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.
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.
