Why European Explorers Sought a New Route to Asia (15th–16th C.)

Five converging forces launched the Age of Exploration:

1. Ottoman blockade – After 1453, Ottomans controlled Eastern Mediterranean land/sea routes, taxing or blocking spice caravans.
2. Profit motive – Pepper, cinnamon, cloves, nutmeg, silk, porcelain fetched fortunes; cutting out Venetian/Arab middlemen meant massive margins.
3. Renaissance curiosity – Humanism, geography, and "knowledge for its own sake" drove princes and merchants to fund voyages.
4. Technological leaps – Caravel (lateen + square rig), magnetic compass, astrolabe, portolan charts, improved cartography enabled open-ocean sailing.
5. State rivalry – Portugal (Prince Henry), Spain (Catholic Monarchs), later England/France/Netherlands competed for trade monopolies and prestige.

Result: Dias rounded Africa (1488), Columbus reached Americas (1492), da Gama reached India (1498), Magellan circumnavigated (1519–22). The world rewired.
