Harun al-Rashid

Hārūn al-Rashīd, born Abū Jaʿfar Hārūn ibn Muḥammad ar-Rashīd in Rey (in modern-day Iran) sometime between 763 and 766, was the fifth Abbasid caliph. He ruled from September 786 until his death on 24 March 809. His reign is often seen as the start of the Islamic Golden Age. The title "al-Rashīd" means "the Just," "the Upright," or "the Rightly-Guided."

He founded the famous Bayt al-Ḥikma (House of Wisdom) library in Baghdad, which grew into a global hub for knowledge, culture, and trade. During his rule, the Barmakid family—key figures in establishing the Abbasid Caliphate—lost influence. In 796, he moved his court and government to Raqqa in present-day Syria. Domestically, he followed policies similar to his father al-Mahdi, freeing many Umayyads and ʿAlids imprisoned by his brother al-Hadi and declaring amnesty for all Quraysh political groups. Large-scale wars broke out with Byzantium, and under him the Abbasid Empire reached its peak.

In 799, a Frankish mission came to offer friendship. Harun sent gifts back with the envoys to Charlemagne’s court, including a clock that Charlemagne and his retinue thought was magic because of the sounds and tricks it performed each hour. Parts of the fictional *One Thousand and One Nights* are set in his court, and some stories feature him. His life and court have inspired many tales, both true and invented.

**Early life**

Harun was the son of Caliph al-Mahdi and al-Khayzuran, a strong-willed woman who greatly influenced state affairs during her husband’s and sons’ reigns. As a child, he studied history, geography, rhetoric, music, poetry, and economics, but mostly focused on mastering hadith and the Quran. He also trained physically as a future fighter, practicing swordplay, archery, and military arts.

Before becoming caliph, he nominally led campaigns against the Eastern Roman Empire in 780 and again in 782. The second expedition was massive, reaching the Asian suburbs of Constantinople. According to the chronicler al-Tabari, the Byzantines lost tens of thousands of soldiers, and Harun used 20,000 mules to carry back the spoils. After this, the price of a sword fell to one dirham and a horse to a single gold dinar. These raids boosted his political standing, earning him the epithet "al-Rashid." He was made crown prince and put in charge of the empire’s western territories, from Syria to Azerbaijan.

When his father died in 785, Harun’s brother al-Hadi became caliph, but his reign lasted only a year and two months. Al-Hadi clashed with their mother over her influence and tried to replace Harun as crown prince with his own son, Jaʿfar. Al-Khayzuran strongly opposed this and favored Harun, who was dutiful to her. Al-Hadi eventually barred her from state affairs, forbidding anyone from approaching her door. He threatened to behead any commander or servant who visited her, saying, “Do you not have a spindle to occupy you, a Qur’an to remind you, or a house to protect you?” Al-Khayzuran left the palace, swore never to speak to him again, and moved to another house. Al-Tabari gives different accounts of al-Hadi’s death—either from an abdominal ulcer or assassination possibly ordered by his mother.

**Caliphate**

On the night of al-Hadi’s death, al-Khayzuran freed Yahya ibn Khalid from prison and ordered him to pay the army, send letters to governors demanding allegiance to Harun, and prepare him as caliph. Commanders Harthama ibn Aʿyan and Khuzayma ibn Khazim were summoned to swear allegiance. Khuzayma reportedly gathered and armed 5,000 of his followers, dragged al-Hadi’s son Jaʿfar from his bed, and forced him to publicly renounce his claim.
