This chapter uncovers the history of the Gesamtarchiv der deutschen Juden, the central archive of the German Jews, which operated from 1903 until it was confiscated by the Nazis in 1943. It details the Gesamtarchiv’s attempt to create a singular archive of German Jewish history in Berlin, and also opposition to the project of centralization, and it situates the archive within the wider trends of archival science. It thereby explicates the Gesamtarchiv’s vision of total archives and traces its legacy across the arc of the twentieth century. This archive was intended to help produce the history of Germany’s Jews and also to help manage its communities, but it was ultimately turned into an instrument for the domination of Jewish life by the Nazi regime. Altogether, this chapter offers the Gesamtarchiv as a starting point for a global network of Jewish archives that followed the Gesamtarchiv’s vision of archival totality.
