What is the name of a complete or complex change in all or most of the aspects of social life, affecting the foundations of the existing system, the transition from one qualitative state to another?

There are two types of social change in the world: revolution and reform. A revolution is a complex change in all aspects of life, a qualitative transition from one state to another, which occurs as a result of sharp shocks. Revolution differs from reform in its spontaneity. Its consequences cannot be predicted due to its unpredictability and abstractionism. Usually revolutions lead to a change in the political regime and the ruling circles. At the same time, the internal structure, relationships, and the form of power are changing.
