of Ravenna from 1250 until his death. He was the apostolic legate in Germany between July 1246 and March 1247, in Lombardy and the Trevigiana between December 1255 and August 1258 and throughout northern Italy between 1267 and February 1270. He served as podestà (mayor) of Ravenna in 1254.
Gerold of Lausanne, was abbot of Molesme, abbot of Cluny, bishop of Valence, and Latin patriarch of Jerusalem in the 13th century.
Peter of Limoges was the archbishop of Caesarea from 1199 until his death.
Lando was the archbishop of Reggio in Calabria from 1218 to 1232, and archbishop of Messina from 1232 until his death.
