Ibn Khaldun

Asabiyyah is a core concept in Ibn Khaldun's philosophy, best translated as social cohesion, group solidarity, or tribal loyalty. He argued in the Muqaddimah that dynasties rise to power when they possess strong asabiyyah, but eventually fall within a few generations as they become corrupt and lose this desert toughness. This cyclical theory of history laid the groundwork for early sociology.

The Muqaddimah serves as the introductory book to Ibn Khaldun's massive universal history, Kitab al-Ibar. Completed in 1377, it is considered a foundational text in sociology, economics, and historiography because it attempts to find the natural laws governing societal development. It deeply analyzes how environmental, economic, and psychological factors impact the rise and fall of human civilizations.

Yes, Ibn Khaldun famously met the Turco-Mongol conqueror Timur, also known as Tamerlane, outside the walls of Damascus in 1401. Ibn Khaldun, then in his seventies, was lowered over the city walls in a basket and spent several weeks in Tamerlane's camp. He wrote a lengthy, detailed report of his observations of the conqueror and his army during this encounter.

Ibn Khaldun lived a highly itinerant life across North Africa and the Middle East during the turbulent 14th century. He held various political positions, taught at universities, and worked as a jurist in cities including Tunis, Granada, and Cairo. His constantly shifting fortunes were largely driven by the complex political rivalries of the various Islamic dynasties of the era.
