Networks of Exchange (1200-1450)

Overland routes linking China, Central Asia, the Middle East, and Europe traded luxury goods like silk and porcelain. Caravanserai and oasis cities supported long-distance trade, while ideas and religions (Buddhism, Islam, Christianity) spread alongside merchants.

The Mongols created the largest land empire, unifying Eurasia and enforcing the Pax Mongolica. Their relay stations, standardized laws, and protection of merchants made trade safer while also spreading technologies, cultures, and diseases.

Maritime networks connected East Africa, the Middle East, South Asia, and Southeast Asia using predictable monsoon winds. Port cities and diasporic merchant communities traded spices, textiles, and ivory, fostering cultural blending in places like Swahili city-states.

Camel caravans linked West Africa to North Africa and the Mediterranean, exchanging gold, salt, and enslaved people. The wealth of Ghana and then Mali grew from this trade, and Islam spread through merchant and scholarly networks.

Trade routes carried religions, artistic styles, and technologies across Afro-Eurasia. Buddhism moved into East Asia, Islam expanded into Africa and South Asia, and scientific and mathematical knowledge circulated through translation and scholarship.

Greater interregional contact spread crops and animals, reshaping diets and landscapes. It also accelerated the transmission of diseases like the Black Death, which devastated Eurasian populations and disrupted economies.

The Silk Roads and trans-Saharan routes focused on high-value luxury goods, while Indian Ocean trade moved both bulk and luxury products. States participated differently-some taxed or protected routes, while others relied on merchant networks and port city autonomy.
