County of Mark
In many Lower Rhenish and Westphalian and Lower Saxon estates of the Holy Roman Empire the term Landdrost or Drost(e) described the chief executive official of a military, jurisdictional and/or police ambit, representing his lord-paramount of the territory, therefore often appearing with the affix 'land-'. Among the many territories using the term were the Prince-Archbishopric of Bremen, the Prince-Bishopric of Hildesheim, the County of Mark, and the Duchy of Mecklenburg.
