 When the Crusaders invaded and conquered the Levant from the Fatimids in 1099 , al @-@ Lajjun 's Roman name , " Legio " , was restored and the town formed a part of the lordship of Caesarea . During this time , Christian settlement in Legio grew significantly . John of Ibelin records that the community " owed the service of 100 sergeants " . Bernard , the archbishop of Nazareth granted some of the tithes of Legio to the hospital of the monastery of St. Mary in 1115 , then in 1121 , he extended the grant to include all of Legio , including its church as well as the nearby village of Ti 'inik . By 1147 , the de Lyon family controlled Legio , but by 1168 , the town was held by Payen , the lord of Haifa . Legio had markets , a town oven and held other economic activities during this era . In 1182 , the Ayyubids raided Legio , and in 1187 , it was captured by them under the leadership of Saladin 's nephew Husam ad @-@ Din ' Amr and consequently its Arabic name was restored .
