Civilians led by Ante Ciliga Government of Italy Ante Ciliga (POW) Unknown The Proština rebellion was a rebellion by peasants in Istria, then a territory of the Kingdom of Italy, against the fascist government.

[2] In order to intimidate the population, fascist squadrons were intruding into Istrian villages.

The first such incursion to Krnica and Proština was undertaken on the night of 2–3 February 1921, the second in mid-March, and the third in early April of the same year.

During conflict in early April 1921, the Proština rebels managed to capture two fascists, while the other fascists retreated to Marčana and Krnica, taking with them the innkeeper Ivan Macuka as a hostage, whom the Proština rebels eventually freed.

After these events, units of the regular army and police with about 400 members, and with about 100 members of the fascist squadrons invaded the villages of Proština on 5 April 1921 and broke the resistance of the three hundred or so poorly armed peasants there.
