Posthumous execution

Posthumous execution is the ritual or ceremonial execution of an already dead body. Formerly, many Christians believed that the resurrection of the dead on judgement day required that the corpse be whole so that the person would rise facing God. If dismemberment stopped the possibility of resurrection, then a posthumous execution was an effective way of punishing a criminal.

Examples

A number of the regicides of Charles I of England had died before the Restoration of King Charles II. Parliament passed an order of attainder for High Treason on the four most prominent deceased regicides: John Bradshaw the court president, Oliver Cromwell, Henry Ireton and Thomas Pride. The bodies were exhumed and the first three were hanged, drawn and quartered at Tyburn. The most prominent was the former Lord Protector Cromwell, whose body - after said "punishment" - was thrown, minus its head, into a common pit. The head was finally buried in 1960. The body of Pride was not "punished" perhaps because it had decayed too much. Of the regicides still alive then, some were executed and others either fled or were imprisoned. For a full list see List of regicides of Charles I.
In 1917 the body of Rasputin, the Russian monk, was exhumed from the ground by a mob and burned with gasoline.
