This collection expands previous regional and individual studies of queenship and female political agency in order to engage in a comparative study of premodern female rule on a global scale. While the field of queenship studies and examinations of gender and power have been flourishing, the literature has tended to be dominated by studies of European royalty. This volume aims to embrace and develop the trend towards an increasingly global outlook for the field of queenship studies. Case studies of women from different periods, places, and religions are deliberately mixed to compare and contrast the realities of queenship in varied settings. Lesser studied examples of queens are provided alongside fresh perspectives on more familiar figures and regions. The authors increase our understanding of understudied individuals and groups of queens, and they encourage the comparison of the practice of queenship in the premodern era. This authoritative and comprehensive Companion will be required reading for all scholars and students of premodern gender and political studies.
