Timeline of the Kingdom of Jerusalem

The timeline of the Kingdom of Jerusalem presents important events of the history of the Kingdom of Jerusalema crusader state in Palestinein chronological order. The kingdom was established during the First Crusade. Its first ruler, Godfrey of Bouillon, was not crowned king and swore fealty to the Latin Patriarch of Jerusalem, Daimbert in 1099. Godfrey's brother and successor, Baldwin I, who did not acknowledge the patriarchs' sovereignty, was crowned the first king of Jerusalem in 1100. Baldwin I and his successors captured all towns on the 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 statesthe Counties of Edessa and Tripoli, and the Principality of Antiochon behalf of their absent or minor rulers.
The polarisation of the Muslim world enabled the crusaders (or Franks) to consolidate their rule in Palestine. They could also appeal to the Popes and the European rulers for help against their enemies. Baldwin III and Amalric maintained a close alliance with the Byzantine Empire, but they could not prevent the ruler of Aleppo, Nur ad-Din from uniting the Muslim states in Syria in the 1150s. Internal strives weakened the kingdom during the reigns of the leper Baldwin IV and the unpopular Guy of Lusignan, which enabled Nur ad-Din's former general, Saladin to unite Egypt and Syria in the 1180s. Saladin annihilated the crusader army in the Battle of Hattin on July 4, 1187 and occupied almost the whole kingdom during the following months.
An Italian crusader, Conrad of Montferrat, saved Tyre and the Third Crusade forced Saladin to acknowledge the restoration of the Franks' rule in most coastal towns in his 1192 truce with Richard I of England. Further lands were recovered during the reigns of Henry of Champagne and Aimery of Lusignan, and Frederick II, Holy Roman Emperor, also restored the Franks' rule in Jerusalem in 1229. Frederick and his successors were absent monarchs and the kingdom was administered by regents (or baillifs) from 1229 to 1269. Due to conflicts between the kings' representatives and the powerful barons, and the War of Saint Sabas between Genoa and Venice, the kingdom disintegrated into autonomous towns and lordships by the 1260s. The personal union of Jerusalem and Cyprus could not prevent the Mameluks of Egypt from occupying the last Frank outposts in 1291.
Local Muslims and Christians made up the majority of the population in the countryside, but European—mainly French, Italian and Catalan—colonists also settled in the villages. Sugar refinery, based on local sugarcane plantations, developed into an important industry.
