In medieval Europe, the death of a king could not only cause a dispute about the succession, but also a severe crisis. In times of a vacant throne particular responsibility fell to the bishops - whose general importance for the time around the first milennium has been revealed by recent scholarship - as royal counsellors and policy makers. This volume therefore concentrates on the bishops' room for manoeuvre and the patterns of episcopal power, focusing on the Eastern Frankish Reich and Anglo-Saxon England in a comparative approach which is not least based upon the research of a renowned medievalist, Timothy Reuter. His article about "e;A Europe of Bishops"e; ("e;Ein Europa der Bischofe"e;) is presented in English translation for the first time.
