The State of Romania [Vl: România] is one of the nine constituent states of the Danubian Federation [Vl: Federația Dunărean], and the state with a population majority Vlach with minority Hungarian and German settlers. Divided into two provinces, the provinces of Transylvania [Vl: Transilvania] and Moldova [Vl: Moldavia], the history of the constituent provinces of Romania are ones of oppression by invaders. Held by the Hungarians, Russians, Turks and Austrians, the independent Vlach state never existed. However, since the revolution of 1848, the Vlach majority of Transylvania became free from foreign oppression. The Duchy of Moldova was incorporated into the State of Transylvania in 1859.
