The Romanian minority in Bulgaria is concentrated in the northwestern part of the country, in Vidin Province, Vratsa Province and Pleven Province. They speak the Oltenian variety of the Romanian language. The Romanians from the Vidin Province are separated into 2 main groups: the "Dunăreni" (who live around the Danube river) and the "Pădureni" (who lived in the higher placed regions with many woods). In southwestern Bulgaria lives also a very small Aromanian population, such as in the village Peshtera. The territory where the Romanians from Bulgaria live never belonged to Romania and most of them declare themselves "vlasi" (= Vlachs) when asked in Bulgarian (e.g. on the census), though they use the self-designation "rumân" (= Rumanians) in their language. The Romanians in Bulgaria are not recognized as a national minority, but as en ethnic group and they don't enjoy ethnic rights in schools and churches since the Interwar period.
