The government of the Western Ukrainian People's Republic, which was proclaimed on 19 October 1918, united with the Ukrainian People's Republic on 22 January 1919, although this was mostly a symbolic act because the western Ukrainians retained their own Ukrainian Galician Army and government structure.
