In 1821, Greek nationalists headquartered in Odessa took control of Moldavia as the first step in a plan to extricate Greece from Ottoman domination. Phanariot rule in Walachia and Moldavia led the Greek nationalists to view the principalities as possible components of a renascent Byzantine Empire. The insurgency's leader, Alexander Ypsilanti, a general in the Russian army and son of a Phanariot prince, enjoyed the support of some Greek and Romanian boyars in the principalities; after more than a century of extortion, however, most Romanians resented the Phanariots and craved the end of Greek control. Tudor Vladimirescu, a peasant-born Romanian whose wits and military skill had elevated him to boyar rank, assumed power in Walachia in an anti-Phanariot national uprising directed at establishing a Romanian government under Ottoman suzerainty. Russia denounced both Ypsilanti and Vladimirescu. The two rebel leaders argued in Bucharest; afterwards, Greek officers shot the Romanian, mutilated his body, and dumped it into a pond, an act that also ended Romanian resistance, which evaporated after Vladimirescu's death. Then the Turks, with Russia's approval, attacked the principalities, scattered the Greek forces, and chased Ypsilanti into Transylvania. The Greek rebellion shocked the Porte, which no longer appointed Phanariot princes to the Walachian and Moldavian thrones and chose instead native Romanians.
