Friese graafschappen tussen Zwin en Wezer

Published in 2012 by Van Gorcum, this scholarly monograph by Dirk Jan Henstra explores the historical development of the Frisian counties situated between the Zwin and the Weser estuaries. The work was commissioned and written as a detailed academic investigation into the socio-political structures, administrative systems, and territorial shifts of the High Middle Ages in the coastal regions of the Low Countries and northern Germany.

Henstra, a recognized historian in the field of medieval Frisian history, sought to provide a comprehensive synthesis of complex legal and administrative records that had previously been fragmented. The design and layout follow the standard conventions of academic historical publishing, focusing on clarity, evidentiary rigor, and extensive footnoting. It was received by the historical community as a vital reference for understanding the distinctive decentralized governance models that characterized Frisian history during the medieval period.
