African Maritime Knowledge Shaped European Speculation About the Americas

1. The Portuguese weren t guessing they were listening

King John II s belief in a western mainland didn t come from myth or astrology.

It came from African sailors.

Reports circulated that:

Canoes from the Guinea coast (West Africa)

Loaded with trade goods

Had been found far out in the Atlantic, drifting westward

To Europeans, this was shocking.

To West Africans, it wasn t.

The peoples of the Upper Guinea Coast Wolof, Mand , Serer, and others had long traditions of:

Open ocean fishing

Long distance canoe travel

Navigating currents and winds

Trading across vast stretches of water

So when Africans said, There s land out there, Europeans took it seriously.

Europeans knew Africans were the best navigators in that region

Portugal had spent nearly a century learning from West African pilots, interpreters, and sailors.

They relied on African maritime knowledge for:

Currents

Winds

Coastal geography

Seasonal patterns

Deep water navigation

So when African canoes were found far west of Cape Verde, it wasn t dismissed as an accident it was treated as data.

The Mission

The third voyage of Columbus wasn t just another island hopping expedition.

According to Bartolom de Las Casas s abstract of Columbus s journal, the Crown wanted Columbus to verify the existence of a mainland southwest of the Cape Verde Islands.

Why?

Because King John II of Portugal believed a continent existed there. His reasoning came from reports that:

Canoes from the Guinea coast (West Africa) had been found drifting westward

These canoes carried merchandise, suggesting long distance westward travel was possible

This implied land existed far to the west land not yet claimed by Portugal or Spain

This is a fascinating detail because it shows that African maritime knowledge influenced European speculation about the Americas... [ More ]
