The Danube Swabians is a collective term for the ethnic German-speaking population who lived in Kingdom of Hungary of east-central Europe, especially in the Danube River valley, first in the 12th century, and in greater numbers in the 17th and 18th centuries. Most were descended from earlier 18th-century Swabian settlers from Upper Swabia, the Swabian Jura, northern Lake Constance, the upper Danube, the Swabian-Franconian Forest, the Southern Black Forest and the Principality of Fürstenberg, followed by Hessians, Bavarians, Franconians and Lorrainers recruited by Austria to repopulate the area and restore agriculture after the expulsion of the Ottoman Empire. They were able to keep their language and religion and initially developed strongly German communities in the region with German folklore.

The Banat Swabians are an ethnic German population in the former Kingdom of Hungary in Central-Southeast Europe, part of the Danube Swabians and Germans of Romania. They emigrated in the 18th century to what was then the Austrian Empire's Banat of Temeswar province, later included in the Habsburg Kingdom of Hungary, a province which had been left sparsely populated by the wars with the Ottoman Empire. At the end of World War I in 1918, the Swabian minority worked to establish an independent multi-ethnic Banat Republic; however, the province was divided by the Treaty of Versailles of 1919, and the Treaty of Trianon of 1920. The greater part was annexed by Romania, a smaller part by the Kingdom of Serbs, Croats and Slovenes and a small region around Szeged remained part of Hungary.
