Yemen's Rasulid Dynasty: Science, Sufism, and the Sultan Who Knew the Stars

In the 13th century, while Europe was still debating Aristotle, the Rasulid sultan al-Malik al-Ashraf Umar ibn Yusuf was building observatories in Ta'izz, writing treatises on astronomy and agriculture, and corresponding with Sufi scholars from Egypt to India. The Rasulids — a Turkoman dynasty that ruled Yemen from 1229 to 1454 — transformed the southern highlands into a crossroads of learning and trade. This episode explores their rise from Ayyubid deputies to independent sultans, their patronage of science and mysticism, and their fragile balance between Mamluk pressure, Zaydi rebellion, and the Indian Ocean spice trade. We meet al-Malik al-Muzaffar Yusuf I, who defended Yemen against the Mongols and built the great cisterns of Aden; al-Malik al-Ashraf Umar, the astronomer-sultan whose works survive in Istanbul; and the poet-sultan al-Malik al-Afdal al-Abbas, who compiled one of the earliest encyclopedias of Yemeni agriculture. We also examine the dynasty's decline: factional infighting, the rise of the Tahirids, and the slow unraveling of a remarkable experiment in Yemeni statecraft.
