Paul I of Russia
Paul remained overshadowed by his mother for most of his life. His reign lasted four years, ending with his assassination by conspirators. He adopted the laws of succession to the Russian throne—rules that lasted until the end of the Romanov dynasty and of the Russian Empire. He also intervened in the French Revolutionary Wars and, toward the end of his reign, added Kartli and Kakheti in Eastern Georgia into the empire which was confirmed by his son and successor Alexander I.
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"".
