Ibn Khaldun's theory of dynastic history, economics, and group cohesion has drawn attention far beyond his North African home. He holds a unique place in the Western imagination, cited by figures as diverse as Mark Zuckerberg and President Ronald Reagan. His holistic, functionalist approach foreshadowed the development of modern social science. Whether analyzing kin-based solidarity, the role of religion in communal life, or the interplay between the universal and the particular, his emphasis on direct observation and cultural interpretation makes him a vital progenitor to contemporary anthropology.
