Danube
"Danube" is an Old European river name derived from a Proto-Indo-European "*dānu". Other river names from the same root include the Dunaj, Dzvina/Daugava, Don, Donets, Dnieper, Dniestr, Dysna, Tana and Tuoni. In Rigvedic Sanskrit, "dānu" means "fluid, drop", in Avestan, the same word means "river". In the Rigveda, "Dānu" once appears as the mother of Vrtra, "a dragon blocking the course of the rivers." The Finnish word for Danube is Tonava, which is most likely derived from the word for the river in Swedish and German, "Donau". Its Sámi name "Deatnu" means "Great River". It is possible that "dānu" in Scythian as in Avestan was a generic word for "river": "Dnieper" and "Dniestr", from "Danapris" and "Danastius", are presumed to continue Scythian "*dānu apara" "far river" and "*dānu nazdya-" "near river", respectively.
Danube Swabians
For the greater portion of their history, the Danube Swabian did not share a cultural identity. The term Swabian has its roots in the first wave a German-speaking immigrants from Swabia to re-settle southern Hungary after the expulsion of the Ottomans in 1689. However, it came to encompass all German-speaking people who followed in migrations from across the Holy Roman Empire in the eighteenth and nineteenth century. The term "Swabian" was not originally a self-proclaimed identity of a singular people but a term ascrided by Magyar lords to refer to German-speaking Catholic peasants, tavern keepers, and poor artisans. For the most part Swabians lived in villages, had few privileges, and no developed intellectual layer. In 1930 Hungary 55.4% of the total Swabian population were engaged in agriculture; 28.8% in industry, crafts, commerce, or transport; and 3.1% were in state administration. The rest were employed in the service sector.
