Sections of Syria were held by French, English, Italian and German overlords between 1098 and 1189 AD during the Crusades and were known collectively as the Crusader states among which the primary one in Syria was the Principality of Antioch. The coastal mountainous region was also occupied in part by the Nizari Ismailis, the so-called Assassins, who had intermittent confrontations and truces with the Crusader States. Later in history when "the Nizaris faced renewed Frankish hostilities, they received timely assistance from the Ayyubids."
