Ibn Khaldun's Muqaddimah
How dynasties rise and fall: a forerunner of sociology

Taking refuge in a fortress on the edge of the desert, the Tunisian historian Ibn Khaldun wrote the Introduction to his world history. In it he explained how group solidarity (asabiyya) brings nomads to power and city life wears it away, so that dynasties turn over in three or four generations. He is seen as a forerunner of sociology and economics.
