2017 marked the 150th anniversary of an unprecedented event in Russian history: the government of the Russian Empire sold for a symbolic amount a huge territory rich in natural fossils - Alaska. The outpost of Russia in the Pacific Ocean was surrendered to America by order of Tsar Liberator Alexander II. How were the vast territories of Russian America dismembered and swept in the 19th century? Who is guilty of rejecting Alaska from Russia? Analyzing archival sources, the author of the book Ivan Mironov comes to the conclusion: the sale of Alaska in 1867 was nothing more than a betrayal of Russia's interests. The political situation of that time had no reason to surrender overseas possessions.
