The October Revolution was the first successful socialist revolution in human history. It established the first socialist country led by the proletariat, opened up a new era for mankind to explore the socialist road, spread Marxism–Leninism to the whole world, and greatly shocked the capitalist world. The October Revolution declared to the whole world that a brand-new social system has changed from an ideal to a reality. This is the first time in human history to eliminate the unequal society of exploitation and oppression, and to try to build a fair, just and prosperous society for the first time.
The October Revolution dealt a heavy blow to imperialist rule and greatly inspired the international proletarian revolutionary movement and the liberation movement of the oppressed people in colonies and semi-colonies.
