This book discusses a black blox within the design process of history textbooks: the admission procedure. For this purpose, the author analyzes biographicals sources of relevant actors and over sixty admission procedures in Bavaria as well as history textbooks, published between 1949 and the 1970s. The negotiation of historical culture regarding national socialism is the thematic reference point of the book. The author illustrates, how institutional, normative and personnel conditions, influenced the hegemonic historical culture within textbooks. It shows, that the outcome of most approval procedures harmonized historical culture. However, the approvals itself were quite randomized. This situation was caused by the way, the reviewers were chosen, because most of these only approved one or two textbooks. Nevertheless, the reviewers functioned as “goalkeepers” to an official historical culture. For this very reason, admission procedures were battlegrounds for the fight about the interpretative dominance regarding national socialism.
