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.
Armand-Emmanuel de Vignerot du Plessis, Duc de Richelieu
In the Russian army, he achieved the rank of Major General but later resigned his commission after what he considered an unwarranted reprimand by Catherine's successor, Czar Paul I. His prospects brightened, however, after Paul was murdered in 1801. The new Russian emperor, Czar Alexander I, was one of his friends. The erasure of Richelieu's name from the list of prohibited "émigrés" who could not legally return to France, which Richelieu on his own had previously been unable to secure from Napoleon Bonaparte, was accorded on the request of Alexander's new imperial government, and in 1803 Alexander appointed him Governor of Odessa. Two years later, he became Governor-General of a large swathe of land recently conquered from the Ottoman Empire and called "New Russia", which included the territories of Chersonese, Ekaterinoslav and the Crimea. In the eleven years of his administration, Odessa greatly increased in size and importance, eventually becoming the third largest city in the empire by population. The grateful Odessites erected a bronze monument to him in 1828. These are the famous Odessa Steps, crowned by a statue of Richelieu. He commanded a division in the Turkish War of 1806–1807, and was engaged in frequent expeditions to the Caucasus.
