South of the Danube, a dialect of Dacian called "Daco-Moesian" was probably predominant in the region known to the Romans as Moesia, which was divided by them into the Roman provinces of Moesia Superior (roughly modern Serbia) and Moesia Inferior (modern northern Bulgaria as far as the Balkan range plus Roman Dobruja region). This is evidenced by the distribution of "-dava" placenames, which occur in the eastern half of Moesia Superior and all over Inferior. These regions were inhabited predominantly by tribes believed to have been Dacian-speaking, such as the Triballi, Moesi and Getae.
