Russian journalist who exercised a high degree of influence in government circles during the reigns of Alexander II (reigned 1855–81) and Alexander III (reigned 1881–94).

After study at the Moscow University (graduated 1838) and the University of Berlin (1840–41), Katkov was an assistant professor of philosophy at Moscow (1845–50). In 1851 he became editor of the daily Moskovskiye Vedomosti (“Moscow News”), and in 1856 he also became editor of the journal Russky Vestnik (“Russian Courier”). During his early journalistic career, he supported the liberal reforms of Alexander II (e.g., the emancipation of the serfs and the establishment of an independent judiciary) and generally hoped to bring about the transformation of the Russian autocracy into a constitutional monarchy. After the Polish uprising of 1863, however, he became a staunch chauvinist and not only wrote articles favouring reactionary domestic policies and aggressive Pan-Slav foreign policies but also encouraged Alexander III, who regarded Katkov as one of his closest advisers, to restrict the entry of students from low social classes into secondary schools and unsuccessfully urged him to commit Russia to an anti-German foreign policy.
