At about this same time, the barons began to argue with the Habsburgs over who would inherit the lands of the now-extinct Kyburg family.

In 1267, the disputes led to war between the barons and the combined Zurich and Habsburg forces.

The Habsburgs established an Amt Regensberg, with a Habsburg-appointed Schultheiß leading the town council.

Stone blocks and two bells from the abbey were brought by ox cart to the church at Regensberg to rebuild it.

Following the collapse of the Swiss Ancien Régime in 1798, Regensburg became part of the district of Bülach.

Eberhard II was born in Regensberg around 1170 and died in Friesach, Austria, on 30 November 1246.

He was excommunicated in 1245 after refusing to publish a decree deposing the emperor and died suddenly the next year.
