Port · Ayyubid Yemen under al-Mu'izz Isma'il · as at first light, 1 January 1200

Aden

The town in the crater of an extinct volcano, with its harbour and customs house, is the main port of southern Arabia for the India trade and the route to Egypt by the Red Sea.

The Zuray'ids ruled it until Turanshah's conquest of 1174; rebuilding in stone followed after 1175, and merchants came from Egypt, Sind, Gujarat, East Africa and beyond. Aden was the only gold mint of Ayyubid Yemen under Turanshah and Tughtekin, and al-Mu'izz struck coins here in 594-596. In the summer of 1198 al-Mu'izz came in person: the Jews of Aden, the last in Yemen to hold out, were made to convert, among them Madmun ibn David, head of Yemen's Jews; those who returned to Judaism were to be killed.

Foreign merchants were assembled apart, told they would not be molested, and made to pay a third of the poll tax, and a duty of 15 per 100 was ordered on goods coming and going, while the dues of the Karim merchants were left as they were.

Evidence: A contemporary Geniza letter; the governor is not pinned.
