By Anselmo Boaventura
Short answer: Asabiyyah is Ibn Khaldun's word for group feeling, social cohesion or solidarity: the bond that makes people defend and sacrifice for each other. In the Muqaddimah (1377) he argued that a group with strong asabiyyah can found a dynasty, that the dynasty grows rich while the bond is strong and taxes are light, and that it decays after about three generations as rulers lose the bond, pile on taxes and confiscate property. His observation that low tax rates bring in more revenue than high ones was later rediscovered as the Laffer curve.
Who was Ibn Khaldun?
Ibn Khaldun was born in Tunis in 1332 and served as a judge, diplomat and courtier across North Africa and Andalusia. In 1377, sheltering in a castle in what is now Algeria, he finished the introduction to a history of the world. That introduction, the Muqaddimah, became far more famous than the history. Arnold Toynbee called it one of the greatest works of its kind ever created by any mind in any time or place.
The three-generation cycle
| Generation | Bond (asabiyyah) | Taxes | Wealth |
|---|---|---|---|
| First: the founders | Strong; rulers share hardship | Low | Rising |
| Second: the builders | Weakening; ruler separates himself | Rising | Peak |
| Third and fourth: the heirs | Lost; hired soldiers replace loyal followers | High, plus confiscation | Falling |
A new group from the edges, with fresh asabiyyah, then replaces the old dynasty. Ibn Khaldun put the usual life of a dynasty at about 120 years.

The first Laffer curve
Ibn Khaldun wrote that at the beginning of a dynasty taxation yields a large revenue from small assessments, and at the end it yields a small revenue from large assessments. Low rates encourage people to work and trade, so the number of enterprises grows and the total collected rises. High rates kill the incentive, business shrinks and revenue falls. Arthur Laffer himself credited Ibn Khaldun with the idea.
He also warned that a government that goes into trade and farming itself, competing with its own people, harms them and its revenue, and that injustice, by which he meant confiscation and forced labour, ruins civilisation, because people stop striving when what they earn is taken.
Why asabiyyah matters for Africa today
Ibn Khaldun's key insight is that a civilisation's wealth rests on a psychological and spiritual bond, not a legal contract. He also saw that faith could create group feeling far wider than any tribe.
Read colonial Mozambique through his eyes and the story is clear: forced labour (chibalo), forced cotton and a state that took more than it gave are exactly the injustice he said destroys civilisation. And the informal economy that followed is asabiyyah at the scale of the family and the savings group. The task now is to widen it to the scale of the nation.
Frequently asked questions
What does asabiyyah mean? Group feeling, social cohesion or solidarity: the bond that makes a group willing to act as one.
What is the Muqaddimah about? It is Ibn Khaldun's 1377 introduction to world history, covering how societies form, why dynasties rise and fall, and how economies, taxes, cities and crafts work.
Did Ibn Khaldun invent the Laffer curve? He described the same idea six centuries earlier: low tax rates yield large revenues and high rates yield small ones. Arthur Laffer acknowledged him as a source.
Why do dynasties last three generations, according to Ibn Khaldun? Because each generation further from the founders loses the hardship and solidarity that made them strong, turns to luxury and heavy taxes, and becomes vulnerable to a new group with fresh asabiyyah.
