Flighty and eccentric, 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, refused 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... Constitutions (it seems, considering the latter the wife of the Grand Duke). Then there was an uprising in Poland, in which Konstantin Pavlovich also played a not too enviable role. The life of one of the most peculiar representatives of the Romanov dynasty is vividly and fascinatingly described in a book presented to the attention of readers.
