What happened
Ibn Khaldun composed the Muqaddimah in six months during seclusion. He completed his universal history Kitāb al-ʻIbar in Tunis in 1378 after returning from Qalat Ibn Salama. He developed a historical method that combined history, philosophy, sociology, and economics, centred on aṣabiyyah and cyclical civilizational change.
How we know it
The document states Ibn Khaldun wrote the Muqaddimah in six months during seclusion, completed Kitāb al-ʻIbar in Tunis in 1378, and received instruction from Moroccan, Tunisian, and Andalusian exiles. His method is described as synthesising contradictory sources without citation and prioritising story validity over transmitter credibility. These claims are all directly quoted or paraphrased from the source material.
Why it went that way
He had access to diverse teachers across North Africa and Al-Andalus. He lacked texts in Qalat Ibn Salama, forcing him to return to Tunis to finish Kitāb al-ʻIbar. His method emerged from deliberate rejection of transmitter-focused norms and a commitment to story validity — a choice stated explicitly in the source.
What is still contested
The document does not report disagreement about Ibn Khaldun’s method or conclusions. It presents his approach and results as established facts, not contested interpretations. No competing readings, rival scholars, or scholarly debates are mentioned.
What it changed
He changed how history could be written: away from transmitter-based validation toward internal coherence, critical analysis, and sociological explanation. His work reframed dynastic rise and fall as predictable outcomes of group cohesion — not divine will or individual virtue.
Is it worth your time
Yes. His method broke with centuries of Islamic historiography by treating history as a social science — not a chain of transmitters but a field of observable patterns. That shift is legible in the text itself, not inferred from later praise.
