Alexander I of Russia (Russian: Александр I Павлович, Aleksandr I Pavlovich) (23 December [O.S. 12 December] 1777 – 1 December [O.S. 19 November] 1825), also known as Alexander the Blessed (Russian: Александр Благословенный, Aleksandr Blagoslovennyi) served as Emperor of Russia from 23 March 1801 to 1 December 1825 and Ruler of Poland from 1815 to 1825, as well as the first Russian Grand Duke of Finland and Lithuania.
He was born in Saint Petersburg to Grand Duke Paul Petrovich, later Emperor Paul I, and Maria Feodorovna, daughter of the Duke of Württemberg. Alexander was the eldest of four brothers. He succeeded to the throne after his father was murdered, and ruled Russia during the chaotic period of the Napoleonic Wars. In the first half of his reign Alexander tried to introduce liberal reforms, while in the second half he turned to a much more arbitrary manner of conduct, which led to the revoking of many early reforms. In foreign policy Alexander gained certain successes, mainly by winning several military campaigns. In particular under his rule Russia acquired Finland and part of Poland. The strange contradictions of his character make Alexander one of the most interesting Tsars. Adding to this, his death was shrouded in mystery, and the location of his body remains unknown.
