This article examines the state secretaries’ meetings as an instrument of government in Nazi Germany. They are mostly known as the forum at which the infamous Wannsee Conference took place, but here the 20 January 1942 meeting will be situated in a context previously ignored by historians by showing that such gatherings were an increasingly regular occurrence during the ‘Third Reich’, and that a range of policy issues were discussed there – not just mass murder. As such, it will shed new light on how the ‘Hitler state’ functioned at this level by showing that Wannsee was not entirely extraordinary, the format having become established practice long before 1942. Similarly, the article will also show that the jurisdictional conflicts that played out at Wannsee were equally common, with participants generally jockeying for influence and advancing claims to departmental authority. Indeed, although they effectively replaced cabinet meetings, which were formally banned by Hitler in 1938, the state secretaries’ meetings did little to salvage collegial government. To illustrate this, a series of meetings called to coordinate the government's response to a particular issue will be examined – the annexation of ‘Greater German’ territories in Austria, the Sudetenland and Poland. As will be shown throughout, very little was achieved by way of coordination, with the state secretaries only advancing those constitutional designs that served their ministries’ claims to power.
