"Forgotten Ports of Pemba: Mkumbuu Ancient Town, Chake-Chake, and the Maldivian Wadiba During the Age of the Cape Route

Mkumbuu Ancient Town, Chake-Chake, and the Maldives During the Cape Route Era: Culture and Similarities in Dhoani and Dhow Sailing , A Window into Medieval Swahili Urbanism on Pemba Island and Sir John Gray's Insights on Wadiba

The Indian Ocean has long been a corridor of cultural and economic exchange, where distant archipelagos and coastal civilizations intertwined through monsoon winds, trade commodities, and shared seafaring traditions. On Pemba Island in Tanzania's Zanzibar Archipelago, Mkumbuu Ancient Town (formally Ras Mkumbuu or ( Ruins of the ancient city of Ras Mkumbuu) stands as a testament to medieval Swahili urbanism, while the nearby town of Chake-Chake serves as a living link to this heritage. These sites illuminate Pemba's role in pre-colonial networks that extended across the ocean, including indirect ties to the Maldives. The arrival of the Cape Route in the late 15th century disrupted these longstanding connections, as Portuguese expansion reshaped trade routes and imposed control over strategic points like the Maldives. Amid these changes, cultural similarities, particularly in traditional sailing vessels such as the Maldivian Dhoani (Dhoni) and Swahili dhow (including the iron wood Copper sewn-plank mtepe), highlight enduring maritime parallels rooted in shared Indian Ocean technologies.

Mkumbuu Ancient Town: A Medieval Swahili Trading Port

Ras Mkumbuu occupies the tip of a narrow peninsula on Pemba's western coast, northwest of Chake-Chake, near the village of Ndagoni. Its strategic headland location, protected yet open to the sea, with reefs, intertidal flats, and beaches, made it an ideal harbor for fishing, boat-building, and commerce. Erosion has revealed submerged structures, suggesting a "sunken town" reshaped by centuries of tides.

The site spans two main phases:

• Early Phase (10th–12th centuries CE): Settlement began in the 9th–10th centuries with timber buildings, clay floors, hearths, and middens. A timber mosque was rebuilt in Porites coral stone by the late 10th century, marking Islamization. Houses upgraded to coral; a cemetery with 11th-century pillar tombs emerged. The community grew modestly through regional trade.

• Later Phase (14th–16th centuries CE): Expansion to ~10 hectares near the shore included numerous stone houses (elite amid wattle-and-daub), an expanded mosque with arched mihrab, and refined features. Abandonment in the 16th century likely resulted from Portuguese incursions and instability.

Key features include a large coral-stone mosque (once among sub-Saharan Africa's largest), 14 decorated pillar tombs (some embedding Chinese bowls), stone house foundations, wells, and local pottery (Tana Tradition evolving into later wares). Imports were modest, indicating a specialized regional role.

Excavations by James Kirkman (1950s) dated settlement to the 12th century, linking it to al-Mas'udi's "Qanbalu." Later work by Mark Horton (1980s–1990s), Adria La Violette, Jeffrey Fleisher, and Sealinks Project (2012) refined dates to the 10th century. Ras Mkumbuu was a key stone-town in Pemba's network, noted in 1505 Portuguese reports as one of five kingdoms ("Mkumbuu").

Chake-Chake: Pemba's Living Capital and Gateway

Chake-Chake, Pemba's administrative and commercial capital, sits on a ridge overlooking Chake-Chake Bay. With a population of ~20,000–30,000, it serves as the island's hub, home to government offices, the Pemba Museum, and Karume Airport. The name "Chake-Chake" evokes "bustling" or "restless," fitting its role as a trade center.

Occupied from 1500–1600 CE, Chake-Chake emerged as Pemba's central town amid the decline of medieval stone-towns. Under Omani rule (post-1698) and British protectorate, it became a clove-export and market hub, with modernized harbors in the late 19th,early 20th centuries. The historic market, Old Fort (likely 18th/19th-century), and Pemba Museum preserve artifacts from sites like Ras Mkumbuu. Narrow streets, bazaars, and bay views offer an authentic Swahili experience, vibrant yet relaxed, contrasting Zanzibar's crowds.

The Maldives During the Cape Route Era: Disruption and Resilience

The Cape Route's opening, Vasco da Gama's 1498 voyage, shifted Indian Ocean trade, enabling Portuguese control over spices, cowries, and coir. The Maldives, a key producer of cowries and coir, faced direct impact. Portuguese visits began in 1507–1518, extracting tribute from Sultan Kalu Muhammad. In 1558, they occupied Malé, overthrowing the sultan and installing a puppet regime to monopolize cowrie exports and strategic atolls. This occupation (1558–1573) disrupted traditional trade, including indirect flows to East Africa.

Cultural Similarities: Dhoani and Dhow Sailing Traditions

Shared maritime heritage links Mkumbuu's era to the Maldives. The Maldivian Dhoani a multi-purpose sail vessel with lateen sails, often built from coconut timber and sewn with coir rope, mirrors Swahili vessels like the mtepe (sewn-plank boat) and broader dhow types. Both feature

Dhows gracefully glide across the waters of the Swahili Coast near Zanzibar, their distinctive triangular sails catching the breeze against a backdrop of coastal architecture and lush greenery.

• Sewn construction (coir rope stitching planks without nails), ideal for coral lagoons and reefs.

• Lateen sails (triangular, allowing tacking against wind).

• Coconut timber and coir reliance, reflecting abundant palms.

• Regional adaptations for fishing, trade, and navigation.

These similarities stem from Indian Ocean exchanges, coir and cowries traded between Maldives and Swahili ports, possibly via intermediaries (Gujarat, Arabia). Swahili dhows evolved from indigenous traditions blended with Arab influences, while Dhonis trace to Dravidian roots. Both enabled monsoon voyages, underscoring shared seafaring knowledge

Sir John Gray's 1954 Article: Insights on Wadiba

Sir John Gray's "The Wadebuli and the Wadiba" (1954) synthesizes Swahili oral traditions. He distinguished

• Wadebuli: Linked to Indian ports (Dabhol/Debul), as settlers/invaders in Zanzibar/mainland lore.

• Wadiba (singular Mdiba): Tied to "Diba Islands" (Maldives, from Sanskrit dvīpa). Gray cited Sacleux's dictionary (Mdiba as "native of the Maldives") and 15th-century Pemban accounts of Wadiba as seafarers invading eastern Pemba, ruling briefly from sites like Pujini (Mkame Mdume's palace).

Historic ruins of the Kilwa Sultanate stand majestically by the Indian Ocean, reflecting the rich heritage of this ancient Swahili city.

Gray suggested Wadiba introduced innovations: coconut cultivation, toddy tapping, sewn boats, and mosque-cemetery layouts (rare elsewhere but standard in Maldives). These "invasions" likely exaggerated trade/shipwreck contacts via monsoons.

Mkumbuu and Chake-Chake preserve Swahili urbanism's vibrancy, while the Maldives' Cape Route struggles highlight resilience amid disruption. Dhoani-dhow similarities and Gray's Wadiba insights reveal deep cultural tiescowries, coir, and seafaring knowledge bridging Pemba and Maldives. These connections remind us of the Indian Ocean's interconnected past, where medieval prosperity met early modern challenges.
