Shortly after the republic proclaimed independence from the Austro-Hungarian Empire a popular uprising took place in Lviv, where most residents were Polish and did not want to be part of a non-Polish state.
Kort tid efter, at republikken havde erklæret sig uafhængig fra Østrig-Ungarn, opstod der en folkelig opstand i Lviv, hvor det polske flertal ikke ønskede at høre under en fremmed stat.
