With the 1382 treaty of Heimbach, the Bailiwick of Brandenburg, a member of the Priory of Germany, was granted a form of autonomy from the Sovereign Military Hospitaller Order of Saint John of Jerusalem of Rhodes and of Malta, which it was part of until then.
Today, the Bailiwick of Brandenburg of the Order of Saint John comprises about 3,300 Protestant Knights in 23 Associations or German Commanderies, as well as non-German Commanderies (Austria, Hungary, Finland, France and Switzerland).
Like their brothers in the Order of Malta, the Knights of the Bailiwick of Brandenburg of the Order of Saint John are active in Christian testimony and diaconal humanitarian aid to those who suffer.
Finally, in England, the Netherlands and Sweden, there are other Hospitaller Orders of Saint John that are autonomous and non-Catholic. They are associated with the Bailiwick of Brandenburg in the Alliance of the Orders of Saint John. These Orders of Saint John maintain close and cordial links with the Order of Malta, in particular in the context of working groups and regular exchanges on matters of mutual interest with those of the Alliance.
