متى خسر المسيحيون القدس؟

That is correct! The capture of Jerusalem by the Crusaders during the First Crusade in July 1099 marked the establishment of the medieval Kingdom of Jerusalem.

Nearly a century later, following his decisive victory at the Battle of Hattin in July 1187, Saladin led the forces of the Ayyubid Dynasty to besiege Jerusalem, ultimately accepting the city's surrender from Balian of Ibelin on October 2, 1187. This event triggered the Third Crusade as European powers sought to recapture the city.
