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.
Russian culture
At the start of the 18th century the reforms of Peter the Great (the founder of Russian Academy of Sciences and Saint Petersburg State University) and the work of such champions as polymath Mikhail Lomonosov (the founder of Moscow State University) gave a great boost for development of science, engineering and innovation in Russia. In the 19th and 20th centuries Russia produced a large number of great and inventors.
