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.

Up to the 19th century, the areal possession of the Russian Empire in North America included the modern-day U.S. state of Alaska and settlements in the modern-day U.S. states of California (1 settlement) and Hawaii (3 settlements, starting in 1817). These Russian possessions were collectively and officially referred to by the name Russian America from 1733 to 1867. Formal incorporation of the possessions by Russia did not take place until the establishment of the Russian-American Company (RAC) in 1799.
