A Vogt (from the Old High German, also Voigt or Voight or Landvoigt or Fauth); plural Vögte; Dutch (land)voogd; Danish foged; Polish: wójt; ultimately from Latin vocatus) in the Holy Roman Empire was the German title of a reeve or advocate, an overlord (mostly of nobility) exerting guardianship or military protection as well as secular justice (Blutgericht) over a certain territory. The territory or area of responsibility of a Vogt is called a Vogtei (from vocatia).
