1.6 Technological Advances and the Age of Exploration

Europeans sailed into the Atlantic and Indian Oceans from the 1400s for wealth, religion and fame. New ships, navigation tools, maps and guns made those voyages possible, and Portugal and Spain led the way.

Key terms

  • God, gold and glory
  • caravel
  • astrolabe
  • magnetic compass
  • Prince Henry the Navigator
  • Vasco da Gama

Motives: God, gold and glory

  • Gold (wealth): Asian spices like pepper, cloves, nutmeg and cinnamon sold for huge profits in Europe. Europeans also wanted West African gold and later American silver. A direct sea route would cut out Venetian, Arab and Ottoman middlemen.
  • God (religion): rulers and missionaries wanted to spread Christianity and fight Islam. The crusading spirit of the Iberian Reconquista carried into overseas voyages, and Jesuit missionaries such as Francis Xavier later followed the trade routes to India and Japan. Religion also served as a justification: conquerors claimed that bringing Christianity excused taking Indigenous peoples' land and labor.
  • Glory (fame and power): explorers wanted fame and titles, and monarchs wanted prestige and new lands. States competed with each other, so each voyage pushed rivals to sponsor their own.

The technology that made it possible

Many of these tools came from older Mediterranean, Islamic and Chinese sources. Europeans combined and improved them.

TechnologyWhat it did
CaravelSmall, sturdy Portuguese ship mixing triangular lateen sails (to sail closer to the wind) with square sails (for speed)
Sternpost rudderMade large ships easier to steer
Magnetic compassShowed direction even under cloudy skies; first used in China, it was in European use by about 1200
Astrolabe and quadrantMeasured the angle of the sun or stars to find latitude (how far north or south you are)
Better mapsPortolan charts of coastlines, Ptolemy's rediscovered Geography and, later, Mercator's 1569 map for navigation
Gunpowder weaponsCannons on ships let small crews defeat larger fleets and seize ports

Portugal goes first

Prince Henry the Navigator (1394–1460) sponsored voyages down the West African coast and gathered sailors and mapmakers. The Portuguese reached gold and enslaved people on that coast and settled Atlantic islands like Madeira.

Bartolomeu Dias rounded the Cape of Good Hope at Africa's southern tip in 1488. Vasco da Gama sailed around Africa to Calicut in India in 1498, opening a direct sea route to Asia's spice trade.

Spain sails west

Christopher Columbus, a Genoese sailor funded by Ferdinand and Isabella, believed he could reach Asia by sailing west. In October 1492 he landed in the Bahamas and then reached Caribbean islands such as Hispaniola, which he insisted were part of Asia. Other explorers soon realized these were continents unknown to Europeans.

Ferdinand Magellan's expedition for Spain (1519–1522) was the first to sail around the world. Magellan was killed in the Philippines in 1521, and Juan Sebastián Elcano brought the one surviving ship home. The trip proved how big the Pacific was.

Why states got involved

Voyages were expensive and risky, so explorers needed backers. Monarchs paid because successful voyages brought taxes on trade, a royal share of gold and silver, and land to grant to loyal nobles. This tied exploration to the new monarchies of 1.5: stronger states could fund fleets, and overseas wealth made those states stronger still. Spain set up the House of Trade in Seville in 1503 to control and tax all trade with its colonies. This was an early form of mercantilism, the idea that the state should actively build national wealth through trade and colonies; ministers like France's Colbert later made it official policy (see 3.4).

Worked examples

  1. Example 1

    Ranking causes in an argument

    Long-essay practice: Write a thesis evaluating the most important cause of European exploration from 1450 to 1550.

    Show the solution
    1. Step 1: A thesis must make a claim that can be argued, not just list causes.
    2. Step 2: Pick the cause you think mattered most and name at least one other cause to show you are weighing them.
    3. Step 3: Give a reason that previews your evidence.

    Answer: Model thesis: Although religious zeal and the search for glory motivated individual explorers, the desire for profit from Asian spices and African gold was the most important cause of European exploration from 1450 to 1550, because monarchs like Ferdinand and Isabella and Portugal's crown funded voyages chiefly to bypass costly middlemen and enrich their treasuries.

Common mistakes

  • Saying Columbus proved the world was round. Educated Europeans already knew that; Columbus's mistake was thinking the world was much smaller than it is.
  • Crediting Europeans with inventing the compass or astrolabe. They adapted tools from China and the Islamic world.
  • Listing God, gold and glory without examples. Tie each motive to a person or voyage.

On the exam

  • Causation questions on exploration reward weighing motives against technology. Say whether motive or means mattered more and why.
  • Know the order: Dias 1488, Columbus 1492, da Gama 1498, Magellan's expedition 1519–1522.

4 questions on 1.6 Technological Advances and the Age of Exploration. Pick an answer to see if you got it, and why.

On the following day [May 21] these same boats came again alongside, when the captain-major sent one of the convicts to Calecut, and those with whom he went took him to two Moors from Tunis, who could speak Castilian and Genoese. The first greeting that he received was in these words: "May the Devil take thee! What brought you hither?" They asked what he sought so far away from home, and he told them that we came in search of Christians and of spices. They said: "Why does not the King of Castile, the King of France, or the Signoria of Venice send hither?" He said that the King of Portugal would not consent to their doing so . . . .

Question 1 of 4

The crew member's answer that they came "in search of Christians and of spices" best reflects which of the following?

Question 2 of 4

The presence of merchants from Tunis in Calicut best illustrates which of the following?

Question 3 of 4

Which of the following best explains why Portugal and Spain sought a sea route to Asia in the late 1400s?

Again, we should notice the force, effect, and consequences of inventions, which are nowhere more conspicuous than in those three which were unknown to the ancients; namely, printing, gunpowder, and the compass. For these three have changed the appearance and state of the whole world: first in literature, then in warfare, and lastly in navigation; and innumerable changes have been thence derived, so that no empire, sect, or star, appears to have exercised a greater power and influence on human affairs than these mechanical discoveries.

Bacon's claim that the compass changed "navigation" connects most directly to which of the following?
