A new account of racial logics in premodern Islamic literature.   In Black Knights, Rachel Schine reveals how the Arabic-speaking world developed a different form of racial knowledge than their European neighbors during the Middle Ages. Unlike in European vernaculars, Arabic-language ideas about ethnic difference emerged from conversations extending beyond the Mediterranean, from the Sahara to the Indian Ocean. In these discourses, Schine argues, racialized blackness became central to ideas about a global, ethnically inclusive Muslim world. Schine traces the emergence of these new racial logics through popular Islamic epics, drawing on legal, medical, and religious literatures from the period to excavate a diverse and ever-changing conception of blackness and race. The result is a theoretically nuanced case for the existence and malleability of racial logics in premodern Islamic contexts across a variety of social and literary formations.
