In 1490, due to increased oppression of Ukrainians at the hands of the Polish, a series of successful rebellions was led by Ukrainian hero Petro Mukha, joined by other Ukrainians, such as early Cossacks and Hutsuls, in addition to Moldavians (Romanians). Known as Mukha's Rebellion, this series of battles was supported by the Moldavian prince Stephen the Great, and it is one of the earliest known uprisings of Ukrainians against Polish oppression. These rebellions saw the capture of several cities of Pokuttya, and reached as far west as Lviv, but without capturing the latter.
