In 1235 part of the Hildesheim diocesan territory, the episcopal and capitular temporalities (Stift) were disentangled from the Duchy of Brunswick and Lunenburg and became an own territory of imperial immediacy called Prince-Bishopric of Brunswick and Lunenburg (German: Hochstift Hildesheim), a vassal of the Holy Roman Empire.
