Abū al‑Ḥasan ʿAlī ibn al‑Ḥusayn al‑Masʿūdī (c. 896 – September 956 CE) was a pioneering Arab historian, geographer, and traveler, often called the “Herodotus of the Arabs.” Born in Baghdad and later based in Cairo, he produced over twenty works on history, geography, natural science, theology, and philosophy. His magnum opus, Murūj al‑Dhahab wa Maʿādin al‑Jawāhir (The Meadows of Gold and Mines of Gems), blends universal history with scientific geography and ethnographic commentary. He followed this with Kitāb al‑Tanbīh wa al‑Ishrāf, a summary and critical revision of his earlier volumes.:contentReference{index=1}
Al‑Masʿūdī traveled extensively across the Islamic world—from Syria, Persia, Armenia, and the Caspian Sea region to India, Sri Lanka, East Africa, and possibly China and Madagascar. His firsthand observations and interactions with merchants, scholars, and local experts shaped his empirical methodology.:contentReference{index=2}
He is considered one of the earliest historians to adopt a critical, inductive approach—prioritizing eyewitness accounts, primary sources, and comparative analysis. This method anticipated the later historiographical techniques of Ibn Khaldūn.:contentReference{index=3}
His detailed descriptions of peoples, customs, geography, ecology, and trade routes enriched medieval Islamic knowledge. He corrected inherited notions (e.g. the Caspian–Aral Sea connection) through empirical research.:contentReference{index=4}
Al‑Masʿūdī broke with traditional chronicle-style historiography by organizing content by culture, region, and topic rather than strict chronology. His writing combined factual narratives with poetry, folklore, and anecdotal observations.:contentReference{index=7}
He emphasized natural forces—geology, trade winds, climate—in shaping societies. He even proposed a gradual evolutionary model from minerals to plants to animals and humans, a rare early precognition of evolutionary thinking.:contentReference{index=8}
