Description:
In Britain, death by hanging was the principal form of execution from Anglo-Saxon times until capital punishment was abolished in 1964. Up to May 1868 all hangings were carried out in public and attracted large crowds who were at least supposed to be deterred by the spectacle, but who more probably went for the morbid excitement and the carnival atmosphere that usually surrounded such events.
