The Kingdom of Jerusalem, also known as the Latin Kingdom, 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 fall 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.
The 1100s was a decade of the Julian Calendar which began on January 1, 1100, and ended on December 31, 1109.
Year 1110 (MCX) was a common year starting on Saturday of the Julian calendar.
Baldwin I was the first count of Edessa from 1098 to 1100 and king of Jerusalem from 1100 to his death in 1118. He was the youngest son of Eustace II, Count of Boulogne, and Ida of Lorraine and married a Norman noblewoman, Godehilde of Tosny. He received the County of Verdun in 1096, but he soon joined the crusader army of his brother Godfrey of Bouillon and became one of the most successful commanders of the First Crusade.
The Battle of Hattin took place on 4 July 1187, between the Crusader states of the Levant and the forces of the Ayyubid sultan Saladin. It is also known as the Battle of the Horns of Hattin, due to the shape of the nearby extinct volcano of that name.
Raymond III was count of Tripoli from 1152 to 1187. He was a minor when Nizari Assassins murdered his father, Raymond II of Tripoli. Baldwin III of Jerusalem, who was staying in Tripoli, made Raymond's mother, Hodierna of Jerusalem, regent. Raymond spent the following years at the royal court in Jerusalem. He reached the age of majority in 1155, after which he participated in a series of military campaigns against Nur ad-Din, the Zengid ruler of Damascus. In 1161 he hired pirates to pillage the Byzantine coastline and islands to take vengeance on Byzantine emperor Manuel I Komnenos, who had refused to marry his sister Melisende. He was captured in the Battle of Harim by Nur ad-Din's troops on 10 August 1164, and imprisoned in Aleppo for almost ten years. During his captivity, Amalric I of Jerusalem administered the county of Tripoli on his behalf.
The siege of Acre was the first significant counterattack by Guy of Jerusalem against Saladin, leader of the Muslims in Syria and Egypt. This pivotal siege formed part of what later became known as the Third Crusade. The siege lasted from August 1189 until July 1191, in which time the city's coastal position meant the attacking Latin force were unable to fully invest the city and Saladin was unable to fully relieve it with both sides receiving supplies and resources by sea. Finally, it was a key victory for the Crusaders and a serious setback for Saladin's ambition to destroy the Crusader states.
The Battle of Azaz was a major battle fought between king Baldwin II's crusader forces and the Muslims, led by Aq-Sunqur al-Bursuqi, the Seljuq atabeg of Mosul on 11 June 1125. Being one of the bloodiest confrontations before the Second Crusade, the battle resulted in a decisive victory for the Crusaders, causing disturbances of power in the Levant and weakened Seljuk domination in the area. Contemporary chronicler Matthew of Edessa even states that the remnants of al-Bursuqi's army were chased all the way to Aleppo. The battle effectively lifted the siege of the town of Azaz and prevented it from falling to Turkoman hands.
The Siege of Jerusalem marked the successful end of the First Crusade, whose objective was the recovery of the city of Jerusalem and the Church of the Holy Sepulchre from Islamic control. The five-week siege began on 7 June 1099 and was carried out by the Christian forces of Western Europe mobilized by Pope Urban II after the Council of Clermont in 1095. The city had been out of Christian control since the Muslim conquest of the Levant in 637 and had been held for a century first by the Seljuk Turks and later by the Egyptian Fatimids. One of the root causes of the Crusades was the hindering of Christian pilgrimages to the Holy Land which began in the 4th century. A number of eyewitness accounts of the battle were recorded, including in the anonymous chronicle Gesta Francorum.
The Battle of Ascalon took place on 12 August 1099 shortly after the capture of Jerusalem, and is often considered the last action of the First Crusade. The crusader army led by Godfrey of Bouillon defeated and drove off a Fatimid army.
The siege of Ascalon took place from 25 January to 22 August 1153, in the time period between the Second and Third Crusades, and resulted in the capture of the Fatimid Egyptian fortress by the Kingdom of Jerusalem. Ascalon was an important castle that was used by the Fatimids to launch raids into the Crusader kingdom's territory, and by 1153 it was the last coastal city in Palestine that was not controlled by the Crusaders.
The Complete History, is a classic Islamic history book written by Ali ibn al-Athir. Composed in ca. 1231AD/628AH, it is one of the most important Islamic historical works. Ibn al-Athir was a contemporary and member of the retinue of Saladin, the Sultan of Egypt who captured Jerusalem from the Crusaders and massively reduced European holdings in the Levant, leaving the Principality of Antioch and County of Tripoli much reduced and only a few cities on the coast to the Kingdom of Jerusalem.
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 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.
Mawdud ibn Ahmad was an Arab Muslim military leader who was atabeg of Mosul from 1109 to 1113. He organized several expeditions to reconquer lands from the Crusaders and defeated them at the Battle of Al-Sannabra.
The Norwegian Crusade, led by Norwegian King Sigurd I, was a crusade or a pilgrimage that lasted from 1107 to 1111, in the aftermath of the First Crusade. The Norwegian Crusade marks the first time a European king personally went to the Holy Land.
The siege of Tyre took place from 12 November 1187 to 1 January 1188. An army commanded by Saladin made an amphibious assault on the city, defended by Conrad of Montferrat. After two months of continuous struggle, Saladin dismissed his army and retreated to Acre.
The navy of the Fatimid Caliphate was one of the most developed early Muslim navies and a major force in the central and eastern Mediterranean in the 10th–12th centuries. As with the dynasty it served, its history is in two phases. The first was c. 909 to 969, when the Fatimids were based in Ifriqiya ; the second lasted until the end of the dynasty in 1171, when they were based in Egypt. During the first period, the navy was employed mainly against the Byzantine Empire in Sicily and southern Italy, where it enjoyed mixed success. It was also in the initially unsuccessful attempts to conquer Egypt from the Abbasids and brief clashes with the Umayyad Caliphate of Córdoba.
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.
The siege of Acre took place in May 1104. It was of great importance for the consolidation of the Kingdom of Jerusalem, which had been founded only a few years earlier. With the help of a Genoese fleet, King Baldwin I forced the surrender of the important port city after a siege that lasted only twenty days. Although all defenders and residents wishing to leave the city had been assured by the king that they would be free to leave, taking their chattels with them, many of them had been massacred by the Genoese as they left the city. Moreover, the attackers had also sacked the city itself.
The siege of Beirut was an event in the aftermath of the First Crusade. The coastal city of Beirut was captured from the Fatimids by the forces of Baldwin I of Jerusalem on 13 May 1110, with the assistance of Bertrand of Toulouse and a Genoese fleet.
