The Black Death

Ibn Khaldun (1332–1406)

Ibn Khaldun was a North African historian, social theorist, and statesman whose Muqaddimah (Prolegomena) is considered one of the foundational works of sociology, historiography, and political science. Born in Tunis in 1332, Ibn Khaldun lost both his parents to the plague in 1349, and the pandemic’s impact on North African society profoundly shaped his intellectual development and his analysis of civilisation.

Life and Career

Abd al-Rahman Ibn Khaldun was born in Tunis in 1332 into a family of scholars and administrators who had fled Seville during the Christian reconquest of al-Andalus. He received a thorough education in the Islamic sciences — theology, law, philosophy, and history — and entered government service at an early age.

Ibn Khaldun’s career was marked by frequent changes of employer and location. He served various rulers in North Africa and Granada, was imprisoned on several occasions, and spent periods in retirement devoted to study and writing. His most productive period was the years 1375–1379, which he spent in the castle of Ibn Salama in western Algeria, where he composed the Muqaddimah.

The Muqaddimah and the Plague

The Muqaddimah, completed in 1377, is the introductory volume of Ibn Khaldun’s universal history, the Kitab al-‘Ibar (Book of Lessons). The work is a theoretical treatise on the nature of civilisation, analysing the factors that cause states and societies to rise, flourish, decline, and fall.

Ibn Khaldun incorporated the plague into his analysis of civilisation. He argued that the pandemic’s devastating impact on population, economic activity, and political stability demonstrated the fragility of human societies and the importance of the social solidarity (asabiyyah) that sustained political power. The depopulation caused by the plague, he argued, led to the decline of cities, the weakening of states, and the erosion of the cultural and economic infrastructure that sustained civilisation.

The Significance of Ibn Khaldun’s Analysis

Ibn Khaldun’s analysis of the plague was remarkable for its sociological perspective. Rather than interpreting the pandemic solely as a divine punishment or a medical phenomenon, he analysed its effects on the social, economic, and political structures of civilisation. This approach anticipated the methods of modern sociology and historical demography.

Ibn Khaldun’s concept of asabiyyah — social solidarity or group cohesion — was central to his analysis. He argued that the plague weakened asabiyyah by destroying the social networks, the shared experiences, and the institutional structures that bound communities together. The resulting fragmentation made societies vulnerable to external conquest and internal collapse.

Legacy

Ibn Khaldun died in Cairo in 1406, where he had served as chief judge of the Maliki school of Islamic law. His Muqaddimah was widely read in the Islamic world and was eventually translated into European languages, where it influenced the development of sociology, historiography, and political science. His analysis of the plague remains one of the most sophisticated contemporary interpretations of the pandemic’s impact on civilisation.
