Structural-functionalism views society as a complex system of interconnected parts that work together to maintain stability. It focuses on identifying the functions that social institutions serve and emphasizes the importance of social order and balance. The theory analyzes how different elements of society are interdependent and contribute to its functioning. It was developed in the late 19th century by Émile Durkheim and expanded by later theorists like Malinowski, Radcliffe-Brown, and Robert Merton. While it provides insights into social order, it can oversimplify social issues and ignore power dynamics. Alternative perspectives like conflict theory criticize its focus on stability over change.
