The process of social integration of the people associated with immigrant organisations, and the social (and potentially religious) change that comes with it, present the organisations with the difficult challenge of justifying their legitimacy to various societal actors. This is certainly true of Muslim organisations in Western immigration societies. In Germany, this process is quite clearly reflected within the community of established organisations, which play a part in creating intergenerational change. This is not to say, however, that they will be the only relevant – or even the predominant – actors involved in establishing Islam in Germany in the future, despite their roots in their countries of origin, nor that they will automatically become redundant over time.
