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.
New Imperialism
"The Great Game" (Also called the "Tournament of Shadows" (, "Turniry Teney") in Russia) was the strategic economic and political rivalry and conflict between the British Empire and the Russian Empire for supremacy in Central Asia at the expense of Afghanistan, Persia and the Central Asian Khanates/Emirates. The classic Great Game period is generally regarded as running approximately from the Russo-Persian Treaty of 1813 to the Anglo-Russian Convention of 1907, in which nations like Emirate of Bukhara fell. A less intensive phase followed the Bolshevik Revolution of 1917, causing some trouble with Persia and Afghanistan until the mid 1920s.
