Students of the Mamluk Sultanate generally do not refer to the phenomenon of mamluks (i.e., slaves, and more specifically military slaves) of Jewish origin. David Ayalon noted that “there is hardly any trace of a Mamlūk of Jewish origin in the Mamlūk sultanate.” Moreover, it is thought that Jews were not considered suitable for warfare. This article surveys mamluks of Jewish origin that can be identified in Mamluk sources. Gaps in information about their geographical origin, which is usually lacking in Mamluk sources, will be filled with information given by European travelers or that can be deduced from the names given to them as slaves.
