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.
Dystopian Wars
The Russian Coalition has existed as a single political union since the crowning of Ivan IV - known as Ivan Grozny: 'the Terrible' or 'the Fearsome' - as the first true Tsar of all Russia in the 16th Century. Known as the Russian Empire before 1800, it has steadily expanded its borders, most notably under the guiding hand of Romanov Tsar Peter the Great.
