"The medieval Principality of Moldavia emerged in the 1350s, and was the medieval precursor of modern Moldova and Romania. It reached prominence under rulers like Stephen the Great before becoming a vassal state of the Ottoman Empire from 1538, until the 19th century."

So 300-350 years of vassality towards Ottomans.

"A Greek presence had established itself in both Danubian Principalities of Moldavia and Wallachia, resulting in the appointment of Greek princes before the 18th century. After the Phanariot era, some Phanariot families in Wallachia and Moldavia identified themselves as Romanian in Romanian society (including the Rosetti family; C. A. Rosetti represented the radical, nationalist cause during and after the 1848 Wallachian revolution.)."

I didn't even start about the religious part which used the language of old slavonic coming from Bulgaria not Russia. Russia wasn't even Christian when we was because of Bulgaria/Byzantium. Old slavonic and after that turkish was the language of the nobles in these regions.

So was influenced by the Bulgaria then Byzantium then Ottoman empire in the history from 600-1800 but somehow 100 years of influence from Russia you think is more prominent.
