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.
Military history of the Russian Empire
The war between Russia and the Japanese Empire broke out on February 8, 1904 with a Japanese attack upon the Russian Far East Fleet stationed at Port Arthur. Plagued with logistical problems, outdated military equipment and incompetent Russian officers, Russian forces suffered numerous defeats in the course of the war, which ended in September 1905, in the aftermath of the destruction of the Russian fleet at the Battle of Tsushima. Faced with growing internal problems, including the revolution of 1905, Russia sued for peace as the war concluded with the Treaty of Portsmouth.
