Aden is one of the oldest port cities in the world, with a history rooted in deep antiquity. Located in the crater of an extinct volcano, it has served since time immemorial as a natural and well-protected harbour at the crossroads of vital maritime routes.
The history of Aden spans more than three millennia, and one of the earliest mentions of the city is found in the Old Testament, in the Book of Ezekiel, where it is listed among the trading partners of Tyre. In the ancient era, the city was known to Greek and Roman navigators as Eudaemon (Eudaemon Arabia), meaning "Happy Arabia," and was described as a prosperous transit point on the trade route between India and Egypt.
Aden owes its development and significance to several key factors. Firstly, its unique geographical position in the natural harbour of a volcanic crater on the coast of the Gulf of Aden made the city an ideal place for ships to dock and resupply. Secondly, the city was a crucial hub on the ancient "Incense Route," through which the trade of frankincense, myrrh, and spices passed, securing its status as a key transit port for centuries. Finally, control over this strategically important port was the goal of many ancient states, including the Sabaean and Himyarite kingdoms, which sought to manage the wealthy trade flows.
The early economy and culture of Aden were inextricably linked to the sea and trade. The city flourished through port fees, transshipment, and the sale of goods. As a major commercial centre, Aden was a cosmopolitan city where merchants and cultures from different parts of the world met: from Egypt and Rome to Persia and India. A striking testament to ancient engineering is the famous Tawila Tanks — a complex system of reservoirs carved into the rocks to collect and store rainwater, which was vital in the arid climate.
