Sergei Petrovich Troubetzkoy

Prince Sergei Petrovich Trubetskoy (; 29 August 1790 – 22 November 1860) was one of the organizers of the Decembrist movement. Close to Nikita Mikhailovich Muravyov in his views, he was declared the group's leader on the eve of the December 26 uprising in 1825 but failed to appear, and instead sought refuge in the Austrian embassy. Early years Trubetskoy was born in the noble Trubetskoy family. His father was Prince Pyotr Sergeyevich Troubetzkoy (1760–1817). His mother, Daria (d. 1796), was a daughter of the Georgian prince Alexander Bakarovich Gruzinsky. Troubetzkoy received home education, in 1806 he started attending lectures at Moscow University. In 1808 he entered Leib Guards Semyonovsky regiment. As a soldier, he participated in all significant battles of the Sixth Coalition campaign in 1812-1814 including the Battle of Borodino, the Battle of Maloyaroslavets, the Battle of Lützen, the battle of Bautzen, and the Battle of Kulm, and received many orders. In the Battle of Leipzig he was badly wounded. After the war, he continued military service and in 1821 he was promoted to colonel. Decembrists After the war Trubetskoy became a Freemason, a member of the Lodge of the Three Virtues. He was among the founders of the first proto-Decembrists societies - the Union of Salvation (1816) and later the Union of Prosperity (1819). The two unions were largely based on freemasonry. They sought gradual improvement of the Russian Empire, but had not adopted some goals the Decembrists did later: complete abolition of serfdom, introduction of constitution and constitutionally secured liberties, abolition of privileges of upper estates of the realm. In 1819 Trubetskoy went abroad for treatment. When he returned in 1821 he found the Union had ceased to exist. Trubetskoy was one of the founders and leaders of the Northern Society. Trubestkoy advocated Constitutional monarchy, but other Decembrists desired revolution, to execute the tsar and establish a republic (e.g. Ryleev and Pestel). He was elected "dictator" but did not come to Senate Square, most probably because he expected the revolt to fail.
