Map showing the transatlantic and global routes of major early voyages of discovery and exploration by Spain, Portugal, England, and France during the 15th and 16th centuries. The map traces the journeys of explorers such as Columbus, Cabot, Magellan, da Gama, and others, with labeled paths crossing the Atlantic and encircling Africa and South America, as well as lines of demarcation dividing Spanish and Portuguese exploration zones. — European exploration Map depicting the European exploration of the New World in the 15th and 16th centuries, including the voyages made by Christopher Columbus, John Cabot, Alonso de Ojeda and Amerigo Vespucci, Pedro Álvares Cabral, Ferdinand Magellan and Juan Sebastián del Cano, Giovanni da Verrazzano, Jacques Cartier, Sir Francis Drake, and others. The lines of demarcation represent an early division between the territory of Spain (to the west) and Portugal (to the east).

European exploration fundamentally transformed global trade by shifting the focus from traditional, restricted overland and Mediterranean routes to new maritime paths, ultimately creating an interconnected, albeit exploitative, global economic system.12

New Trade Routes and Economic Shifts

The search for direct sea routes to Asia’s wealth led to the discovery of the Americas, which European powers subsequently colonized. This expansion facilitated the rise of joint-stock companies and a mercantile system where colonial powers sought to monopolize trade. Colonies were often restricted to trading exclusively with their mother country and were prohibited from developing their own manufacturing, ensuring that raw materials flowed to Europe while finished goods were sold back to the colonies.3245

The Columbian Exchange and Triangular Trade

Exploration initiated the Columbian Exchange, a massive transfer of plants, goods, and people. Crops like corn, potatoes, and cassava from the Americas revolutionized agriculture and population growth in Africa, Asia, and Europe, while sugar, coffee, and tobacco became central to the plantation economy.46

This economic integration was heavily predicated on the transatlantic slave trade, forming a triangular trade route:
* Europe to Africa: Manufactured goods (firearms, textiles, alcohol) were traded for enslaved people.7
* Africa to the Americas: The Middle Passage transported millions of enslaved people to work on plantations.7
* Americas to Europe: Raw materials and plantation products (sugar, cotton, tobacco) were shipped to Europe to supply manufacturing industries.7

This system was built on force and systemic exploitation, causing devastating impacts on indigenous populations and enslaved Africans while enriching European colonial powers.35
