Königsbann, literally king's ban (, more rarely bannum, from the OHG: ban), was the exercise of royal jurisdiction in the Holy Roman Empire.
A specific ban (German: Bann) identified: the actual order or prohibition the penalties for contravening the ban the region to which the ban applied
The king's ban in the legal history of the Holy Roman Empire was divided into several distinct types depending on their function: Heerbann, the right to raise an army, Blutbann (blood courts; high jurisdiction which included capital punishment), Friedensbann (special royal protection of people and property), Verordnungsbann (the authority to decide legal standards) and Verwaltungsbann (the force to be used).
The king used a so-called Bannleihe ("ban investiture") to transfer (invest) the ban, especially the Blutbann, to counts or advocates to exercise.
