A revolution (from the Latin revolutio, "a turn around") is a fundamental change in power or organizational structures that takes place in a relatively short period of time. Its use to refer to political change dates from the scientific revolution occasioned by Copernicus' famous De Revolutionibus Orbium Coelestium. Aristotle described two types of political revolution:

1. Complete change from one constitution to another

2. Modification of an existing constitution.

Revolutions have occurred through human history and vary widely in terms of methods, duration, and motivating ideology. Their results include major changes in culture, economy, and socio-political institutions.
