Military Frontier
There was also an emigration of Serbs from the eastern parts of the region, which belonged to Military Frontier until 1751. After the abolishment of the Theiß-Maros section of Military Frontier, many Serbs emigrated from north-eastern parts of Batschka. They moved either to Russia (notably to New Serbia and Slavo-Serbia) or to Banat, where Military Frontier was still needed.
