Rasputinism 

To be killed in a protracted, almost ridiculous way.

Derives from the case of Grigori Rasputin who was poisoned with cyanide, shot at least twice and then thrown in the River Neva. He was then dug up by Bolsheviks and his remains set on fire.

The posthumous execution of Benito Mussolini in 1945 and Oliver Cromwell in 1660 was classic Rasputinism.
