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.
Charles Whitworth, 1st Earl Whitworth
Irritated by his failure to stun him by a display of violence (such as that which had so daunted the Venetian plenipotentiaries before the treaty of Campo Formio), Napoleon did not hesitate to suggest in one of his journals that Whitworth had been privy to the murder of Paul I in Russia. At St. Helena in July 1817 he alluded to him with calmness as ""habile"" and ""adroit"", but he always maintained that the accepted version of the celebrated interview of 13 March was ""plein des faussetés"".
