2. Francois Ravaillac
Francois Ravaillac was an assassin who assassinated Henri IV of France. Of course, he has to get most severe treatment as possible for his deeds. He was tortured for days to get the names of his fellow assassins and the conspirators behind this assassination plot, but he denied that he had any co-conspirators and insisted that he acted alone.
On the day of May 27, finally, he was tortured one last time at the Place de Grève in Paris before being pulled apart by four horses. Before his execution, Ravaillac’s right arm was dived into blazing sulfur and pliers were used to forcefully pull skin from his chest, thighs and arms. Liquid metals and boiling oil were then poured into these injuries and everywhere on his body. At last, he was tied to four horses and had his body torn separated.
