 As a result of Bülow's efforts, between 1923–27 the German Foreign Ministry published forty volumes of documents, which as the German-Canadian historian Holger Herwig noted were carefully edited to promote the idea that the war was not the fault of one nation but were rather the result of the breakdown of international relations.Certain documents such as some of the papers of the Chancellor Theobald von Bethmann Hollweg which did not support this interpretation were destroyed.Hermann Kantorowicz, one of the few German historians who argued in the 1920s that Germany was responsible for the war, found that the Foreign Ministry went out of its way to stop his work from being published and tried to have him fired from his post at Kiel University.
