Islam has emerged as the focus of immigration and diversity debates in Europe, especially in relation to the incorporation of Islam within political democracy. Using the least-liked group approach, the present study investigates political tolerance among Sunni and Alevi Muslims of Turkish origin living in Germany and the Netherlands. A relatively low level of political tolerance was found with higher intolerance of Alevis compared to Sunnis which was due to Alevis' strong rejection of religious fundamentalists. For both Muslim subgroups and in both countries, stronger religious group identification was associated with higher tolerance. Political tolerance was also found to be lower in Germany than in the Netherlands and in the latter country tolerance was positively associated with host national identification. The findings show that Islamic belief, Muslim group identification and the host national context are important for political tolerance.
