Duchy of Alsace

Former political subdivision of the Frankish kingdoms

The Duchy of Alsace was a large political subdivision of the Frankish Empire during the last century and a half of Merovingian rule. It corresponded to the territory of Alsace and was carved out of southern Austrasia in the last decade of the reign of Dagobert I, probably to stabilise the southern reaches of Austrasia against Alemannia and Burgundy. By the late Middle Ages, the region was considered part of Swabia.
