We challenge contemporary perceptions of Yemen as a "backwater" by revealing the pivotal role of its port city, Mocha, in the making of our modern world. Historian Nancy Um delves into the fascinating history of coffee, from its origins in 15th-century Yemen to its global spread and the economic transformations it spurred. She explores the rich maritime trade routes of the Indian Ocean, highlighting Yemen's centrality as a crossroads for goods, ideas, and people long before European influence. Um discusses the Ottoman Empire's cultivation of coffee in Yemen, the rise and decline of Mocha as a trade hub, and the unique cultural adaptations of coffee consumption within Yemen itself, such as the popular Qishr drink. We also touch upon the broader impact of hot beverages and porcelain on global social and consumption patterns, revealing how these everyday items were once revolutionary technologies. Um shares insights into the ongoing efforts to revive Yemen's coffee industry and offers recommendations for further reading on Yemen's vibrant history.
