In the history of Russian thought one can find many examples of persecution by the Tsarist government for ideological reasons, not only of philosophy but also of natural law. During three of them, repressive measures against the natural law professors and their works were taken which are the focus of this article. In the early nineteenth century Professor I. B. Schad, who gave a full course of philosophy and natural law, was removed from the University of Kharkov and from Russia for the commitment of Schelling’s philosophy, and his books were banned. In the 1820s A. P. Kunitsyn was removed from the teaching of natural law in Tsarskoye Selo Lyceum and the University of St.Petersburg. His book Natural Right was banned and withdrawn from sale. The famous conservative L. M. Magnitsky was an opponent of teaching of natural law at Kazan University and initiated a trial of professor of natural law G. I. Solntsev, dismissing him from the University. On his insistence, not only in Kazan, but also in other universities the teaching of natural law was forbidden in 1833. Refs. 10.
