This study investigates the internal bureaucratic structure and diplomatic decision-making processes of the French Foreign Ministry, the Quai d'Orsay, during the critical period leading to the First World War. M. B. Hayne utilizes extensive archival research to examine the interplay between political leadership and the career civil servants who shaped French foreign policy. By focusing on the personnel, prejudices, and administrative machinery of the ministry, the author provides a detailed analysis of how institutional culture influenced France's actions during the July Crisis. The work argues that understanding the internal dynamics of the Quai d'Orsay is essential for a comprehensive grasp of the origins of the Great War.

Historians and scholars of early 20th-century diplomacy identify this work as a foundational text for understanding the administrative history of the French government. Readers frequently note the academic density of the prose and the depth of the archival research presented by the author.
