Russian Empire
Though the Empire was only officially proclaimed by Tsar Peter I following the Treaty of Nystad (1721), some historians would argue that it was truly born either when Ivan III of Russia conquered Veliky Novgorod in 1478, or when Ivan the Terrible conquered the Khanate of Kazan in 1552. According to another point of view, the term "Tsardom", which was used after the coronation of Ivan IV in 1547, was already a contemporary Russian word for empire.
Russian Empire
In 1881 Alexander II was assassinated by the Narodnaya Volya, a Nihilist terrorist organization. The throne passed to Alexander III (1881–1894), a reactionary who revived the maxim of "Orthodoxy, Autocracy, and Nationality" of Nicholas I. A committed Slavophile, Alexander III believed that Russia could be saved from turmoil only by shutting itself off from the subversive influences of Western Europe. During his reign Russia declared the Franco-Russian Alliance to contain the growing power of Germany, completed the conquest of Central Asia and demanded important territorial and commercial concessions from the Qing. The tsar's most influential adviser was Konstantin Pobedonostsev, tutor to Alexander III and his son Nicholas, and procurator of the Holy Synod from 1880 to 1895. He taught his royal pupils to fear freedom of speech and press, as well as disliking democracy, constitutions, and the parliamentary system. Under Pobedonostsev, revolutionaries were persecuted and a policy of Russification was carried out throughout the Empire.
