In 1079, the Tutush I of Damascus besieged but failed to capture Tall Mannas during his campaign in northern Syria. Later, in 1098/97 Tall Mannas was inhabited by Christian community of Oriental Orthodox Syriacs and its inhabitants gave safe haven and assistance to the Crusaders under Raymond Pilet of Antioch during their failed siege of Ma'arrat al-Nu'man. Some months later, Ma'arrat al-Nu'man was captured and its entire population massacred by the Crusaders.
