group of using the hashish drug, the caliph used the term in a pejorative manner. This label was quickly adopted by anti-Isma'ili historians and applied to the Isma'ilis of Syria and Persia. The spread of the term was further facilitated through military encounters between the Nizaris and the Crusaders, whose chroniclers adopted the term and disseminated it across Europe. To Crusaders, the Fedayeen concept of valuing a principle above your own life was alien to them, so they rationalized it using myths such as the 'paradise legend', the 'leap of faith' legend, and the 'hashish legend', sewn together in the writings of Marco Polo. During the medieval period, Western scholarship on the Isma'ilis contributed to the popular view of the community as a radical sect of assassins, believed to be trained for the precise murder of their adversaries. By the 14th century, European scholarship on the topic had not advanced much beyond the work and tales from the Crusaders. The origins of the word forgotten, across Europe the term assassin had taken the meaning of "professional murderer". In 1603, the first Western publication on the topic of the Assassins was authored by a court official for King Henry IV of France and was mainly based on the narratives of Marco Polo from his visits to the Near East. While he assembled the accounts of many Western travellers, the author failed to explain the etymology of the term Assassin. According to the Lebanese writer Amin Maalouf, based on texts from Alamut, Hassan-i Sabbah tended to call his disciples Asāsīyūn (, meaning "people who are faithful to the foundation [of the faith]"), and derivation from the term hashish is a misunderstanding by foreign travelers. Another modern author, Edward Burman, states that: The name "Assassin" is often said to derive from the Arabic word Hashishin or "users of hashish", which was originally applied to the Nizari Isma'ilis by the rival Mustali Isma'ilis during the fall of the Isma'ili Fatimid Empire and the separation of the two Isma'ili streams. There is little evidence hashish was used to motivate the Assassins, contrary to the beliefs of their Medieval enemies. It is possible that the term hashishiyya or hashishi in Arabic sources was used metaphorically in its abusive sense relating to use of hashish, which due to its effects on the mind state is outlawed in Islam. Modern versions of this word include Mahashish used in
