The ancestor of the Perovsky nobles: father of Antony Pogorelsky, grandfather of Alexey Tolstoy, great–grandfather of Sophia Perovskaya.

He received a thorough education: a special "institute" was set up for him with his brothers, in which Schlözer first introduced the teaching of statistics, under the name "Knowledge of Own Fatherland"; later he attended lectures at the University of Strasbourg.

The latter "literally disposed of him, dictated what should be taught to Russians and what not to be taught"; at his direction, the Greek language, archaeology, natural history, astronomy, chemistry and the history of philosophical systems were thrown out of the original program of the Lyceum, as "not illuminating the mind with useful truths, but darkening with delusions and bewilderments".

The failure in the fight against Czartoryski and the government's mistrust of the Jesuits forced Razumovsky to ask for resignation from the post of Minister and member of the State Council, which was given to him on August 10, 1816.

According to Vigel, all the sons of Hetman Kirill Razumovsky "were stuffed with French literature, clothed in foreign forms, considered themselves Russian Montmorency, were amiable at court and intolerable outside of it aristocrats".

To this, Prince Alexander Vasilchikov adds that the eldest of them, Alexey, was "an exorbitant pride ... and stern in the circle of his family".

Razumovsky was married on February 23, 1774, to one of the richest brides in Russia, Varvara Sheremeteva (January 2, 1750 – May 27, 1824), the second daughter of General–in–Chief Count Pyotr Sheremetev.
