Published in honor of historian Geoffrey Parker, this volume explores the working of European empires in a global perspective, focusing on one of the most important themes of Parker¿s work: the limits of empire, which is to say, the centrifugal forces - sacral, dynastic, military, diplomatic, geographical, informational - that plagued imperial formations in the early modern period (1500-1800). Whilst the thirteen chapters in this book focus on a number of geographic regions and adopt different approaches, each shares a focus on, and interest in, the working of empires and the ways that imperial formations dealt with - or failed to deal with - the challenges that beset them. Taken together, they reflect a new phase in the evolving historiography of empire.
