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.
Lithuania Governorate
After the third partition of the Polish–Lithuanian Commonwealth in 1795, the former territories of the Grand Duchy of Lithuania were divided between the Vilna Governorate and the Slonim Governorate by Catherine II of Russia. After her death just a year later, her son Paul I of Russia became the Emperor of Russia. He reversed or modified many of his mother's policies and decisions, including administrative divisions. On December 12, 1796, the two governorates were merged into one called the Litva Governorate with capital in Vilna. In 1801, Paul I was assassinated and the Litva Governorate was divided into the Litva-Vilna Governorate and the Litva-Grodno Governorate by his successor, Alexander I of Russia.
