Der Dreißigjährige Krieg by C. V. Wedgwood

A vivid, tightly argued narrative of the cataclysmic European conflict of the early 17th century, tracing how a local religious dispute in Bohemia escalated into a continent-wide war involving dynastic ambitions, shifting alliances, and mercenary armies; the account emphasizes the political maneuvering, military campaigns, and the devastating impact on civilian populations—famine, disease, and depopulation—culminating in the diplomatic settlements that reshaped the map of Europe and the concept of state sovereignty.
