The Oberpräsident represented the Prussian government in the province, and was busy with implementing and supervising central prerogatives of the Prussian government. The provinces of Prussia were further subdivided into government districts (Regierungsbezirke), subject to the High Commissioner. As to self-rule each province also had a provincial diet (Provinziallandtag in German), the members of which were elected in indirect election by county councillors and city councillors of the constituent rural counties and independent cities.
