Russian Empire
The Russian Empire was a historical state that existed from 1721 until 1917, when the Russian Revolution led to its collapse. It was one of the largest empires in history, stretching across Europe and Asia, and was ruled by a series of tsars. The empire was characterized by a diverse population with various ethnic groups and cultures. Significant achievements included expansion through military conquests and the development of literature, arts, and sciences. However, it faced challenges such as social inequality, political unrest, and economic difficulties, which eventually contributed to its downfall and the rise of the Soviet Union.
