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.

The Transylvanian Saxons are a people of mainly German ethnicity and overall Germanic origin —mostly Luxembourgish and from the Low Countries initially during the medieval Ostsiedlung process, then also from other parts of present-day Germany— who settled in Transylvania in various waves, starting from the mid and mid-late 12th century until the mid 19th century.
