Count Dmitry Nikolayevich Bludov (1785–1864) was a Russian imperial official who filled a variety of posts under Nicholas I - Deputy Education Minister (1826–28), Minister of Justice (1830–31, 1838–39), Minister of the Interior (1832–38), Chief of the Second Section (1839–62). Alexander II appointed him President of the Academy of Sciences (1855) and Chairman of the State Council (1862).
Despite his distinguished official career, Bludov is also notable for his literary background. He was related by blood to Gavrila Derzhavin and Vladislav Ozerov. He was also a founding member of the Arzamas Society, with Cassandra as his alias. Bludov's personal friends included Nikolay Karamzin and Vasily Zhukovsky. It was Bludov who edited and published their posthumous works. Antonina Bludova, a writer and salon-holder, was his daughter.
Bludov headed the Russian embassy in London in 1817–20. Although on friendly terms with many of the Decembrists, Bludov presided over the court that condemned them to death. During Nicholas I's reign he was considered one of the more liberal officials. He was in charge of reorganizing the courts and drafting a new criminal code (adopted in 1845). Bludov's extensive diaries have never been published.
Leo Tolstoy described Bludov's house on Nevsky Avenue as the place "where writers, and in general, the best people of the time would gather. I remember that I read Two Hussars there for the first time. Bludov was a man who was at one time close to the Decembrists and sympathetic in spirit to the whole progressive movement. All the same he continued in government service under Nicholas".
