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.
History of Europe
The era of the French Revolution and the subsequent Napoleonic wars was a difficult time for monarchs. Tsar Paul I of Russia was assassinated; King Louis XVI of France was executed, as was his queen Marie Antoinette. Furthermore, kings Charles IV of Spain, Ferdinand VII of Spain and Gustav IV Adolf of Sweden were deposed as were ultimately the Emperor Napoleon and all of the relatives he had installed on various European thrones. King Frederick William III of Prussia and Emperor Francis II of Austria barely clung to their thrones. King George III of England lost the better part of his empire.
