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.
Russian Far East
In Russia, the region is usually referred to as just "Far East" (). What is known in English as the Far East is usually referred to as "the Asia-Pacific Region" (, abbreviated to ), or "East Asia" ().
Russia reached the Pacific coast in 1647 with the establishment of Okhotsk, and consolidated its control over the Russian Far East in the 19th century, after the annexation of part of Chinese Manchuria. Primorskaya Oblast was established as a separate administrative division of the Russian Empire in 1856, with its administrative center at Khabarovsk.
