Paul I of Russia
Paul I (; "Pavel Petrovich") ( – ) reigned as Emperor of Russia between 1796 and 1801. Officially, he was the only son of Peter III and Catherine the Great, though Catherine hinted that he was fathered by her lover Sergei Saltykov, who also had Romanov blood, being a descendant of the first Romanov tsar's sister, Tatiana Feodorovna Romanova.
Assassination
In the modern world, the killing of important people began to become more than a tool in power struggles between rulers themselves and was also used for political symbolism, such as in the propaganda of the deed. In Russia alone, two emperors, Paul I and his grandson Alexander II, were assassinated within 80 years. In the United Kingdom, only one Prime Minister has ever been assassinated—Spencer Perceval on May 11, 1812.
