Various western historical writers have sometimes used the term dervish rather loosely, linking it to, among other things, the Mahdist War in Sudan and other conflicts by Islamic military leaders. In such cases, the term “dervishes” may have been used as a generic (and often pejorative) term for the opposing Islamic entity and all members of its military, political and religious institutions, including persons who would not be considered “dervishes” in the strict sense.
