Today, a number of European states’ policies on religion aim at creating a nationalized Islam. In many Western European countries, the Ministries of the Interior have institutionalized ‘dialogue platforms’ to discuss issues of Islam, society, inclusion and extremism with Muslim actors. This reveals the implicit assumptions of these governments when talking to Muslims. The underlying message is that Muslims pose a security threat to the state and society, a perception that is manifested in many countries, and that Muslims are seen simultaneously as a threat and an ally. This article analyzes the Ministry of Interior’s attempts to institutionalize Islam in the cases of Austria, Germany, and France and it compares these states in order to investigate different modes of operation, similarities and differences.
