 The Romanian prime-minister at the time, Alexandru Marghiloman, was to admit however that the unification was decided in Romania, as the Moldavian leaders Daniel Ciugureanu and Ion Inculeț, aware of the widespread distrust of Romanian rule, feared an overt annexation would lead to a revolutionary situation.The 1812 Treaty of Bucharest between the Ottoman Empire and the Russian Empires provided for Russian annexation of the eastern part of the territory of the Principality of Moldavia, as well as the Turkish-ruled regions of Khotyn and Budjak (Southern Bessarabia).At first, the Russians used the name "Oblast of Moldova and Bessarabia", allowing a large degree of autonomy, but in 1828 Russia suspended the self-administration and called it the Governorate of Bessarabia, or simply Bessarabia.
