Byzantine Empire by the
Seljuqs, led to the
First Crusade.
Europeans marched to recover the
Holy Land, and on July 15, 1099, Christian soldiers were victorious in the one-month
Siege of Jerusalem. In keeping with their alliance with the Muslims, the Jews had been among the most vigorous defenders of Jerusalem against the Crusaders. When the city fell, the Crusaders slaughtered most of the city's Muslim and Jewish inhabitants, leaving the city "knee deep in blood". Jerusalem became the capital of the
Kingdom of Jerusalem. Christian settlers from the
West set about rebuilding the principal shrines associated with the life of Christ. The
Church of the Holy Sepulchre was ambitiously rebuilt as a great
Romanesque church, and Muslim shrines on the Temple Mount (the
Dome of the Rock and the Al-Aqsa Mosque) were converted for Christian purposes. The
Military Orders of the
Knights Hospitaller and the
Knights Templar were established during this period. Both grew out of the need to protect and care for the great influx of pilgrims traveling to Jerusalem, especially since
Bedouin enslavement raids and terror attacks upon the roads by the remaining Muslim population continued. King
Baldwin II of Jerusalem allowed the forming order of the Templars to set up a headquarters in the captured Al-Aqsa Mosque. The Crusaders believed the Mosque to have been built on top of the ruins of the
Temple of Solomon (or rather his royal palace), and therefore referred to the Mosque as "Solomon's Temple", in
Latin "Templum Solomonis". It was from this location that the Order took its name of "Temple Knights" or "Templars".
Mappa Mundi (c. 1280), depicting Jerusalem at the center of the world Under the Kingdom of Jerusalem the area experienced a great revival, including the re-establishment of the city and harbour of
Caesarea, the restoration and fortification of the city of
Tiberias, the expansion of the city of
Ashkelon, the walling and rebuilding of
Jaffa, the reconstruction of
Bethlehem, the repopulation of dozens of towns, the restoration of large agriculture, and the construction of hundreds of churches, cathedrals, and castles. The old
hospice, rebuilt in 1023 on the site of the
monastery of Saint John the Baptist, was expanded into an infirmary under Hospitaller grand master
Raymond du Puy de Provence near the
Church of the Holy Sepulchre. In 1173
Benjamin of Tudela visited Jerusalem. He described it as a small city full of
Jacobites,
Armenians,
Greeks, and
Georgians. Two hundred
Jews dwelt in a corner of the city under the
Tower of David. In 1187, with the Muslim world united under the effective leadership of
Saladin, Jerusalem was re-conquered by the Muslims after a successful
siege. As part of this same campaign the armies of Saladin conquered, expelled, enslaved, or killed the remaining Christian communities of
Galilee,
Samaria,
Judea, as well as the
coastal towns of Ashkelon, Jaffa, Caesarea, and
Acre. In 1219 the walls of the city were razed by order of
Al-Mu'azzam, the
Ayyubid sultan of Damascus. This rendered Jerusalem defenseless and dealt a heavy blow to the city's status. Following another
Crusade by the
Holy Roman Emperor Frederick II in 1227, the city was surrendered by Saladin's descendant
al-Kamil, in accordance with a diplomatic
treaty in 1228. It remained under Christian control, under the treaty's terms that no walls or fortifications could be built in the city or along the strip which united it with the coast. In 1239, after the ten-year truce expired, Frederick ordered the rebuilding of the walls. But without the formidable Crusader army he had originally employed ten years previous, his goals were effectively thwarted when the walls were again demolished by
an-Nasir Da'ud, the emir of
Kerak, in the same year. In 1243 Jerusalem was firmly secured into the power of the Christian Kingdom, and the walls were repaired. However, the period was extremely brief as a large army of Turkish and Persian Muslims was advancing from the north. ==Khwarezmian control==
