Religion in Global Politics [PDF ebook] 

One of the most resilient ideas about societal development after World War II was that nations would inevitably secularise as they modernised. However, as we come to the end of the “secular“ twentieth century, it is obvious that religion continues to be an important factor in politics around the world. The author examines the continuing importance of religion, focusing upon the regions of Europe, the Americas, Africa, and Asia.
