Oberwart is a town in Burgenland in southeast Austria on the banks of the Pinka River, and the capital of the district of the same name. With almost 8,000 inhabitants it’s the third largest town in Burgenland, after Eisenstadt and Neusiedl am See. Oberwart is the cultural capital of the small ethnic Hungarian minority in Burgenland, living in the Upper Őrség or Wart microregion.

Lajtabánság, or the Banate of Leitha, was a short-lived western Hungarian state in the region where the Austrian federal state of Burgenland now exists. It existed between 4 October and 10 November 1921, following the Treaty of Trianon and the departure of the rump Kingdom of Hungary's army and after the Sopron plebiscite was held in the area according to the Venice protocol.
