Délvidék
Délvidék is a historical political term referring to varying areas in the southern part of what was the Kingdom of Hungary. In present-day usage, it often refers to the Vojvodina region of Serbia.
In the Middle Ages, like the names Alvidék and Végvidék, Délvidék referred to the Hungarian counties and vassal banates beyond the Danube and the Sava.
By the 18th and 19th centuries, Délvidék referred only to Bácska and Banat. After the 1920 dismemberment of Hungary, the meaning was further narrowed to only those areas of the former Kingdom of Hungary attached to the newly formed Yugoslav state. In the Second World War, the Yugoslav areas occupied and annexed by Hungary were in some Hungarian sources called "az anyaországhoz visszatért délvidéki területek". Banat, divided between Romania and German-occupied Serbia was no longer considered part of the concept.
In contemporary usage, Délvidék has several uses. It can refer to the imprecisely defined area of Serbia's northern Pannonian Basin including Vojvodina, the Belgrade region, and the Mačva plain as well as eastern Croatia. Sometimes the term is used in the narrow sense of Vojvodina, although it has largely been replaced by Vajdaság, the Hungarian name for Vojvodina. "Délvidék Hungarians" can refer to Hungarians in Vojvodina or, in a larger sense, to both the Vojvodina Hungarians and Hungarians of Croatia.
