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.
The Latin Patriarchate of Jerusalem is the Latin Catholic ecclesiastical patriarchate in Jerusalem, officially seated in the Church of the Holy Sepulchre. It was originally established in 1099, with the Kingdom of Jerusalem encompassing the territories in the Holy Land newly conquered by the First Crusade. From 1374 to 1847 it was a titular see, with the patriarchs of Jerusalem being based at the Basilica di San Lorenzo fuori le Mura in Rome. Pope Pius IX re-established a resident Latin patriarch in 1847.
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.
Margaret of Provence was Queen of France by marriage to King Louis IX.
Jacques de Vitry was a French canon regular who was a noted theologian and chronicler of his era. He was elected bishop of Acre in 1214 and made cardinal in 1229. His Historia Orientalis is an important source for the historiography of the Crusades.
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.
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 in the period between 1095 and 1291 that were intended to reconquer Jerusalem and its surrounding area from Muslim rule. 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.
The Eastern Roman (Byzantine) imperial church headed by Constantinople continued to assert its universal authority. By the 13th century this assertion was becoming increasingly irrelevant as the Eastern Roman Empire shrank and the Ottoman Turks took over most of what was left of the Byzantine Empire. The other Eastern European churches in communion with Constantinople were not part of its empire and were increasingly acting independently, achieving autocephalous status and only nominally acknowledging Constantinople's standing in the Church hierarchy. In Western Europe the Holy Roman Empire fragmented making it less of an empire as well.
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.
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.
