The article is devoted to the French intervention in Ukraine, which took place in autumn 1918 – spring 1919. The author considers the events in the Northern Black sea region, where the intervention took place, in the context of the Russian-Ukrainian realities of the revolutionary and civil war epoch, which mainly hindered the success of the intervention. The article demonstrates that the desire of the French leadership to be the organizer and guarantor of the post-war world order came into conflict with political tradition of France, the fatigue of the war and unexpected socio-political and military circumstances in the region.
