This paper investigates the Islam and Muslim life in German textbooks. The study is based on the analysis of current Geography textbooks in Bavarian secondary schools. As a first step, the authors developed a system for objective analysis of the textbooks that structures the content in categories. In a second step, the authors used the qualitative method. One category system was developed to analyze the didactical quality of the illustration to the theme Islam and Muslim life another category system was developed to analyze the different aspects of Islam and Muslim life in textbooks. Quantitative analysis shows that the book authors use a variety of illustrations, but especially photos followed by maps. The quality is generally good. Three aspects were selected for qualitative analysis: Spatial representations of Islam, Islam as a religion and Muslim people in Germany. The spatial representation of Islam across the different textbooks is very diverse. Islam is usually not presented as a European phenomenon. The presentation of Islam as an oriental phenomenon risks propagating the idea that there is no other religious group in this area. The information on Islam as a religion is often superficial and may cause students to falsely assume that Islam is a homogeneous religion. Overall, the reader is led to wrongly falsely assume that Muslim migrants, many of whom are living in the 3rd generation in Germany, are still not really part of German society. This is certainly not true for the majority.
