In little more than two centuries Prussia rose from medieval obscurity and the devastation of the Thirty Years War to become the dominant power of continental Europe. Her rulers rose from Electors to Kings, and from Kings to Emperors. It is a dramatic story, and H. W. Koch fills a major gap in English-language literature with this comprehensive account. It traces the origins and rise of the Prussian state from the thirteenth century to the causes and consequences of its incorporation into the German Empire.
