The Third and Fourth Crusades
The Third Crusade
The Crusader States had endured from 1099 to 1187 because the Muslim Middle East was politically fragmented. Once Saladin had overthrown Egypt’s Fatimid Caliphate and united Egypt to Muslim controlled Syria and northern Iraq (see Chapter Eight), he was able to turn his resources to destroying the Crusader States. Eventually, at the 1187 Battle of Hattin, his forces met the combined forces of the Kingdom of Jerusalem. The result was a complete victory for Saladin. With the manpower of most of the Kingdom of Jerusalem killed or captured—knights and noble prisoners would be held for a hefty ransom, while lower-ranked soldiers would go to slave markets—he was easily able to capture most of the castles and cities that made up the kingdom, to include the city of Jerusalem itself.
The result shocked the Christian world, and Pope Gregory VIII quickly issued the bull (that is, an official papal pronouncement) Audita tremendi, which called on the Christian world to retake Jerusalem. The kings of England and France, Richard I (known as Lionheart, r. 1189 – 1199) and Philip Augustus (r. 1180 – 1223), respectively, took vows to launch a crusade, as did Holy Roman Emperor Frederick Barbarossa. (As usual, the Christians of Iberia took little part in crusades in the Levant, as their efforts focused on the Reconquista.)
Although Frederick Barbarossa died en route (he drowned in a stream in the mountains of Anatolia), both Richard I and Philip Augustus eventually arrived in the Levant by sea. Although Philip soon returned to France, King Richard battled Saladin over the course of two years, to results that were mostly inconclusive. The crusading army seized most of the castles and cities on the coast, and these became the center for a restored, but smaller Kingdom of Jerusalem, but the Crusaders ultimately failed to take Jerusalem itself. The Crusade finally ended in a truce in which both parties ratified this state of affairs, with Christian pilgrims allowed to visit the city of Jerusalem, even though it remained under Muslim rule.
The Fourth Crusade
While Jerusalem remained under Muslim control, the papacy’s goal was to retake it, especially as, in 1198, the man elected pope was one of the most ambitious men to wear the papal crown of the Middle Ages: Pope Innocent III (r. 1198 – 1216). Innocent’s goals were to morally reform society and to launch a crusade for retaking the holy city of Jerusalem. In the year of his election, he issued a call to crusade that ended up as a disaster.
Between 1185 and 1204, the Byzantine Empire had drastically weakened. After the death of Manuel Komnenos with his heir still a child, the Empire faced a string of catastrophes. The child-emperor was murdered, his successor was eventually overthrown, and the next emperor after that was likewise overthrown. During this political infighting, the Empire’s peripheral territories of Serbia, Cyprus, and Cilicia all seceded. Closer to the center, the Bulgars rose in rebellion in 1186 and re-established an independent Bulgaria within only a few days’ march of Constantinople itself. In addition, the chain of emperors, regents, and usurpers reigning between 1185 and 1204 had allowed the Byzantine navy to gradually disintegrate.
In 1202, a group of crusaders (with kings notably absent) contracted with the government of Venice to transport them to fight in Egypt, now ruled by Saladin’s heirs. When these crusaders proved unable to pay, the Venetian government requested their military assistance. The son of the deposed emperor (whose eyes had been gouged out) approached the crusaders and Venetians. He offered the crusaders military and financial assistance and for Venice to gain trading privileges in the Empire if crusaders and Venetians would help him regain his throne. The end result was that, in 1204, after a series of misadventures, a crusader army stormed the walls of Constantinople and put the city to a brutal sack; then, the crusaders parceled out much of the territory of the Byzantine Empire amongst themselves. The most advantageous ports went to Venice, which would use them as the basis of a Mediterranean trading empire that would endure for centuries. The Crusades, which had begun as a result of an appeal for help by the Byzantine Empire, ultimately resulted in its destruction.
Although the Byzantine Empire had been broken up, three states survived that claimed to be legitimate heirs to the Byzantine State. One was established in Western Anatolia with its capital in Nicaea, another, in Epirus, in what is today the country of Albania, while the third was based on the city of Trebizond, on the northern coast of Anatolia. The Nicene Empire would eventually retake Constantinople in 1261, although the restored state would never be the regional power that the Empire had been under the Komnenoi.
