Motives and Technology

During the 1400s, wealthy Europeans developed a strong demand for luxury goods from Asia, especially spices like pepper and cloves, which were used to preserve and flavor food. The traditional overland trade routes that brought these goods to Europe were long and controlled by various merchants, making the final products extremely expensive for European buyers.

The expansion of the Ottoman Empire gave it control over the major land routes connecting Asia to the Mediterranean. From there, Italian city-states held a monopoly on the trade, driving prices even higher. This economic pressure motivated Atlantic nations, particularly Portugal, to finance voyages and develop new technologies. Their goal was to find a direct sea route to Asia, bypassing the old trade networks to gain access to the sources of Asian wealth.

European exploration was driven by three main motives, known as the Three Gs.

Kings and queens wanted to gain power and claim new lands for their nations (Glory). Merchants and explorers hoped to find riches like spices, silk, and gold (Gold). Religious leaders and missionaries sought to spread Christianity to new peoples across the world (God).

New inventions helped sailors navigate the dangerous "Sea of Darkness." The Magnetic Compass allowed sailors to know which direction was north. The Astrolabe used the stars to help them measure their latitude (distance north or south of the equator).

Shipbuilders also designed a new type of ship called the Caravel. It had triangular sails that allowed it to sail against the wind, making long ocean voyages possible.
