Indian Ocean Commerce, 650–1750 CE: Three Eras

A Millennium of Maritime Trade Evolution

Early Period (650–1000 CE): The Cosmopolitan Islamic Expansion

• Key players: Arab/Persian merchants (from Abbasid Caliphate), Indian (Gujarati, Coromandel), Chinese (Tang/Song).
• Goods: Spices (pepper, cinnamon), textiles (Indian cotton, Chinese silk), ceramics, glass, precious metals.
• Hubs: Siraf, Basra (Persian Gulf); Malabar Coast ports (Calicut, Quilon); Guangzhou (China).
• Dynamics: Islam unifies commercial law (Sharia courts, credit instruments suftaja, hawala). Monsoon mastery enables reliable scheduling. Srivijaya (Sumatra) controls Malacca Strait choke point.

Middle Period (1000–1500 CE): Fragmentation & New Powers

• China turns inward (Song naval tech peaks, then Ming restrictions).
• Chola Dynasty (South India) projects naval power, raids Srivijaya (1025), opening space for new Southeast Asian states.
• Majapahit (Java), Malacca Sultanate (1400+) dominate straits trade.
• Swahili city-states (Kilwa, Mombasa, Sofala) flourish on gold/ivory/slave exports from Zimbabwe plateau.
• Competition: Chinese, Indian, Arab, Southeast Asian fleets vie—no single hegemon.

Late Period (1500–1750 CE): European Entry & Restructuring

• Portuguese (1498) → Dutch (VOC, 1602) → English (EIC, 1600) → French establish armed factories, forts, monopoly contracts (cartaz system).
• European demand for pepper, cloves, nutmeg, tea, textiles, silk surges.
• Silver flows (Potosi → Manila → China) lubricate trade; China becomes silver sink.
• Slave trade expands: East African captives to Middle East, India, Indonesian plantations.
• Decline of indigenous networks: By 1750, Atlantic system (triangular trade) eclipses Indian Ocean as Europe's primary commercial theater; Asian merchants marginalized or co-opted.

The Indian Ocean remained vital, but its autonomous Asian-centered commerce gave way to European-dominated, globally integrated capitalism.
