[3] The resulting treaty, signed at Hautcret Abbey on 19 October 1211, forced Berthold to accept Savoyard suzerainty over the upper Valais.

[4] However, when he discovered that a majority had elected the Hohenstaufen Philip of Swabia (antiking to Welf Emperor Otto IV of Brunswick) he renounced his claim.

In exchange for this renunciation, Berthold gained territorial concessions in what is now southern Germany and northern Switzerland, consolidating Zähringer hold over the Ortenau, the Breisgau, Schaffhausen, Breisach and All Saints' Abbey.

His nephew Konrad von Urach who would eventually decline the papacy was put under the tutelage of Berthold's uncle.

The Zähringer lands partly reverted to the crown, were granted imperial immediacy, or were divided between the houses of Urach (the counts of Freiburg), Kyburg and Fürstenberg.
