On July 15, 1099, Crusaders conquered the city of Jerusalem and proceeded to massacre the city’s entire Muslim and Jewish population – over 70,000 people.
Seized by a frenzy of vengeful blood lust, the heavily-armed European Christians stormed Jerusalem like wild animals, spilling through the streets of the holy city with swords in their hands and indiscriminately butchering every man, woman, and child they could find. They sacked mosques, broke open stores, and plundered houses. Tens of thousands of Muslims and jews were beheaded, shot with arrows, thrown from towers, tortured, or burned at the stake.
When their killing finally stopped a week later on Friday, July 22, not a single Arab or Muslim could be seen alive within Jerusalem. Tens of thousands of Arabs and Muslims were lying dead in pools of blood in front of their own houses or stores and outside all of the holy city’s mosques, especially around al-Aqsa Mosque, which was shamefully desecrated. It is estimated that more than 70,000 Arabs and Muslims were butchered in cold blood in and around the great mosque of al-Aqsa alone. The Dome of the Rock next to al-Aqsa Mosque was converted to a church by the Crusaders and was stripped of hundreds of silver candelabra and dozens of gold ones.
This marked the end of historic ” First crusade”
