This work investigates the global dimensions of the First World War by examining how imperial ambitions and colonial structures shaped the conflict's origins, conduct, and ultimate resolution. John H. Morrow Jr., a distinguished historian of military and aviation history, utilizes a vast array of primary sources and diplomatic records to argue that the war was fundamentally a struggle for imperial hegemony. He frames the conflict not merely as a European dispute, but as a systemic collapse of global power structures that had been building for decades. The analysis provides a comprehensive framework for understanding the interplay between domestic political pressures and international military strategy.
