The Amtmann or Ammann (in Switzerland) was an official in German-speaking countries of Europe and in some of the Nordic countries from the time of the Middle Ages whose office was akin to that of a bailiff. He was the most senior retainer (Dienstmann) of an Amt; the administrative office of a territorial lord (Landesherr) created to manage the estates of manors (Gutshöfe), castles and villages. The estates were both administrative as well as juridical districts. The Amtmann was usually a member of the nobility or a cleric. In towns, he was also often a member of the wealthy classes amongst the citizenship. He resided in an Amthaus or Amtshaus and collected taxes from the district (Amtsbezirk), administered justice and maintained law and order with a small, armed unit.
Later, the word Beamter superseded the older word Amtmann and has come to mean "official" or "civil servant". The word Amtmann is derived from ambet-ambachtos - "one sent round", Celtic: Latin ambactus "envoy", "herold", "servant", French, ambassadeur, "ambassador". By contrast, the Icelandic word ambátt, "female slave" and the Norwegian ambått "room maid", "maiden", emerged from the Celtic-Latin via Old German/Old Nordic.
In Holstein during the Danish era (to 1864) the Amtmann was the senior official of a sovereign department (landesherrliches Amt). As head of the administration he was subordinate from 1546 to the ministry (German Chancellery) in Copenhagen. The Amtmann was also a secular judge of the trial court (erster Instanz) and, together with the Propst or provost, made up the ecclesiastical court or consistory (Konsistorium). In a literary testimony to the office, Detlev von Liliencron wrote a ballad called "Pidder Lüng" in which there is an Amtmann of Tønder, called Henning Pogwisch.
