Why Did Muslim Civilisation Decline? Lessons from History Every Muslim Should Know

There was a time when the Muslim world was the undisputed centre of human civilisation. From the 8th to the 14th century — the period scholars call the Islamic Golden Age — Muslim scholars, scientists, and merchants led the world in agriculture, medicine, astronomy, mathematics, philosophy, finance, and the arts. The libraries of Al-Andalusia (Islamic Spain) alone housed more books than all the libraries of Western Europe combined.

So, what happened? How did a civilisation that once lit the way for humanity find itself, centuries later, lagging behind in science, democracy, and economic development? This is one of the most important questions a Muslim can grapple with — and it is the central question that Professor Ahmet Kuru, a prominent Turkish-American scholar of political science, tackles in his landmark book, Islam, Authoritarianism, and Underdevelopment: A Global and Historical Comparison.

Kuru’s analysis is rigorous, historically grounded, and deeply relevant for Muslims today. Understanding it can help us avoid repeating the mistakes of the past and chart a wiser path forward.

The Golden Age: A Civilisation at Its Peak

To appreciate how far the decline was, we must first understand how extraordinary the heights were. Muslim merchants and scholars invented tools of finance and trade — including the forerunner of the modern cheque and the bill of exchange — that made global commerce possible. Muslim astronomers mapped the heavens; Muslim physicians wrote medical encyclopaedias that were used in European universities for centuries. Scholars like Ibn Sina (Avicenna) and Ibn Rushd (Averroes) were so towering in their intellect that they shaped the development of Western thought and launched the European Scientific Revolution.

At a time when Western Europe was still in the Dark Ages, the Muslim world was the global capital of knowledge, innovation, and civilised life.

This flourishing was not accidental. It arose from a remarkable dynamic between three classes that worked in productive tension with one another: the intellectual class (ulama and scholars), the merchant class (traders and financiers), and the political class (rulers and administrators). When these three worked together — and when the intellectual and merchant classes maintained their independence from the state — Muslim civilisation soared.

The Turning Point: When the Alliance Shifted

Kuru’s central argument is that the decline of Muslim civilisation came not from Islam itself, but from a historical shift in the relationship between these three classes. Beginning around the 12th century, he argues, a problematic alliance formed between the political and religious establishments — a fusion of state power and clerical authority that gradually crowded out the independent intellectual class and the merchant class.

When ulama become dependent on state patronage — when they derive their authority and income from the political elite rather than from their independent scholarship and the trust of the community — they lose the freedom to challenge power, to innovate in thought, and to respond to the needs of their times. This is what Kuru identifies as one of the root causes of intellectual stagnation in the Muslim world.

Simultaneously, the merchant class — which had been the engine of economic dynamism — found itself marginalised as political rulers increasingly controlled trade and economic life. Without a thriving, independent merchant class, economic innovation withered.

The Western Parallel: Why Europe Rose While the Muslim World Stagnated

Kuru draws an illuminating parallel with Western Europe. Between the 16th and 18th centuries, three transformations took place in Europe that the Muslim world did not experience. First, a gradual separation of church and state gave the intellectual class independence from religious authority. Second, the establishment of universities created a permanent institutional home for free inquiry. Third, the rise of an independent merchant class provided the economic engine for innovation and growth.

These changes enabled the Renaissance, the Protestant Reformation, the Scientific Revolution, and ultimately the Industrial Revolution. By the 19th century, the gap in scientific and economic power between the Muslim world and the West had become enormous — and this is when colonisation became possible.

Kuru is careful to note that this is not a story of Islam being inherently incompatible with progress. The problem was not the religion — it was the political and social structures that developed in particular Muslim societies at particular historical moments.

What This Means for Us Today

Kuru’s analysis carries several urgent lessons for contemporary Muslims. The first is the importance of independent scholarship. When Islamic scholars are free from political pressure and state patronage — when they speak truth to power as Hasan al-Basri did in his day — they are at their most valuable to the community. The Muslim world needs scholars who can think freely and serve their communities honestly.

The second lesson concerns the relationship between knowledge and power. Islam has always been a civilisation of ilm — of knowledge. The Prophet ﷺ commanded us to seek knowledge as “an obligation upon every Muslim”. When that spirit of inquiry is alive in a community, it produces extraordinary things. When it is constrained by political orthodoxy or social conservatism, it stagnates.

The decline of Muslim civilisation was not caused by Islam. It was caused by the misuse of power — by rulers who instrumentalised religion for political control, and by scholars who allowed themselves to be used.

The third lesson is about civic institutions. Strong, independent institutions — whether universities, professional guilds, civil society organisations, or religious bodies — are what protect a community from the arbitrary exercise of power. Building and sustaining such institutions is not just a political task; it is an Islamic obligation.

Singapore’s Example: A Community That Builds Institutions

For Singapore’s Muslim community, these lessons from history are not abstract. We live in a society that takes institutional development seriously, and our community has its own remarkable institutions — MUIS, MENDAKI, our mosques, our madrasahs — that embody the Islamic commitment to knowledge, community service, and civic life.  Alhamdulillah, these institutions remain dynamic, intellectually vibrant, and continue to serve the community. We must continue to invest in producing scholars and thinkers who are deeply grounded in Islamic knowledge and simultaneously conversant with the challenges of the modern world. 

Conclusion: Learning from Our History

The decline of Muslim civilisation is not a story of failure — it is a story of warning. It warns us against the concentration of power, the silencing of independent voices, and the neglect of knowledge. But it is also a story of possibility: because what rose once can rise again.

As Muslims, we carry within our tradition all the resources needed for civilisational renewal: a commitment to knowledge, a theology of human dignity, an ethic of justice, and a spirituality of the heart. The task is to activate these resources with wisdom, sincerity, and collective will.

May Allah, The Beneficent, The Merciful, grant our communities the wisdom to learn from our history and the independence and courage to build a better future. Ameen.
