Plan Z: The Popular Front, Civil-Military Relations and the French Army’s Plan to Defeat a Second Paris Commune, 1934–1936

Following the formation of the Popular Front in 1934, French generals feared that the alliance, which included the French Communist Party (pcf), could foreshadow a coming revolt in Paris. Generals Maxime Weygand and Maurice Gamelin responded by preparing to implement Plan Z, a plan to defeat a Parisian revolt. Given politicians’ fear that many French officers were antirepublican, the French Army would have faced a major political crisis if Plan Z had leaked. Plan Z called for a multidivisional assault on Paris, which showed that the General Staff believed a large-scale revolution was possible. Understanding the development of Plan Z adds to scholars’ recognition of French officers’ long-term fear of communism and mistrust of civilians. It reveals that senior officers were more politicized and afraid of civilians than most scholars have realized and helps explain the military’s central role in betraying the Third Republic and creating the Vichy Regime in 1940.
