Grand Duchess Сatherine (1788−1819), «Semigodness of Tver», the sister of Alexander I, played an outstanding role in the process of genesis of Russian conservatism as a political trend. She initiated a creation of Manifesto of Russian conservative thought — «The Memoir on Ancient and Modern Russia» by N.M.Karamzin. She proposed the leader of Russian conservative «Russian party» F.V.Rostopchin as a «dictator» of Moscow on the eve of the Patriotic war of 1812. Grand Duchess consequently fought against official liberalism of Alexander I. She was one of the personalities who managed to resign M.M.Speransky — the most important politician of official liberalism of that period.
