societal collapse

Societal collapse is the breakdown of a civilization's political, economic, and social structures.

Complex societies lose their capacity to maintain infrastructure, enforce laws, or provide basic services.

The term appears in discussions of historical events like the fall of Rome and in contemporary warnings about climate change or resource depletion: Many scholars study what factors lead to societal collapse.

The phrase implies not gradual decline but systemic failure—institutions ceasing to function within a generation or two.
