The book contains a consistent analysis of the ideas of P.I. Pestel, the evolution of his views from constitutional-monarchical to republican, consistent democracy, the proclamation of equality of citizens before the law, the destruction of estates, the rejection of electoral qualifications, the division of lands into private and public. "Russian Truth," like the Decembrist movement as a whole, has a solid tradition of study. Turning to the history of research and publication of Pestel's project, you can often find that in some respects this historiography itself is more significant and fascinating than the subject itself, which was in the focus of its consideration.
