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.
Empire of Japan–Russian Empire relations
In 1852, on learning of American plans to send Commodore Matthew Perry in an attempt to open Japan for foreign trade, the Russian government revived Putyatin’s proposal, which received support from Grand Duke Konstantin Nikolayevich of Russia. The expedition included several notable Sinologists and a number of scientists and engineers, as well as the noted author Ivan Goncharov, and the "Pallada" under the command of Ivan Unkovsky was selected as the flagship. After many mishaps, Putyatin signed three treaties between 1855 and 1858 by which Russia established diplomatic and commercial relations with Japan. (see Treaty of Shimoda)
