Using the data of the EURISLAM project, this article investigates the impact of dramatic events on the public debate with regard to Islam in Belgium, the Netherlands, France, Germany, Switzerland and the UK. It assesses the extent to which dramatic events such as 9/11, the bombings in Madrid and London and the murder of Theo Van Gogh in Amsterdam impacted on the debate on multiculturalism, notably the accommodation of Western-European institutions to Islam. In this contribution, we analyse the overall evolution of public debate in the written press on Muslims, and more particularly Muslim rights, for the period 1999-2009. Our aim is to empirically analyse the transitions that the public debate on Islam in Europe has undergone in the wake of the most dramatic terrorist acts perpetrated by Muslim extremists during the last decade. We hypothesize that dramatic violent events involving Muslim extremists had an impact on the number of claims about Muslims and Islam in general, but not on the debate about religious rights for Muslims in Europe. Descriptive analysis and time series plus intervention analysis were undertaken to test these hypotheses. 1 Ethnicities 13(2) 209-228
