Religious strife in Europe, caused by the Reformation, isolating the Catholics and providing European allies to the Ottoman Empire. Superior military tactics. After four centuries of continuous rule, the Ottoman Empire collapsed, creating a vacuum that contributed to tensions between local inhabitants and external powers or interests. In the book I try to foreground the anxieties that led to this kind of conclusion, this attempt to remake society. I try to not over-attribute the collapse of the Ottoman Empire to contemporary affairs.
