On 14 February 1764, Catherine II, convinced of the exceptional honesty of Prince Vyazemsky, appointed him
Prosecutor General of the
Senate. She personally wrote his "secret instruction", in which she clearly defined his responsibilities. The Empress reminded Alexander Vyazemsky that the Prosecutor General should be completely frank with the sovereign, since "in his position he is obliged to resist the strongest people", and this is only the imperial power "one of his support". She emphasized that she did not require "caress" from him, but "the only sincere treatment and firmness in business". Catherine II warned the Prosecutor General against getting involved in intrigues at court and suggested to have only "the only benefit of the fatherland and justice in mind, and take firm steps to take the shortest path to the truth". Alexander Vyazemsky, presumably, strictly adhered to the instructions given to him and enjoyed the full confidence of the empress, which allowed him not only to hold the highest prosecutor's post for almost 29 years, but also to significantly expand his powers. If at the beginning of his career he headed the Senate, and also oversaw the sale of salt and wine in the empire, then from the 1780s he already firmly held in his hands not only justice, but also finance and internal affairs. It was he who for the first time in Russia introduced strict reporting in financial affairs, and also began to clearly take into account income and expenses for the year. The Prosecutor General now almost single–handedly led the Secret Expedition, and almost all the known political affairs of the reign of Catherine II passed through his hands:
Emelyan Pugachev,
Alexander Radishchev,
Nikolay Novikov and others. Under him, the main "whip–fighter" or, as
Alexander Pushkin called him, "the domestic executioner of the meek Catherine" Stepan Sheshkovsky, who had, in the words of the empress, "a special gift to carry out investigative affairs", developed his active detective activity. Alexander Vyazemsky, unlike his predecessor, actively led the prosecutors subordinate to him. Under him, "Institutions for the Administration of
Governorates" (1775) were put into effect, which regulated in detail the rights and obligations of the local prosecutor's office. For "diligence, zeal and jealousy for the benefits of the service" he was awarded many awards, receiving, in particular, the
Orders of Saint Andrew the First–Called (1773),
Saint Alexander Nevsky,
Saint Anna,
Saint Vladimir, 1st Degree (1782),
White Eagle. Alexander Vyazemsky had the military rank of lieutenant general and the civilian rank of a
Real Privy Councillor. In September 1792, Alexander Vyazemsky retired due to illness, and Catherine II assigned the numerous duties he performed to several people.
Dmitry Bantysh–Kamensky wrote about him as follows: "Prince Vyazemsky was distinguished by his loyalty to his throne, unselfishness, was extremely hardworking, knew how to choose worthy assistants; an enemy of luxury, but stingy and envious, as his contemporaries spoke of him". Prince Vyazemsky died of paralysis on 20 January 1793; a modest tombstone can be seen in the
Annunciation Church of the Alexander Nevsky Lavra. The Murzinka Estate built by him near Saint Petersburg was inherited by his daughter Anna, and then by her grandson Anton Apraksin. ==Family==
