3.1

Unit 3.1 focuses on the expansion and establishment of the Spanish and Portuguese empires in the 15th and 16th centuries. Here's a summary:

### Key Points of Spanish and Portuguese Empires:

1. Motivations for Exploration:

- Gold, God, and Glory: Both Spain and Portugal were motivated by the pursuit of wealth (gold and spices), spreading Christianity, and enhancing their power and prestige.

- Competition: The rivalry between European nations pushed these two countries to explore and claim new territories.

2. Technological Advancements:

- Use of new maritime technology, such as the caravel, astrolabe, and improved maps, allowed them to navigate further and more accurately.

- The Portuguese pioneered long-distance sea travel, establishing a route around Africa to reach Asia (Vasco da Gama’s voyage).

3. Portuguese Empire:

- Exploration and Trade: Led by figures like Prince Henry the Navigator, Portugal established trade routes along the African coast and reached India, securing a spice trade monopoly.

- Brazil: Colonization of Brazil led to sugar plantations and the use of enslaved labor.

4. Spanish Empire:

- Christopher Columbus's Voyages (1492): Sponsored by Spain, Columbus's expeditions opened the Americas to European colonization.

- Conquistadors: Figures like Hernán Cortés (who conquered the Aztec Empire) and Francisco Pizarro (who conquered the Inca Empire) played major roles.

- Encomienda System: A labor system that allowed Spanish colonists to demand labor or tribute from indigenous people, often leading to harsh conditions.

- Colonial Administration: Spain established a centralized administrative system through viceroyalties to control its vast territories.

5. Impact on Indigenous Populations:

- Demographic Collapse: The spread of European diseases such as smallpox decimated indigenous populations.

- Cultural Exchange: The Columbian Exchange brought new crops and animals to and from the Americas but also contributed to economic and social changes, including forced labor.

6. Global Impact:

- Shift in Power: The Spanish and Portuguese explorations initiated the first wave of European global dominance.

- Treaty of Tordesillas (1494): An agreement brokered by the Pope to divide the New World between Spain and Portugal, giving Portugal control over Brazil and Spain most of the Americas.
