History of Russia
The war ended in 1721 when an exhausted Sweden sued for peace with Russia. Peter acquired four provinces situated south and east of the Gulf of Finland, thus securing his coveted access to the sea. There, in 1703, he had already founded the city that was to become Russia's new capital, Saint Petersburg, as a "window opened upon Europe" to replace Moscow, long Russia's cultural center. Russian intervention in the Commonwealth marked, with the Silent Sejm, the beginning of a 200-year domination of that region by the Russian Empire. In celebration of his conquests, Peter assumed the title of emperor, and the Russian Tsardom officially became the Russian Empire in 1721.
History of Western civilization
The years between 1870 and 1914 saw the expansion of Western power. By 1914, the Western and some Asian and Eurasian empires like the Empire of Japan, Russian Empire, Ottoman Empire, and Qing China dominated the entire planet. The major Western players in this New Imperialism were Britain, Russia, France, Germany, Italy, and the United States. The Empire of Japan is the only one non-Western power involved in this new era of imperialism.
