History

The Island of Mozambique has been a significant node in the Indian Ocean trade system since at least the 10th century CE. Arab and Swahili dhow-traders used the island as a provisioning and commercial stop on the monsoon-driven trade routes connecting the Persian Gulf, the Red Sea, the East African coast, and India. Chinese porcelain and Persian beads found in archaeological excavations attest to the island deep involvement in this world economy long before European contact.

In March 1498 CE, Vasco da Gama anchored at Mozambique Island on his first voyage to India, seeking provisions and a pilot. The Portuguese quickly recognised its strategic value: a safe harbour on the East African coast with access to fresh water, food, and the monsoon winds needed to cross the Indian Ocean. By 1507 CE the Portuguese had established a fortified settlement and declared Mozambique Island the capital of their Estado da India operations in East Africa. The Fort of Sao Sebastiao, constructed from local coral stone from c. 1558 CE onwards, became the most powerful Portuguese military installation in sub-Saharan Africa; it was never taken by force.

For nearly four centuries, the island was the administrative, military, and commercial heart of Portuguese East Africa. Indian merchants, particularly Gujarati traders, established themselves in the Stone Town and became indispensable intermediaries in the trade between the African interior, the Portuguese colonial administration, and the wider Indian Ocean economy. The island changed character gradually as the slave trade expanded, the ivory trade shifted, and Portuguese power on the East African coast was challenged by the Oman Sultanate in the north. In 1898 CE, the colonial capital was transferred to Lourenco Marques (present-day Maputo), reducing Mozambique Island to a secondary port. This relative neglect preserved its historic fabric largely intact through the 20th century.
