The Indian Ocean Monsoon Network — ibn Battuta's Rihla, the Swahili Coast, Calicut, and Zheng He's Treasure Fleet

Recite FOUR PROMISES. Then: 'Whose ships were the LARGEST in the world 1405-1433?'

• Recite FOUR PROMISES
• Collect guesses (most students will say European)
• Reveal: CHINESE Zheng He Treasure Fleet under Yongle Emperor. Flagship Treasure Ships ~135m long. Compared to Columbus's Santa María ~17m — Zheng He's flagships were nearly EIGHT TIMES LONGER.

Indian Ocean monsoon trade c. 800-1500 CE — a continuous commercial network spanning East Africa to South China. Monsoon winds: SW MONSOON Apr-Sep blows westward (East Africa → India → Persia → Egypt); NE MONSOON Nov-Mar blows eastward (China → Malacca → India → East Africa). Round-trip timing predictable — merchant could plan year-round travel. Major ports: QUANZHOU (Tang-Song-Yuan-Ming China's premier port), MALACCA (Sumatran straits), CALICUT (Indian Malabar coast spice entrepôt — where Vasco da Gama would arrive 1498), CAMBAY (Gujarati merchants), ADEN (Yemeni Red Sea gateway), HORMUZ (Persian Gulf), MOMBASA + KILWA + ZANZIBAR + SOFALA (Swahili Coast). SWAHILI COAST is a Bantu-African civilization with Indian Ocean Islamic engagement — Swahili language is Bantu-base with Arabic loanwords + Arabic-script writing tradition. Major Swahili city-states governed independently 1000-1500 CE: Mogadishu, Mombasa, Kilwa, Zanzibar, Sofala. Kilwa controlled gold-trade from Great Zimbabwe interior. ibn BATTUTA (1304-1368/9) — Moroccan Berber scholar who traveled c. 1325-1354 covering ~117,000 km across the Islamic world + China + Maldives + Mali. His RIHLA (Travels) c. 1355 was dictated to ibn Juzayy. Visited Kilwa 1331 ('one of the most beautiful and well-constructed towns'), Calicut 1340s, Maldives where he served as Maliki qadi 18 months, China 1345-6, Mali 1352-3 (Lessons 9-11 already covered Mali entries). Apply MG-7 Q1-7 — especially Q4 close reading of ibn Battuta's monsoon-timing detail + Q7 Whose Golden Age for the Indian Ocean network's golden age. ZHENG HE (1371-1433) — Yongle Emperor's eunuch admiral who commanded SEVEN voyages of the Treasure Fleet 1405-1433. Voyages reached SE Asia (1405-7), Indian Ocean (1407-11 visiting Calicut), Arabian Sea + Red Sea (1417-9 reaching Aden), East Africa (1418, 1421-2 reaching Malindi + Mogadishu — famous Malindi giraffe gift to Yongle Emperor), Mecca (1431-3). Fleet sizes: 250+ ships, 27,000+ personnel. Flagship Treasure Ships ~135m long × ~55m wide (modern marine archaeology has confirmed shipyard remains at Nanjing for ships of this scale, though specific Treasure Ship measurements remain debated). After 1433 Ming Dynasty halts maritime expeditions under Confucian-bureaucrat policy shift. This is the SPACE that Portuguese Indian Ocean entry 1498 will fill.

• MG-12 Connection-FIRST — monsoon system connected East Africa to South China.

  model Indian Ocean monsoon system is annual + predictable: SW monsoon Apr-Sep blows westward (East Africa → India → Persia → Egypt); NE monsoon Nov-Mar blows eastward (China → Malacca → India → East Africa). Merchants could plan a round-trip annually — sail westward in spring with the SW monsoon, trade in summer, sail eastward in winter with the NE monsoon. This predictability enabled regular long-distance trade for 1500+ years before European arrival. Dhow + junk ship technologies optimized for monsoon sailing.

  model Q1 (WHO): ibn Battuta — Moroccan Berber Maliki scholar c. 1304-1368, traveled ~117,000 km. Q2 (WHEN + WHERE): visit 1331, Rihla dictated c. 1355 to ibn Juzayy in Morocco. Q3 (WHY + FOR WHOM): Travel-account for educated-Muslim Maghrebi audience. Q4 (CLOSE READING): names Kilwa 'one of the most beautiful and well-constructed towns', describes Sultan al-Hasan ibn Sulayman's piety + generosity. Q5 (CORROBORATION): Kilwa archaeology (Great Mosque, Husuni Kubwa palace) corroborates ibn Battuta's wealth-and-architecture description. Q6 (LIVING DESCENDANTS): Swahili peoples ARE today, ~200 million Swahili speakers in East Africa. Q7 (WHOSE GOLDEN AGE?): names Kilwa's 14th-c. golden age — the Swahili Coast civilization's apogee. OCCLUDES: contemporary Mali (Mansa Musa just decade earlier) — ibn Battuta didn't know about Mali on his 1331 voyage; would visit 1352-3.

  prompt Apply MG-7 Q1-7 to ibn Battuta's Kilwa entry.
• Whose Golden Age (Q7)? Ming maritime golden age 1405-1433 — but the policy shift ends it. G7-Spring Age of Exploration will pick up the void.

  model Yongle Emperor died 1424. His grandson Xuande Emperor continued voyages briefly. After Zheng He's 1433 final voyage, Confucian-bureaucrat faction in Beijing gained policy ascendancy under Zhengtong Emperor (r. 1435-1449), arguing maritime expeditions were costly + Confucian-virtue-ordered governance should be land-focused. By 1500, China's ocean-going Treasure-Fleet shipyards had been dismantled + maritime expeditions outlawed. This is the SPACE Portuguese Indian Ocean entry 1498 would fill. If China had continued, the global trade-power balance c. 1500 would look very different.

  prompt Why did Zheng He's voyages stop in 1433?
