Arab historian and geographer, author of a history of the world, Tāʾrīkh ibn Wāḍiḥ (“Chronicle of Ibn Wāḍiḥ”), and a general geography, Kitāb al-buldān (“Book of the Countries”).

Until 873 al-Yaʿqūbī lived in Armenia and Khorāsān, under the patronage of the Iranian dynasty of the Ṭāḥirids, and wrote his history there. After the fall of the Ṭāḥirids he trav eled to India and the Maghrib (North Africa) and died in Egypt.

The Tāʾrīkh ibn Wāḍiḥ is divided into two parts. The first is a comprehensive account of pre-Islāmic and non-Islāmic peoples, especially of their religion and literature; it includes extracts from the Greek philosophers and accounts from stories and fables. The second part covers Islāmic history up to 872. The author's Shīʿite bias pervades the work.

In the Kitāb al-buldān, a large part of which is lost, al-Yaʿqūbī analyzes statistics, topography, and taxation in describing the larger cities of Iraq, Iran, Arabia, Syria, Egypt, the Maghrib, India, China, and the Byzantine Empire.
