Portuguese Exploration of the African Coast: A Step‑by‑Step Journey

Not Random—Deliberate and Cumulative

The Portuguese didn't "fail repeatedly" before rounding Africa; they executed a systematic, multi‑decade strategy:

1. Prince Henry the Navigator (1415–1460): Sponsored voyages down the West African coast, establishing trade posts and mapping currents.
2. Bartolomeu Dias (1487–1488): Reached the Cape of Good Hope but turned back due to crew exhaustion and stormy seas.
3. Vasco da Gama (1497–1499): Built on prior knowledge, rounded the Cape, crossed the Indian Ocean, and reached Calicut, India—opening the direct sea route to Asia.

Each expedition added navigational data, established supply points, and refined ship design, culminating in da Gama's success.
