Summary of “EXPANSÃO MARÍTIMA E GRANDES NAVEGAÇÕES | Resumo de História para o Enem”
This video provides a comprehensive overview of the Maritime Expansion and the Great Navigations, highlighting their historical context, causes, key expeditions, and consequences. The content is structured into four main parts:
1. Historical Context and Motivations for Maritime Expansion
Europe faced a severe economic crisis from the 14th to mid-15th century, caused by:
- The Black Death
- The Hundred Years’ War
- Famine cycles
- Peasant revolts
- High mortality rates
This economic contraction led to scarcity of precious metals and a need for new markets. New markets were found primarily in Africa (ivory, slaves) and the East (spices like cloves, cinnamon, pepper, ginger, nutmeg; luxury goods such as Persian carpets, perfumes, incense, and Chinese porcelain).
Mediterranean trade was dominated by Italian city-states (Genoa, Venice) and Arabs, making direct access to Eastern goods difficult. Europeans sought new sea routes via the Atlantic and Indian Oceans. The spirit of crusades and religious motivations helped overcome fears of the unknown seas.
Key political and historical factors included:
- Portuguese conquest of North African Muslim territories
- The rise of centralized modern states (Iberian kingdoms, England, France) providing political and financial support for expeditions
- The fall of Constantinople (1453) to the Ottoman Turks, which disrupted Mediterranean trade routes, increased the cost of Eastern goods, and encouraged alternative routes
2. Reasons for Portuguese Pioneering in Maritime Exploration
Portugal’s advantages in maritime exploration stemmed from several factors:
- Political stability since its emergence in 1139 and early expulsion of Moors (13th century), giving it an edge over neighbors like Spain
- The Avis Revolution (1383-1385), which consolidated royal power and formed an alliance with the bourgeoisie supporting maritime expansion
- The establishment of the “School of Sagres,” fostering technical innovations such as:
- The invention of the caravel and crossbow
- Navigation tools: compass, astrolabe, quadrant, sextant, cross-staff
- Advances in nautical cartography
- Prior experience with Atlantic navigation and trade due to Moorish presence since the 8th century
This combination of political, economic, and technological factors positioned Portugal as the leader of early maritime explorations.
3. Main Routes and Expeditions
Portuguese expeditions focused on circumnavigating Africa’s Atlantic coast:
- 1415: Conquest of Moroccan territory
- 1434: Cape Bojador crossed, opening Sub-Saharan trade
- 1482: Diogo Cão reached the Congo River and Indian Ocean waters, concluding Africa was narrower to the south
- 1487: Bartolomeu Dias rounded the “Cape of Storms” (later Cape of Good Hope), entering the Indian Ocean
Spain’s entry into maritime exploration followed the unification of its monarchy (Ferdinand and Isabella) and the expulsion of Moors from Granada (1492).
- 1492: Christopher Columbus, sponsored by Spain, sailed westward aiming for the East but reached the Americas instead.
- 1494: Treaty of Tordesillas, mediated by Pope Alexander VI, divided the Atlantic between Spain and Portugal, extending the demarcation line west to include part of Brazil in Portuguese territory.
- 1498: Vasco da Gama’s expedition was the first to reach India by sea, marking the start of Portuguese military and commercial presence in the East.
- 1500: Pedro Álvares Cabral’s expedition led to the discovery of Brazil, either by accident or design.
Other notable expeditions:
- 1513: Vasco Núñez de Balboa reached the Pacific by land.
- 1519-1522: Ferdinand Magellan completed the first circumnavigation of the Earth (though he died mid-voyage); Juan Sebastián Elcano finished the journey.
4. Consequences of Maritime Expansion
The maritime expansion brought significant global changes:
- Shift of global trade dominance from the Mediterranean to the Atlantic
- Decline of Italian and Arab commercial hegemony; rise of Iberian powers (Portugal and Spain)
- Expansion and consolidation of commercial capitalism
- Indigenous genocide in the Americas linked to Catholic missionary efforts
- Beginning of the African diaspora through the transatlantic slave trade
Maritime expansion was a pivotal historical process shaping the modern world economy and geopolitics.
Key Lessons and Concepts
- Economic crises and political changes in Europe were major drivers of maritime exploration.
- Technological and navigational innovations were crucial for the success of long sea voyages.
- Competition between emerging nation-states fueled exploration and territorial claims.
- Treaties like Tordesillas illustrate early attempts to regulate global colonization.
- The great navigations had profound social, economic, and cultural impacts worldwide.
