Eyewitnesses who have never been interviewed, documents that have never been published and photos that have never been shown document the rise of a small community of Muslims in the 1950s to become a central hub of Islamism in Germany and the Western world. Completely unknown in this context: the founding of this Islamic community was the result of a secret political conspiracy led by former Nazi functionaries in the Bonn Ministry for Expellees under Theodor Oberländer (CDU). However, the project got out of hand; it was not German authorities but members of the Muslim Brotherhood who gained control and developed the community into a base for Islamism in Europe.
