Early 12th century- The Franks assume control of the Citadel of Salah-ed-Din as part of the newly formed Crusader state of the Principality of Antioch. The Principality is one of the 4 states founded after the First Crusade. The Crusaders begin an extensive building programme, giving the castle much of the appearance it will keep into the 21st century. In 1188, it will fall to the forces of Saladin after a 3-day siege.
