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.
Grand Duke Paul Alexandrovich of Russia
Grand Duke Paul was deeply affected by Alexandra's death. It took him a long time to overcome his depression. During this period, his brother Sergei and Sergei's wife took care of Paul's motherless children in a pattern of behavior that it would be repeated in the years to follow. In his widowhood, the grieving grand duke moved to Tsarskoye Selo, leaving his palace in St Peterburg that had been his home with Alexandra to never return. For a long time, the palace stood vacant. After that, the building changed many hands over time. When the revolution ended, the mansion was sold to the Russian Society for the Production of Equipment and Military Supplies. Eventually it became home to various Soviet institutions.
The palace has survived to the present and today it is at the disposal of Saint Petersburg State University.
