Christendom launches the Crusade Wars against Muslims
On June 7, 1099 AD, the Crusader invaders from Europe laid siege to the Islamic city of Bayt al-Moqaddas, which they called Jerusalem and captured it a month and a week later on July 15. A year earlier these European invaders taking advantage of discord among the Muslims, especially the enmity of the Turkic warlords with the Fatemid Shi’ite Muslim rulers of Egypt who controlled most of Syria including Palestine, had captured Antioch. Then moving along the Mediterranean coast they laid siege to Arqa until May 13 but could not capture it. The Fatemids took up the proposal of peace on condition that the crusaders do not march upon Bayt al-Moqaddas, but this was ignored.
Iftekhar od-Dawla, the Fatemid governor of Bayt al-Moqaddas, becoming aware of motives of the Crusaders strengthened the defences of the city. Meanwhile, the Crusaders were given money and horses by the Turkic ruler of Tripoli, who also promised to convert to Christianity if they capture Bayt al-Moqaddas from the Fatemids. The Crusaders thus succeeded in passing unopposed through Beirut on May 19, Tyre on May 23, and turning inland at Jaffa, reached Ramlah on June 3, which had already been abandoned by its inhabitants. On June 6, they seized Bayt-Laham, and the next day reached the outskirts of Bayt al-Moqaddas. Iftekhar od-Dawla resisted but no reinforcements arrived from Egypt.
Many Muslims sought shelter in the Al-Aqsa Mosque, and the Dome of the Rock. When the city was starved and forced to surrender, the Crusaders broke all promises and started slaughtering the Muslim men, women, and children. In all, over 70,000 people were massacred including Palestinian Christians and the Jewish minority. According to their own accounts, the Crusaders boasted of wading in blood up to their ankles, while killing Muslims. It is stated that when the Jews sought refuge in their synagogue, the Crusaders burned it over their heads, killing everyone inside. It took Muslims over eight decades to liberate Qods through a united army of Kurds, Turks, Arabs and Persians to end the 88-year illegal existence of the Latin Kingdom of Jerusalem.
