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.
Alexander I of Russia
Alexander I (, Aleksandr Pavlovich; – ) reigned as Emperor of Russia between 1801 and 1825. He was the oldest son of Paul I and Sophie Dorothea of Württemberg. Alexander was the first Russian King of partitioned Poland, reigning from 1815 to 1825, as well as the first Russian Grand Duke of Finland, reigning from 1809 to 1825.
