Impact of 1500s Navigation Tech on European Trade Routes

New tools (astrolabe, compass, improved cartography) enabled precise open-ocean navigation. This allowed Europeans to:

• Sail around Africa (Cape of Good Hope) directly to Asia, bypassing overland Middle East routes.
• Shift trade dominance from Mediterranean to Atlantic ports.
• Launch Portuguese and Spanish maritime empires.
• Initiate the Columbian Exchange (biological transfer between Americas and Afro-Eurasia).

Result: Global trade networks reoriented; Europe gained direct access to Asian spices/goods; Mediterranean cities (Venice, Genoa) declined; Atlantic powers rose.
