About
The Islamic Golden Age (approximately 750-1258 CE) — centered on the Abbasid Caliphate and its capital Baghdad (the 'Round City') — was one of history's greatest intellectual flowerings, during which Muslim scholars preserved, translated, and significantly advanced ancient Greek, Persian, and Indian knowledge in mathematics, astronomy, medicine, chemistry, philosophy, and optics while European scholarship was in relative stagnation.
Key figures and contributions: Al-Khwarizmi ('father of algebra' — his Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala, c. 830 CE, gave algebra its name and our word 'algorithm' comes from his Latinized name); Ibn Sina/Avicenna (Canon of Medicine, 1025 CE — the standard medical textbook in Europe and the Islamic world until the 17th century); Al-Biruni (determined Earth's circumference to within 1% without leaving Arabia in 1020 CE); Ibn al-Haytham (Book of Optics, 1021 CE — correctly described how vision works, founding modern optics); Al-Razi (pioneered evidence-based medicine, first to use cotton swabs and catgut for sutures); and Omar Khayyam (solved cubic equations geometrically and revised the Persian calendar to be more accurate than the Gregorian). The Bayt al-Hikma (House of Wisdom, Baghdad) was the institutional center of translation and scholarship.

Fascinating Facts
- ◆The word 'algorithm' comes from al-Khwarizmi's Latinized name (Algoritmi) — a Persian mathematician whose work on Hindu-Arabic numerals was translated into Latin in the 12th century as 'Algoritmi de numero Indorum,' and the procedure for calculating described in his book was named after him
- ◆Ibn al-Haytham (Al-Hazan) was placed under house arrest by the Caliph Al-Hakim for 10 years (c. 1011-1021) — he feigned madness to avoid the Caliph's anger — and used this forced isolation to write the Book of Optics (Kitab al-Manazir), which correctly described how vision works, founded the scientific study of optics, and influenced Roger Bacon, Kepler, and Descartes
- ◆The Mongol sack of Baghdad (1258 CE) killed an estimated 200,000-800,000 people and threw the books of the House of Wisdom into the Tigris River — according to legend, the river ran black with ink for days — ending the Abbasid Caliphate and the Islamic Golden Age in a single catastrophic event
