Ibn Khaldun

Abd al-Rahman ibn Muhammad ibn Khaldun was born in Tunis in 1332, into a family of Andalusian origin that had held political positions across North Africa and Iberia for generations. He served as a judge, diplomat, and adviser to multiple rulers across the Islamic world before retreating into scholarship.1

In 1377, living in a castle in what is now Algeria, he began writing the Muqaddimah, or "Introduction," to his universal history. It became one of the most ambitious works of social analysis ever produced.2

The Muqaddimah described a cyclical theory of civilizations. Nomadic groups, bound by what Ibn Khaldun called asabiyyah (group solidarity or social cohesion), conquer settled societies. Once in power, luxury and specialization erode the cohesion that brought them to dominance. Within three to four generations, the ruling group becomes dependent on hired labor, mercenary armies, and bureaucratic elites, losing its original vitality. A new group with stronger solidarity then displaces them.3

He also analyzed the economics of labor and pricing with a precision that European economists would not match for centuries. He observed that the cost of goods reflected the labor required to produce them, a principle Adam Smith would articulate four hundred years later.4

Ibn Khaldun served as chief judge of the Maliki school in Cairo and met Tamerlane during the Mongol siege of Damascus in 1401.5 He died in Cairo on March 17, 1406. Arnold Toynbee, the British historian, called the Muqaddimah the greatest work in the philosophy of history ever produced. Its analysis of how labor, solidarity, and institutional decay interact remains relevant to any society debating why its systems no longer function as their founders intended.
