This document provides an overview of four major theories of social change: evolutionary theories, cyclical theories, conflict theories, and functionalist/dynamic theories. Evolutionary theories view social change as progress toward more complex and advanced forms of society. Cyclical theories see the rise and fall of civilizations in cyclical patterns of growth and decay. Conflict theories emphasize the forces of instability and social struggle. Functionalist theories view society as seeking equilibrium and able to absorb disruptive forces while maintaining overall stability through cultural patterns.
