The Religious Peace of Augsburg was celebrated in considerable style in Germany on its 450th anniversary in 2005 – an indication not simply of its historical significance, but of more recent interpretations as well, which emphasise the political and legal resilience of the Holy Roman Empire as a constitutional polity, and which reflect contemporary ecumenical concerns. To the major exhibition in Augsburg, Als Frieden möglich war, with its lavish catalogue, there is now added a compact survey of the impact of the Peace on the various territories of the empire. This volume does not aim to be comprehensive, yet finds space for distinct oddities such as Karel Halla's pious rehearsal of the history of the Protestant enclave of Asch in eastern Bavaria. Against that, the essays by Armin Kohnle on the Palatinate and Baden, or Hermann Ehmer on Württemberg, offer succinct overviews of the altogether complex twists and turns of confessional allegiance in the German south-west. Equally, Inge Mager provides a good introduction to the fortunes of the north German ecclesiastical territories. Not all the essays achieve a high standard: Heiner Lück on imperial law has no insights to offer which are not already available in the writings of Martin Heckel. In its approach the volume at first sight seems consciously to echo the encyclopaedic seven-volume survey of the territories of the empire in the age of Reformation and confessionalisation edited by Anton Schindling and Walter Ziegler, an indispensable research tool. In truth, the present volume is too brief and too miscellaneous to offer more than a starting-point for further investigation.
