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.
Tadeusz Kościuszko
The death of Tsaritsa Catherine the Great on November 17, 1796, led to a change in Russia's policies toward Poland. On November 28, Tsar Paul I, who had hated Catherine, pardoned Kościuszko and set him free, after he had tendered an oath of loyalty. Paul promised to free all Polish political prisoners held in Russian prisons and forcibly settled in Siberia. The Tsar gave Kościuszko 12,000 rubles, which the Pole later, in 1798, attempted to return, when also renouncing the oath.
