Imperial Ban

The imperial ban (German: Reichsacht) was a form of outlawry in the Holy Roman Empire. At different times, it could be declared by the Holy Roman Emperor, by courts like the Vehmgericht or the Reichskammergericht, or by the Reichstag.

People under imperial ban, known as Geächtete (from about the 17th century, colloquially also as Vogelfreie, lit. "free as a bird"), lost all their rights and possessions. They were legally considered dead and anyone was allowed to rob, injure or kill them without legal consequences. The imperial ban automatically followed the excommunication of a person, as well as extending to anyone offering help to a person under the imperial ban.

Those banned could reverse the ban by submitting to the legal authority. The Aberacht, a stronger version of the imperial ban, could not be reversed.

The imperial ban was sometimes imposed on whole Imperial Estates. In that case, other estates could attack and possibly conquer them. For the banned state that meant that they would lose their Reichsunmittelbarkeit and in the future have a second overlord in addition to the emperor.

Famous people under the imperial ban included:

• 1180 Henry the Lion for refusing military support to Frederick I, Holy Roman Emperor, against the cities of the Lombard League.
• 1225 Count Frederick of Isenberg for killing his uncle Engelbert II of Berg, Archbishop of Cologne.
• 1235 King Henry (VII) of Germany for the rebellion against his father Emperor Frederick II.
