The Polish–Ukrainian War was fought over the city of Lviv and the region of Eastern Galicia, which both Poles and Ukrainians claimed after the collapse of Austria-Hungary. Ukrainian forces took control of Lviv and proclaimed the West Ukrainian People's Republic, but the city, where Poles formed a majority, was contested in street fighting and recaptured by Polish troops. The conflict continued across the countryside, with the Ukrainian Galician Army at first holding its ground. Poland, better supplied and helped by the Haller Army, which had been formed in France, drove the Ukrainians out by the summer of 1919. The Allies later recognized Polish control of the region, and the dispute left deep resentment between the two peoples.
