What was the Islamic Golden Age? It is the name historians give to a period, roughly from the 8th to the 13th century, when scholars across the Muslim world led major advances in mathematics, medicine, astronomy, optics and philosophy. Many ideas we take for granted today were developed, preserved or refined in this era.
This guide introduces the places and people of the Islamic Golden Age and the legacy they left. Dates are approximate where historians differ.
Baghdad and the House of Wisdom
After the Abbasids founded Baghdad in 762 CE, the city grew into a centre of learning. The Bayt al-Hikmah (House of Wisdom), which flourished under the caliph al-Ma’mun in the early 9th century, brought together scholars who translated works from Greek, Persian and Sanskrit into Arabic and then built on them.
Mathematics: Al-Khwarizmi
Muhammad ibn Musa al-Khwarizmi (c. 780–850) wrote a book whose title gave us the word algebra (from al-jabr), and the Latin form of his name gave us algorithm. His work also helped spread the Hindu-Arabic numerals used around the world today.
Medicine: Al-Razi, Ibn Sina and Al-Zahrawi
- Al-Razi (c. 854–925) wrote an early clinical description distinguishing smallpox from measles.
- Ibn Sina (Avicenna, 980–1037) wrote The Canon of Medicine, taught in European universities for centuries.
- Al-Zahrawi (Abulcasis, c. 936–1013), working in Córdoba, wrote a major medical encyclopaedia with illustrated surgical instruments.
Science: Ibn al-Haytham and Al-Biruni
Ibn al-Haytham (c. 965–1040) wrote the Book of Optics, explaining vision through light entering the eye and testing ideas by experiment. Al-Biruni (973–c. 1050) was a mathematician and astronomer who estimated the Earth’s radius with notable accuracy.
Philosophy: Ibn Rushd
Ibn Rushd (Averroes, 1126–1198), a judge and philosopher from Córdoba, wrote influential commentaries on Aristotle that were widely studied in medieval Europe.
Places of Learning
Learning in the Islamic Golden Age was not confined to Baghdad. Córdoba, Cairo and Fez all became centres of scholarship. In Fez, Fatima al-Fihri founded the al-Qarawiyyin mosque in 859 CE; its school is often described as the oldest continuously operating university in the world.
Why It Flourished
Historians point to several factors: a common language of scholarship (Arabic), paper-making, which spread from the 8th century, generous patronage, busy trade routes, and a strong culture of seeking knowledge rooted in the Qur’an’s repeated call to reflect on creation, as in Qur’an 13:3 (see our guide to Quran stories for more on reflection).
How the Islamic Golden Age Ended
There is no single end date. The Mongol sack of Baghdad in 1258 is often used as a marker, but scholarship continued in Cairo, Istanbul, Isfahan and Delhi for centuries afterwards. See our overview of Islamic history for the wider story.
The Legacy Today
The legacy of the Islamic Golden Age lives on in the words we use (algebra, algorithm, alchemy), in medicine and optics, and in the art of Arabic calligraphy and geometric design that still decorates homes and buildings worldwide.
