Bandar Aceh

Bandar Aceh stands near the northern tip of Sumatra, where the Indian Ocean meets the approaches to the Malacca Strait. As the capital of the Aceh Sultanate, it became a gathering place for merchants and Muslim scholars from India, the Middle East and Southeast Asia. Pepper from Sumatra drew ships to its harbor, while its rulers competed with Portuguese Malacca and Johor for influence over the strait. After the Portuguese capture of Malacca in 1511, Muslim merchants increasingly turned to Aceh, strengthening the port and its commercial links.

In the sixteenth century Sultan Ali Mughayat Syah expanded Aceh's authority along the Sumatran coast, taking Pasai and other ports. His successors attacked Portuguese positions across the water and sought military assistance from the Ottoman Empire. Under Iskandar Muda, who ruled from 1607 to 1636, Aceh extended its reach into the Malay Peninsula, although an attack on Malacca in 1629 ended in disaster for its fleet. He also established a body of court regulations known as Adat Meukuta Alam, drawing on the authority of custom.

After Iskandar Muda's successor, a succession of women ruled as sultanas. The court remained a center of Islamic learning, even as distant territories gained greater independence. In the early nineteenth century pepper continued to enrich the ports of Aceh, and rulers at the capital sought to bring powerful coastal chiefs more firmly under their authority.
