Timeline of Polish history The Galician Socialist Soviet Republic[a] was a short-lived, self-declared Bolshevik political entity that existed from 15 July to formally 21 September 1920 with the capital in the city of Tarnopol (Ternopil).

A similar, but less elaborate activity, of the communist Polrevkom, was related to the North-Western front of the Red Army (the "government" was seated in Białystok).

The Galician Socialist Soviet Republic was severely understaffed, and while released Ukrainian memoirs leave the fate of the erstwhile ZUNR officials unknown, many do mention that local educated Ukrainians worked for the Soviet administration, being afraid of what letting Poles and Jews dominating every administrative ministry would entail.

Bolshevik reports claim that the Western Ukrainian population supported them out of their hatred for Petlura, whose alliance with Poland was seen as betrayal of the Galician state.

Borys Kolodii, a clerk in the War Commissariat, described how every official would assign positions to their co-nationals and then impose either Polish or Ukrainian as the de facto office language.
