Harun al-Rashid

The third major Islamic caliphate (750–1258 CE), centered in Baghdad. It presided over the Islamic Golden Age, with landmark advances in science, philosophy, literature, and the arts, forging a cosmopolitan empire that blended Greek, Persian, Indian, and Arab traditions.

Harun al-Rashid (763-809 CE) was the fifth Abbasid caliph whose reign marked the height of Abbasid power. A capable military commander, patron of learning, and ruler of a cosmopolitan empire, he presided over Baghdad at the peak of the Islamic Golden Age.

The House of Wisdom (Bayt al-Hikma) was the premier intellectual institution of the Islamic Golden Age, established in Baghdad under the Abbasid caliphs. For over a century it was the world's leading center for translation, research, and scholarship across the sciences.

Zubaidah bint Ja'far (765/766-831 CE) was the wife of the Abbasid caliph Harun al-Rashid and one of the most powerful and celebrated women of the Islamic Golden Age, remembered above all for financing the wells and reservoirs of the Darb Zubaydah pilgrim route between Baghdad and Mecca.
