In 1804, Francis II was forced by Napoleon to abdicate his position as Holy Roman Emperor. Instead, he became the Emperor of a new nation state, Austria-Hungary. Within his borders, he ruled a people of vast ethnic diversity including Germans, Hungarians, Czechs, Slovaks, Croats, Ukrainians, Poles, Russians, Rumanians, Italians, and Belgians. This book encapsulates the history of this thrown-together nation state and examines its soldiers as they battled throughout the Napoleonic Wars, covering all of the major campaigns and battles in which they fought.
