Regensburg#
Regensburg, town and diocese in Bavaria, centre of the Bavarian duchy from the 6th century on; played an important role in the formation and development of Austria. In July 976, the Babenberg Leopold I was appointed Margrave in Regensburg; in 979 Regensburg was given Wieselburg, where Bishop Wolfgang had a fortress built. Until 1803 the diocese held large estates in Lower Austria (Poechlarn, Ulmerfeld) ( Reichsdeputationshauptschluss). Regensburg was the location of the Permanent Imperial Diet, which was one of the reasons for the close contacts of the emperor and the Austrian princes with this town.
