During the Great War, mutiny challenged and sometimes overcame state authority. When the state remained strong, mutiny served to articulate and in some cases even affirm it. Mutiny could also demarcate the limits of the wartime state. The best-known mutiny in the armies of the British Empire took place in September 1917 at the training camp at Etaples in France. The French army mutinies of 1917 were more about consenting to the war than about rejecting it. In an agonised way, mutiny in France thus affirmed and articulated the mutineers' accountability to the wartime state, even as they challenged it. In Germany, mutiny both invoked the destruction of the Kaiserreich and seriously undermined the formation of the Weimar Republic. Mutiny became so successfully incorporated into state building in Kemalist Turkey that it ceased to be referred to as mutiny at all.
