The Strandzha Commune also known as the Strandzha Republic was a short-lived anarchist commune in East Thrace. It was proclaimed during the Preobrazhenie Uprising in 1903. In the mountains of Strandzha, IMARO insurgents began preparations for their uprising and the local Thracian peasantry began spontaneously establishing a libertarian communist system in the region. Once the uprising was initiated and insurgents captured much of the region, the Strandzha Commune was proclaimed, definitively establishing communism in the areas liberated from Ottoman control. The Commune would last about a month before its suppression by the Ottoman Empire, during which thousands were killed or became refugees.

When I visited Brașov two years ago, I checked out the "Tales of Communism Museum" and saw these flags!
