 Lenin was concerned by the survival of the Tsarist bureaucratic system in Soviet Russia, particularly during his final years.Condemning bureaucratic attitudes, he suggested a total overhaul to deal with such problems, in one letter complaining that "we are being sucked into a foul bureaucratic swamp".During December 1922 and January 1923 Lenin dictated "Lenin's Testament", in which he discussed the personal qualities of his comrades, particularly Trotsky and Stalin.
