Although the core religious vocabulary of the Romanian language originated from Latin, many terms were adopted from the Slavic Orthodoxy, showing a significant influence dating from the Bulgarian Empire (681–1396). Early modern period By 1541, the entire Balkan peninsula and northern Hungary became Ottoman provinces. Moldavia, Wallachia, and Transylvania came under Ottoman suzerainty but remained fully autonomous and until the 18th century, had some internal independence. However, some Romanian Cities (Dobruja, Constanta, Giurgiu, Turnu, Braila, Timișoara, Tighina, Catetea Alba and Basserabia) were completely under Ottoman control. During this period, the Romanian lands experienced a slow disappearance of the feudalism and the distinguishing of some rulers like Vasile Lupu and Dimitrie Cantemir in Moldavia, Matei Basarab and Constantin Brâncoveanu in Wallachia, and Gabriel Bethlen in Transylvania.
