 One of the early signs of change came just months after its suppression, when the Divan restored Târgoviște to its citizens, and the "cartel of the four [princely] families" was formally annulled.In July 1822, after having heard a new set of boyar complaints which had Russian and Austrian backing, the Sultan put an end to the Phanariote regime, appointing Grigore IV Ghica (the former "Caimacam" of 1821) and Ioan Sturdza as "native" Princes of Wallachia and Moldavia, respectively.Trying to appease Russia, in 1826 the Ottoman Empire also signed the Akkerman Convention, which set commercial freedoms for Wallachians and the Moldavians, and allowed the Divans to elect their Princes for seven-year terms.
