Duchy of Swabia
The name "Alamannia" was used by the 8th century, and from the 9th century, "Suebia" was occasionally used for "Alamannia", while "Alamannia" was increasingly used to refer to Alsace specifically. By the 12th century, "Suebia" rather than "Alamannia" was used consistently for the territory of the Duchy of Swabia.
