Rotenburg may refer to:
Rotenburg is a district (Landkreis) in Lower Saxony, Germany. It is bounded by (from the north and clockwise) the districts of Stade, Harburg, Heidekreis, Verden, Osterholz and Cuxhaven.
In medieval times the region was part of the bishoprics of Bremen and Verden. After the Protestant Reformation the bishoprics became secular principalities, colloquially called Bremen-Verden, and finally parts of the Kingdom of Hanover.
The present district was established in 1977 by merging the former districts of Rotenburg and Bremervörde.
The Wümme River runs through the district from east to west. The marshy area to both sides of the river is called the Wümmeniederung (Wümme Depression).
The coat of arms displays:
Rotenburg an der Wümme (until May 1969: Rotenburg in Hannover) is a town in Lower Saxony, Germany. It is the capital of the district of Rotenburg.
Rotenburg is situated at the Wümme river, which in turn lies between the rivers Elbe and Weser at about the same latitude as Hamburg and Bremen, the latter lying 40 km to the west. It is often called "Rotenburg (Wümme)" in order to distinguish it from the town Rotenburg an der Fulda in Hesse and Rothenburg ob der Tauber in Bavaria.
The town was founded in 1195, when the Prince-Bishop Rudolf I of Verden built a castle at the place. Then the town belonged to the Prince-Bishopric of Verden, established in 1180. The castle took its name from the colour of the bricks (rot means "red", Burg "castle"). The adjoining settlement remained a tiny village until the 19th century.
In 1648 the Prince-Bishopric was transformed into the Principality of Verden, which was first ruled in personal union by the Swedish Crown - interrupted by a Danish occupation (1712–1715) - and from 1715 on by the Hanoverian Crown.
