We are accustomed to associate the concept of military-spiritual brotherhoods exclusively with the Christian religious, cultural, and ideological tradition. However, these ideas, ingrained in the minds of many, turn out to be just another myth. Analogies can be drawn with the actions of modern militant Islamists. whose “martyrs” - “martyrs for the faith” - draw strength from traditions rooted in the era of confrontation between Christianity and Islam, secret military-spiritual brotherhoods of the Near and Middle East - a region that from time immemorial to this day remains a “powder keg” , the epicenter of ongoing military-political conflicts that are disturbing the whole world, and at the same time an arena of constant interaction between civilizations. The reader will learn about this and much more from the next book by our author, historian Wolfgang Akunov, published in the series “Documents and materials of the ancient and modern history of the Sovereign Military Order of the Temple of Jerusalem.”
