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.
Stenka Razin
Russia began the 17th century with the Time of Troubles, which lasted from 1598 to 1613. This time marked the end of the Rurik dynasty and the beginning of the Romanov dynasty (which would eventually end with the October Revolution and the execution of the last tsar, Nicholas II, and the tsarevich, Alexei Nikolaevich in 1918). Michael Romanov (tsar from 1613 to 1645) and his son Alexis (tsar from 1645 to 1676) both strove to strengthen the power of the tsar in order to stabilize the country after the turmoil of the Time of Troubles. As a result, the Zemsky Sobor and the boyar council, two other bodies of government in Russia, slowly lost influence. The Russian population went from fifteen years of "near anarchy" to the reigns of two strong, centralizing autocrats.
