I was doing the research why in 1400, a small country like Portugal became richest power. It was not Italy or France or Germany or British. I found the answer today.

Portugal’s rise in the 15th-16th century is a pure technology-to-economics story.

They combined three tech breakthroughs, lateen sails (lift), square sails (speed), and deep keels (stability), into caravels and carracks that could sail against the wind. This was the world’s first “physics-driven navigation system.”

With this capability, Portugal opened the direct sea route to India, mounted cannons on ships, mastered monsoon algorithms, and built the world’s first global supply chain from Lisbon to Goa to Malacca.

Result: They broke the Arab-Venetian spice monopoly, captured 2/3 of global spice trade, earned 300-600% ROI per voyage, and became the richest nation in Europe for nearly a century.

A simple insight: technology → control of routes → control of trade → economic power.

This was the first example of tech innovation creating global economic dominance.
