About seventy years later, with the death of Conradin in Naples in 1268, the line of the Hohenstaufen became extinct. Their former estates were confiscated as imperial property of the Holy Roman Empire. While the small town of Altdorf was ruled by the "Reichslandvogt" (imperial steward resp. bailiff) of Swabia, the abbey of Weingarten won the status of an "Imperial Abbey" with privileges similar to those of an Imperial Free City. The "Landvogtei" was given in 1473/1486 as pawn to Sigismund, Archduke of Austria, which led to its integration as a district within Further Austria.
