Comparative Prussian history constitutes the methodical focus of the Yearbook. Particular emphasis is placed on the areas east of the rivers Elbe and Saale: during the Middle Ages they produced those Eastern settlements to be merged into the Prussian state in the early modern age, the era that marked the beginnings of the formation of states. Political, judicial and constitutional history, economic and social history, community history, and church, cultural and educational history are all taken into consideration, as well as related disciplines with a historical orientation. A journal review provides a quick insight into the latest research in comparative and Prussian regional history.
