Ibn Khaldun

Ibn Khaldun (27 May 1332 – 17 March 1406) was an Arab scholar, historian, philosopher, and sociologist. He is widely considered one of the greatest social scientists of the Middle Ages and a major forerunner of historiography, sociology, economics, and demography. His most renowned work is the *Muqaddimah* (or *Prolegomena*), which served as an introduction to his universal history, *Kitāb al-ʻIbar*. In the *Muqaddimah*, Ibn Khaldun introduced concepts such as *asabiyyah* (group cohesiveness) and analyzed the cyclical rise and fall of civilizations, the influence of environment on society, and the role of government. His ideas on economic growth, division of labor, and taxation have been compared to those of later European economists like Adam Smith and David Ricardo. Ibn Khaldun had a dynamic political career, serving rulers in various North African states before settling in Cairo, Egypt, where he held judicial and teaching positions. He interacted with significant historical figures, including Timur (Tamerlane). His intellectual legacy continues to be studied and debated by scholars worldwide.
