Migration is the most significant characteristics of Europe after World War II. In many European countries, in particular in Western Europe, it has led to multiethnic societies with special integration problems but only in more recent times its impact for multireligious pluralism was discovered in social sciences studies. It is therefore necessary to have a closer look at both: multiethnicity and religious pluralism and its respective consequences for the social peaceful living together in society, especially as concerns present-day Germany.
