In October and November 1918, Austria-Hungary disintegrated, and on its ruins, new independent states emerged, formed by the nations that had previously been part of the Dual Monarchy. One of the causes of its collapse was defeat on the battlefields of the First World War, accompanied by revolutionary tendencies among its constituent peoples. On 1 November 1918, Ukrainian politicians and military leaders in Lviv proclaimed the Ukrainian state, later known as the West Ukrainian People’s Republic. Its armed forces, which came to be known as the Galician Army, began to form. Among their ranks were many former soldiers of non-Ukrainian origin, including Czechs. This article analyses the reasons for the presence of Czechs in the Western Ukrainian army, the legal basis for their recruitment, and the military careers of selected officers.
