The new Muslim presence in the West has become the source of multiple anxieties. This article, by focusing on one city in the north of England with a Muslim presence which has grown from 3000 to 130,000 in 50 years, considers the resources which state and the established church bring to incorporate such communities in the mainstream of society. The Muslim communities are not presented as passive victims of prejudice and exclusion but as possessed of agency. This paper concludes that there are expressions of Islam which are easy to incorporate but others which generate an isolationist mindset which can create major problems.
