This document provides an overview of the origin and development of the main social sciences disciplines: anthropology, sociology, and political science. It discusses how they emerged from philosophy and theology to become empirical sciences based on observation and evidence. Key events and thinkers that contributed to their development include the Scientific Revolution, Enlightenment period, works of thinkers like Comte, Durkheim, Marx, and Boas. Decolonization efforts aimed to make the social sciences less ethnocentric and more reflective of non-Western experiences and knowledge.
