Russian Empire - Wikipedia
https://en.wikipedia.org/wiki/Russian_EmpireThough the Empire was not officially proclaimed by Tsar Peter I until after the Treaty of Nystad (1721), some historians argue that it originated when Ivan III of Russia conquered Veliky Novgorod in 1478. 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.
