The Duchy of Alsace was a large political subdivision of the Frankish Empire during the last decade 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 stabilize the southern reaches of Austrasia against Alemannia and Burgundy. By the late Middle Ages, the region was considered part of Swabia. The duchy was dissolved in 742 when a successor for the deceased Duke Liutfrid was not named. Liutfrid's descendants, the Counts of Nordgau and Sundgau, nevertheless continued as rulers of a substantial part of the former duchy.
The goal of this project is to resolve duplicates, standardize naming conventions, and ensure the quality of the profiles in the family tree of the Dukes of Alsace.
