Ibn Khaldun Writes the Muqaddimah

In a North African fortress, Ibn Khaldun writes the Muqaddimah and founds the science of civilization itself.

Withdrawing from politics, Ibn Khaldun set out to explain why states rise and fall, and produced a theory of social cohesion, economics and history that anticipated modern sociology by five centuries. He later taught in Cairo and served as its chief judge. Historians East and West still study him as a founder of their craft.
