This book investigates the political and diplomatic motivations that drove the escalation and sustainment of the First World War. David Stevenson, a historian specializing in international conflict, utilizes recently declassified archival materials to challenge the focus on military tactics alone. He argues that the war was fundamentally a political endeavor, examining how government objectives, the expansion of global alliances, and the failure of diplomatic compromise shaped the conflict and its eventual resolution.

Historians and scholars frequently cite this work as a foundational text for understanding the diplomatic complexities of the Great War. Readers often note the academic density of the prose, which provides a rigorous examination of state-level decision-making during the early 20th century.
