Paul I of Russia
Paul I (; "Pavel Petrovich") ( – ) reigned as Emperor of Russia between 1796 and 1801. Officially, he was the only son of Peter III and Catherine the Great, though Catherine hinted that he was fathered by her lover Sergei Saltykov, who also had Romanov blood, being a descendant of the first Romanov tsar's sister, Tatiana Feodorovna Romanova.

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.
