From 1200 to 1450, vast trade networks connected Afro-Eurasia and shaped civilizations. The Silk Roads carried goods, religions, and technologies overland between East Asia and the Mediterranean. The Indian Ocean maritime system, powered by monsoon winds, linked East Africa, Arabia, India, Southeast Asia, and China in the most extensive pre-modern commercial network.
Trans-Saharan camel caravans moved gold, salt, and enslaved people between West Africa and North Africa, enriching empires like Mali and Songhai. These networks spread Islam, Buddhism, and Christianity; transmitted technologies like gunpowder, paper, and the compass; and carried diseases including the Black Death.
Understanding these exchange systems is essential for AP World History because they demonstrate how interconnection, not isolation, defined the medieval world.
