An executioner, also known as a hangman or headsman, is an official who effects a sentence of capital punishment on a condemned person.
Common terms for executioners derived from forms of capital punishment—though they often also performed other physical punishments—include hangman (hanging) and headsman (beheading).
While this task can be occasional in nature, it can be carried out in the line of more general duty by an officer of the court, the police, prison staff, or even the military.
A special case is the tradition of the Roman fustuarium, continued in forms of running the gauntlet, where the culprit receives their punishment from the hands of the comrades gravely harmed by their crime, e.g. for failing in vital sentinel duty or stealing from a ship's limited food supply.
Many executioners were professional specialists who traveled a circuit or region performing their duty, because executions were rarely very numerous.
In medieval Europe, to the end of the early modern period, executioners were often knackers,[1] since pay from the rare executions was not enough to live off.
[4] In Alexandre Dumas' The Three Musketeers and in the film La veuve de Saint-Pierre (The Widow of Saint-Peter), minor character executioners are ostracized by the villagers.
In early modern German society, executioners and their families were considered "dishonourable people" (unehrliche Leute).
Unlike in France and many other European countries, far from being shunned, British executioners such as William Marwood, James Berry, Albert Pierrepoint, and Harry Allen were widely known and respected by the public.
