Eccentric and despotic, Grand Duke Konstantin Pavlovich (1779-1831) did not at all look like the heir to the Russian throne. The son of Emperor Paul I, who was killed by the conspirators, and the brother of Alexander I, he dreamed of leading the life of a private person and renounced the imperial crown even when all of Russia swore allegiance to him. What this led to is known. The rebels on Senate Square shouted “Hurray!” Constantine and... the Constitution (seemingly considering the latter to be the wife of the Grand Duke). Then there was an uprising in Poland, in which Konstantin Pavlovich also played a not very enviable role. The life of one of the most eccentric representatives of the House of Romanov is vividly and fascinatingly described in the book presented to the attention of readers. The second edition of the book has been significantly revised by the author.
