sentences:  With the diploma of the Roman Emperor Franz I (dated January 19, 1760), the real chamberlain, Lieutenant-General Roman Vorontsov, together with his brother, the real chamberlain Ivan Vorontsov, was promoted with descending descendants into the "Count of the Roman Empire dignity".In 1760, Vorontsov became a member of the Legislative Commission, in which, like the Commission on the Rights of the Nobility (1763), he advocated the legislative formalization of class rights of the nobility, including the right to exclusive ownership of serfs.With the advent of Peter III Fedorovich, his position at court was strengthened, since his daughter Elizaveta Romanovna was the favorite of the new emperor; on January 8, 1762, Roman Vorontsov received the rank of General-Chef.
