What this topic is asking
Topic 1.6 asks you to explain what launched European overseas exploration after about 1450: the technological advances that made long voyages possible and the motives, religious, economic, and political, that drove them. The College Board sums up the motives as "God, gold, and glory," and the technologies as the ships and instruments that let Europeans sail the open ocean.
The technology of exploration
The motives: God, gold, and glory
European exploration was driven by a bundle of reinforcing motives:
- Gold (economic). Europeans craved direct access to the spice and luxury trade of Asia. The Ottoman Empire and Italian city-states controlled the existing eastern routes and took large profits, so finding a sea route promised enormous wealth. Hunger for bullion, gold and silver, added to this.
- God (religious). A crusading zeal to spread Christianity and continue the fight against Islam motivated rulers and explorers, especially in newly unified, fervently Catholic Spain.
- Glory (political). Competition between rival new monarchies drove states to claim trade, territory, and prestige before their neighbors did.
Why Portugal and Spain led
The Iberian kingdoms had natural advantages: long Atlantic coastlines, seafaring traditions, and strong royal backing. Portugal, under the patronage associated with Prince Henry the Navigator, pushed systematically down the African coast, eventually reaching the Indian Ocean. Spain, newly unified and flush with crusading energy, backed Columbus's westward voyage in 1492, which reached the Americas. Their head start shaped the whole age of discovery.

A. Describe: the caravel, a light, manoeuvrable ship with lateen sails that could sail against the wind, alongside the magnetic compass and astrolabe for navigation.
B. Economic motive: the desire for direct access to the spice and luxury trade of Asia, bypassing the Ottoman and Italian middlemen who controlled existing routes.
C. Reason Iberia led: Portugal and Spain had Atlantic coastlines, royal backing, and (for Spain) the resources of a newly unified crown, plus a crusading religious zeal.

A Long Essay Question (LEQ), scored on the 6-point rubric.
Thesis (1): "Economic motives, above all the search for direct access to Asian trade, were the leading driver of exploration, though religious zeal and political rivalry also propelled the voyages."
Contextualization (1): the Ottoman control of eastern trade routes and the competitive new monarchies of Iberia.
Evidence (2): the spice trade and bullion hunger; the caravel, compass, and astrolabe; Portuguese voyages around Africa and Columbus's Atlantic crossing.
Analysis (2): explain HOW the profit motive drove the voyages, then add complexity by weighing it against the religious motive (spreading Christianity) and political competition, the classic "God, gold, and glory."
