It was in this reign that an important change in the government of the Danubian Principalities was introduced: previously, the Porte had appointed Hospodars, usually native Moldavian and Wallachian boyars, to administer those provinces; after the Russian campaign of 1711, during which Peter the Great found an ally in Moldavia Prince Dimitrie Cantemir, the Porte began overtly deputizing Phanariote Greeks in that region, and extended the system to Wallachia after Prince Stefan Cantacuzino established links with Eugene of Savoy. The Phanariotes constituted a kind of "Dhimmi" nobility, which supplied the Porte with functionaries in many important departments of the state.
