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.
Paul I of Russia
Catherine suffered a stroke on 17 November 1796, and died without regaining consciousness. Paul's first act as Emperor was to inquire about and, if possible, destroy her testament, as he feared it would exclude him from succession and leave the throne to Alexander. These fears may have contributed to Paul's promulgation of the Pauline Laws, which established the strict principle of primogeniture in the House of Romanov, leaving the throne to the next male heir.
