This book is the first attempt to provide a global view on the phenomenon of Islamism from its beginning in Medina under the Prophet Muhammad to its new forms with the 'Caliphate' of Abu Bakr al-Baghdadi and the 'Imamate' of Ayatollah Khamenei. It demonstrates that all Islamists: Shia, Sunni, Salafi or Jihadi are aiming the same goal: The conquest of the world and the restauration of the Islamist World Empire by all means. Is this only a utopia? Not in Islamist optic. Islamists consider the fall of the Soviet Empire and the unprecedented crisis in Europe, due to the massive Muslim immigration, as the crepuscular of the collapse of the existing world order. The reader finds in this book an elaborated discussion on strength and weakness of Islamist world project.
