Bordesholm is a town in Schleswig-Holstein, Germany in the district Rendsburg-Eckernförde. Bordesholm is also the name of a former historical district of the Kingdom of Prussia and Weimar Republic for which it was the district capital. The district of Bordesholm was subsequently dissolved in 1932 and parceled out to neighboring districts (parts of the district of Bordesholm were joined with the district of Segeberg and the rest to Rendsburg-Eckernförde).
The town of Bordesholm developed around 1330, when the abbey of Neumünster (founded in 1127 by Bishop Vizelin) was moved to an island in the Bordesholm lake. Saint Vizelin was buried there. Thereafter, a village grew up at the shore of the lake, likely providing services to the abbey. Because of the abbey Bordesholm became the cultural and economic center of the duchy of Holstein (nowadays Schleswig-Holstein) region between Kiel and Neumünster.
During the reformation the abbey was closed in 1566 by duke Hans the Elder of Slesvig-Holsten-Haderslev. It then became a Latin school, which was dissolved in 1665. The remains of the abbey and school library became the foundation of the library of the newly founded University of Kiel. 1773-1865 the area of Bordesholm was administered by the King of Denmark by the virtue of his being Duke of Holstein.
Bordesholm is an Amt ("collective municipality") in the district of Rendsburg-Eckernförde, in Schleswig-Holstein, Germany. It is situated around the village Bordesholm, which is the seat of the Amt. It was called Bordesholm-Land until 30 June 2007.
