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.
History of Russia
Ivan III tripled the territory of his state, ended the dominance of the Golden Horde over the Rus', renovated the Moscow Kremlin, and laid the foundations of the Russian state. Biographer Fennell concludes that his reign was "militarily glorious and economically sound," and especially points to his territorial annexations and his centralized control over local rulers. However, Fennell, the leading British specialist on Ivan III, argues that his reign was also "a period of cultural depression and spiritual barrenness. Freedom was stamped out within the Russian lands. By his bigoted anti-Catholicism Ivan brought down the curtain between Russia and the west. For the sake of territorial aggrandizement he deprived his country of the fruits of Western learning and civilization."
The development of the Tsar's autocratic powers reached a peak during the reign of Ivan IV (1547–1584), known as "Ivan the Terrible". He strengthened the position of the monarch to an unprecedented degree, as he ruthlessly subordinated the nobles to his will, exiling or executing many on the slightest provocation. Nevertheless, Ivan is often seen as a farsighted statesman who reformed Russia as he promulgated a new code of laws (Sudebnik of 1550), established the first Russian feudal representative body (Zemsky Sobor), curbed the influence of the clergy, and introduced local self-management in rural regions.
