TheLower Danube Circle orUnder Danube Circle[1] (German:Unterdonaukreis) was one of the administrative districts (German:Bezirke orRegierungsbezirke) of theKingdom of Bavaria between 1806 and 1837. It was named after its main river, theDanube and was the predecessor of the administrative district ofLower Bavaria (Regierungsbezirk Niederbayern). Its administrative headquarters were in Passau, but the appellate court was in Straubing.
The district was divided in the following judicial districts (Landgerichte), according to the original borders of the districts of the former territories (Herrschaftsgerichte):
In the years between 1806 and 1808 the Kingdom of Bavaria was divided into 15 'circles'. Their names were taken from their main rivers. TheUnterdonaukreis was initially composed of 10 rural divisions and, since 1809, of the independent city of Passau. In 1810, the Unterdonaukreis was enlarged. In another territorial reorganization initiated by KingLudwig I on 29 November 1837, the Unterdonaukreis again enlarged and renamedLower Bavaria (Niederbayern). District headquarters were moved from Passau to Landshut.
