Alexander II of Russia (Russian: Александр II Николаевич, Aleksandr II Nikolaevich) (29 April [O.S. 17 April] 1818 in Moscow – 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Prince of Finland. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Александр Освободитель, Aleksandr Osvoboditel').
Born in Moscow, he was the eldest son of Nicholas I of Russia and Charlotte of Prussia, daughter of Frederick William III of Prussia and Louise of Mecklenburg-Strelitz. His early life gave little indication of his ultimate potential; until the time of his accession in 1855, aged 37, few imagined that he would be known to posterity as a leader able to implement the most challenging reforms undertaken in Russia since the reign of Peter the Great.
In the period of his life as heir apparent, the intellectual atmosphere of Saint Petersburg was unfavourable to any kind of change: freedom of thought and all forms of private initiative were being suppressed vigorously. Personal and official censorship was rife; criticism of the authorities was regarded as a serious offence. Some 26 years afterward, he had the opportunity of implementing changes; he would, however, be assassinated in public by the Narodnaya Volya (People's Will) terrorist organisation.
His education as a future emperor was carried out under the supervision of the liberal romantic poet and gifted translator Vasily Zhukovsky, grasping a smattering of a great many subjects and becoming familiar with the chief modern European languages. His alleged lack of interest in military affairs detected by later historians was his reflection on the results on his own family and on the effect on the whole country of the unsavoury Crimean War. Unusually for the time, the young Alexander was taken on a six-month tour of Russia, visiting 20 provinces in the country. He also visited many prominent Western European countries. As Tsarevich, Alexander became the first Romanov heir to visit Siberia.
Alexander II succeeded to the throne upon the death of his father in 1855. The first year of his reign was devoted to the prosecution of the Crimean War and, after the fall of Sevastopol, to negotiations for peace, led by his trusted counsellor Prince Gorchakov. The country had been exhausted and humiliated by the war. Bribe-taking, theft and corruption were everywhere. Encouraged by public opinion he began a period of radical reforms, including an attempt to not depend on a landed aristocracy controlling the poor, a move to developing Russia's natural resources and to reform all branches of the administration. In 1867 he sold Alaska to the United States for $7 million (equivalent to roughly $200 million in current dollars) after recognising the great difficulty of defending it against the United Kingdom or the former British colony of Canada.
