Russian Empire
The Russian Empire, also known as Imperial Russia or simply Russia, was an empire that existed across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917.
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.
