The Fischer controversy of the 1960s was a major landmark in post-war West German historiography. Surprisingly few historians to date have devoted their attention to the East German reception of Fischer's work, however. This article seeks to fill this gap by looking at some of the critical reviews published in East German academic journals and also at internal records from the Socialist Unity Party archive. Particular emphasis is placed on the period after 1965 when East German scholars began to explore the historiographical and national implications of the Fischer controversy with a greater degree of sensitivity but also with a greater degree of caution (for strategic political reasons). A mutually beneficial exchange of ideas between Fischer and German Democratic Republic scholars working on the First World War continued throughout the 1970s and 1980s, although ironically this was at a time when both sides were moving ever further away from the idea of a possible reunification of the two Germanies in the future.
