Duchy of Swabia
The name is ultimately derived from the medieval Duchy of Swabia, one of the German stem duchies, representing the territory of Alemannia, whose inhabitants were interchangeably called "Alemanni" or "Suebi". This territory would include all of the Alemannic German areal, but the modern concept of Swabia is more restricted, due to the collapse of the duchy of Swabia in the 13th century. Swabia as understood in modern ethnography roughly coincides with the Swabian Circle of the Holy Roman Empire as it stood during the Early Modern period.
