Mu'jam al-Buldan (Dictionary of Countries) by Yaqut al-Hamawi is one of the most significant and comprehensive geographical encyclopedias written in the medieval Islamic world. This monumental work, presented here as Volume One of seven, meticulously compiles an extensive array of information on cities, towns, regions, and geographical features across the known world of its time. Beyond mere location, Yaqut integrates historical narratives, biographical details of notable figures associated with each place, linguistic insights, and cultural observations, making it an invaluable resource for historians, geographers, and scholars of Islamic civilization. Its detailed entries provide a vivid panorama of the medieval Islamic landscape and its rich cultural heritage.
