Classical sociological theory forms the foundation of modern sociology, offering key insights into the structure and function of society. It emerged during the 19th and early 20th centuries, a time of rapid social change due to industrialization, urbanization, and political upheaval. The theories developed by early sociologists such as Karl Marx, Max Weber, Emile Durkheim, and others, have shaped the way we understand social structures, power dynamics, individual behavior, and the evolution of societies.
