Who was the first Russian King of Poland, whose Adjutant General was Pavel Alexandrovich Stroganov?
Alexander I of Russia Alexander I (Russian: Александр Павлович , Aleksandr Pavlovich; 23 December [O.S. 12 December] 1777 – 1 December [O.S. 19 November] 1825 ) reigned as Emperor of Russia from 23 March 1801 to 1 December 1825. He was the son of Paul I and Sophie Dorothea of Württemberg. Alexander was the first Russian King of Poland, reigning from 1815 to 1825, as well as the first Russian Grand Duke of Finland. He was sometimes called Alexander the Blessed.
Peter the Great Peter the Great (Russian: Пётр Вели́кий , "Pyotr Velikiy"; ] ), Peter I (Russian: Пётр I , "Pyotr I"; ] ) or Peter Alexeyevich (Russian: Пётр Алексе́евич ; ] ; 9 June [O.S. 30 May] 1672  – 8 February [O.S. 28 January] 1725 ) ruled the Tsardom of Russia and later the Russian Empire from 7 May (O.S. 27 April) 1682 until his death, jointly ruling before 1696 with his elder half-brother, Ivan V. Through a number of successful wars he expanded the Tsardom into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, westernized, and based on The Enlightenment. Peter's reforms made a lasting impact on Russia and many institutions of Russian government trace their origins to his reign.
