Ibn Khaldun

Abu Zayd Abd al-Rahman ibn Muhammad ibn Khaldun, born on 27 May 1332 CE in Tunis, is universally recognized as the founder of sociology, the philosophy of history, and the systematic study of political economy — disciplines he created seven centuries before they were independently re-established in the European Enlightenment. His life was lived largely in the courts, prisons, and diplomatic missions of the fragmented political world of fourteenth-century North Africa and Egypt, and the turbulence of that world directly fed the depth of his insights. Orphaned at sixteen by the Black Death, which also killed many of his teachers, Ibn Khaldun entered political life young, serving as a secretary and official for a succession of Moroccan and Tunisian rulers and experiencing firsthand the patterns of court intrigue, dynastic rise and fall, and political betrayal that he would later theorize with scientific precision. He was imprisoned for a time in Fes, made enemies as quickly as he made powerful patrons, and moved between the courts of Granada, Morocco, and Tunisia in a turbulent early career. In 1375, weary of political life and its dangers, he retired with his family to the castle of Ibn Salama near Frenda in western Algeria, where in an extraordinary period of creative isolation he composed the first draft of his masterwork, the 'Muqaddimah' (Introduction or Prolegomena), in approximately five months in 1377. The Muqaddimah was intended as the introduction to a universal history of the Arabs and Berbers, but it far overshadowed the history it was meant to introduce. It is one of the most remarkable books ever written: an attempt to find the underlying laws that govern the rise and fall of civilizations, dynasties, and states, based on a systematic analysis of history, geography, economics, demography, and human psychology. Ibn Khaldun's central concept was 'asabiyya' — group solidarity or social cohesion — the force that allows nomadic or desert peoples to unite, conquer settled civilizations, establish dynasties, and then, over generations, grow soft and lose the very cohesion that made them powerful, opening the way for the next cycle. This cyclical theory of civilizational rise and decline, backed by historical evidence across centuries, anticipated Vico, Montesquieu, Marx, Toynbee, and modern social science by hundreds of years. He also analyzed the division of labor and its economic consequences, the economic effects of taxation at different levels (anticipating what would later be called the Laffer Curve in twentieth-century economics), the relationship between climate and human character, the nature of urban versus rural life, and the sociology of knowledge. In 1382 he moved to Cairo, then the greatest city in the Islamic world, and there lived out the last two and a half decades of his life, serving multiple times as a judge (qadi) in Egypt. In 1400–1401 he was in Damascus when the Mongol conqueror Timur (Tamerlane) besieged the city. In a remarkable episode, Ibn Khaldun was lowered by rope from the city walls to meet Timur personally — an encounter that lasted several weeks, during which he compiled a detailed account of the Mongol empire at Timur's request and studied the conqueror's methods and personality firsthand. It was scholarship at its most audacious: the theorist of civilizational power face to face with the most powerful destroyer of civilization of his age. Ibn Khaldun died in Cairo on 17 March 1406 CE, aged seventy-three, and was buried at one of the Sufi cemeteries outside the city gates.
