How did Arab and Persian Muslim settlers influence the Horn of Africa’s coastal towns?

Arab and Persian Muslim settlers significantly shaped the coastal towns of the Horn of Africa, particularly from the 10th century onward, by establishing a network of thriving trading centers. These settlements, which included ports such as Seylac (Zeila), Berbera, Marca, Baraawe, and Mogadishu, served as vital hubs in the Indian Ocean trade network, connecting the region to markets as far away as China.12

The influence of these settlers was primarily cultural and economic:

• Spread of Islam: These coastal towns became centers for the spread of Islam, which was firmly established in the northern ports by the 10th century and subsequently provided a foundation for proselytism in the interior.13
• Urban Development: The settlers developed a ring of trading towns that facilitated commerce. This interaction encouraged the adoption of new customs and, in some cases, led local populations to adopt a mythological Arabian origin.123
• Trade Integration: These centers were engaged in lively trade, exporting goods such as ivory, tortoiseshell, and ambergris, while importing items like Islamic pottery and Chinese porcelain.41

While these coastal societies were bound by sea to the broader Islamic world, their political influence remained largely confined to the coast, and their impact on the deep interior was limited.5
