List of historical regions of Central Europe in the context of Serbian Bačka

Transylvania (Romanian: Transilvania [transilˈvani.a] or Ardeal; Hungarian: Erdély [ˈɛrdeːj]; German: Siebenbürgen [ˌziːbm̩ˈbʏrɡn̩] or Transsilvanien; Transylvanian Saxon: Siweberjen) is a historical and cultural region in Central Europe, encompassing central Romania. To the east and south its natural border are the Carpathian Mountains and to the west the Apuseni Mountains. Broader definitions of Transylvania also include the western and northwestern Romanian regions of Crișana and Maramureș, and occasionally Banat. Historical Transylvania also includes small parts of neighbouring Western Moldavia and even a small part of south-western neighbouring Bukovina to its north east (represented by Suceava County).

Transylvania is known for the scenery of its Carpathian landscape and its rich history, coupled with its multi-cultural character. It also contains Romania's second-largest city, Cluj-Napoca, and other very well preserved medieval iconic cities and towns such as Brașov, Sibiu, Târgu Mureș, Bistrița, Alba Iulia, Mediaș, and Sighișoara. It is also the home of some of Romania's UNESCO World Heritage Sites such as the Villages with fortified churches, the Historic Centre of Sighișoara, the Dacian Fortresses of the Orăștie Mountains and the Roșia Montană Mining Cultural Landscape.

Bačka (Serbian: Бачка, pronounced [bâːtʃkaː]) or Bácska (pronounced [ˈbaːtʃkɒ]), is a geographical and historical area within the Pannonian Plain bordered by the river Danube to the west and south, and by the river Tisza to the east. It is divided between Serbia and Hungary. Most of the area is located within the Vojvodina region in Serbia and Novi Sad, the administrative center of Vojvodina, lies on the border between Bačka and Syrmia. The smaller northern part of the geographical area is located within Bács-Kiskun County in Hungary.

Baranya or Baranja (Croatian: Baranja, pronounced [bǎraɲa]; Hungarian: Baranya, pronounced [ˈbɒrɒɲɒ]) is a geographical and historical region between the Danube and the Drava rivers located in the Pannonian Plain. Its territory is divided between Hungary and Croatia. In Hungary, the region is included in Baranya county, while in Croatia, it is part of Osijek-Baranja county.

Pomerelia, also known as Eastern Pomerania, Vistula Pomerania, and also before World War II as Polish Pomerania, is a historical sub-region of Pomerania on the southern shore of the Baltic Sea in northern Poland.

Gdańsk Pomerania is largely coextensive with Pomerelia, but slightly narrower, as it does not include Chełmno Land and Michałów Land.
