This book explains the role of religion in peace and conflict in contemporary European society. It confirms the idea that multiculturalism is a dead concept because it is too static. The main link between all of the chapters of the book is the idea that European society is segregated, especially along the axes of religious and ethnic belonging. Because of this, religious nationalism, which is especially characteristic for Christian and Islamic religious institutions, is becoming stronger. The much more dynamic principle of interculturalism is based on this concept. The book presents a message to the political and religious elites of Europe to build one society for all and interculturalism instead of furthering the ideologies of ethno-nationalism and religious nationalism. A part of this text is dedicated to the situation in Africa in comparison to Europe.
