Historical regions of Central Europe in the context of "Carniola"

Banat (UK: /ˈbænɪt, ˈbɑːn-/ BAN-it, BAHN-, US: /bəˈnɑːt, bɑː-/ bə-NAHT, bah-; Romanian: Banat; Hungarian: Bánság; Serbian: Банат, romanized: Banat) is a geographical and historical region located in the Pannonian or Carpathian Basin that straddles Central and Eastern Europe. It is divided among three countries: the eastern part lies in western Romania (the counties of Timiș, Caraș-Severin, Arad south of the Mureș river, and the western part of Mehedinți); the western part of Banat is in northeastern Serbia (mostly included in Vojvodina, except for a small part included in the Belgrade Region); and a small northern part lies within southeastern Hungary (Csongrád-Csanád County).

The region's historical ethnic diversity was severely affected by the events of World War II. Today, Banat is mostly populated by ethnic Romanians, Serbs and Hungarians, but small populations of other ethnic groups also live in the region. Nearly all are citizens of either Serbia, Romania or Hungary.

Prussia is a historical region in Central Europe on the south-eastern coast of the Baltic Sea that ranges from the Vistula delta in the west to the end of the Curonian Spit in the east and extends inland as far as Masuria, divided between Poland (Warmian–Masurian Voivodeship), Russia (Kaliningrad Oblast) and Lithuania (Lithuania Minor). This region is often also referred to as Old Prussia.

Tacitus's Germania (98 AD) is the oldest known record of an eyewitness account on the territory and its inhabitants. Suiones, Sitones, Goths and other Germanic people had temporarily settled to the east and west of the Vistula River during the Migration Period, adjacent to the Aesti, who lived further to the east.
