Nürnberger Burg
In 1105, Nuremberg Castle and the city became entangled in a dispute between Emperor Henry IV and his son Henry V. The city and castle were partially destroyed. In order to better protect the castle and city in the future, the emperor appointed Conrad I and his brother Gottfried II as Burgmann and made them responsible for the protection of the castle, making them burgraves. However, their official job title was Castellan; the title was first used by Gottfried III of Raabs.
