After the demise of the von Staufens, both abbey and town came under the control of Württemberg, a State of the Holy Roman Empire.

During the Reformation, Adelberg became a Klosteramt (an administrative division centering on the estates of a dissolved monastery), consisting of the former Abbey and the village of Hundsholz.

The school in Adelberg served this purpose until 1648, its most famous pupil being mathematician and astronomer Johannes Kepler (1584–1586).

The monastery was itself established in 1178 by the Premonstratensian canons of Roggenburg Abbey, and it came under the direct protection of Frederick I, Holy Roman Emperor by a charter of 1181.

Abensberg and the neighbouring municipalities of Birenbach, Börtlingen und Rechberghausen form the Gemeindeverwaltungsverband (joint administrative union) of Eastern Schurwald.

A Gemeindeverwaltungsverband (GVV) is a voluntary association of municipalities within the same administrative district which pool their resources and public services in order to save money.

The Mayor of Adelberg is Wolf-Dieter Hermann, who will be succeeded in June 2010 by Carmen Marquardt, who won 60.7% of the vote in the election on 15 March 2010.
