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.
History of Russia
Much of Russia's expansion occurred in the 17th century, culminating in the first Russian colonisation of the Pacific in the mid-17th century, the Russo-Polish War (1654–67) that incorporated left-bank Ukraine, and the Russian conquest of Siberia. Poland was divided in the 1790–1815 era, with much of the land and population going to Russia. Most of the 19th century growth came from adding territory in Asia, south of Siberia.
