What happened
Caliph Harun al-Rashid, who ruled the Abbasid Caliphate from 786 to 809 CE, patronized the founding of the Bayt al-Hikma, the Grand Library of Baghdad known as the House of Wisdom, established specifically to translate the classical scientific and philosophical works available anywhere in the known world into Arabic. Scholars gathered there translated the medical writings of Galen, Hippocrates, and other Greek physicians, along with major works of Greek philosophy and mathematics, drawing on manuscripts obtained from across the caliphate's territory, itself linked by trade and diplomatic routes running east toward Central Asia and China as well as west toward the Mediterranean. The World History Encyclopedia's account of the Abbasid dynasty credits the House of Wisdom with preserving Greek scientific and medical knowledge that would otherwise likely have been lost entirely.
Why it matters
Baghdad under the Abbasids sat at the western end of the same network of routes that carried Chinese paper technology into the Islamic world after Talas, and the translation movement the House of Wisdom anchored depended on exactly that kind of long-distance manuscript and material circulation; the paper Talas helped introduce made the House of Wisdom's own copying and preservation work cheaper and faster than parchment ever had.
How we know
The World History Encyclopedia's article on the Abbasid Dynasty describes Harun al-Rashid's patronage of the House of Wisdom and its translation program, based on the standard historical record of Abbasid court patronage and the surviving corpus of Arabic translations of Greek medical and philosophical texts.
