From 1450 to 1750, European maritime exploration transformed global connections. Portuguese and Spanish voyages opened sea routes to Asia and the Americas. The Columbian Exchange transferred plants, animals, diseases, and people between hemispheres, devastating indigenous populations while transforming agriculture and diets worldwide.
The Atlantic slave trade forcibly transported millions of Africans to the Americas, creating plantation economies. Colonial systems -- Spanish encomienda, Portuguese Estado da India, Dutch VOC -- reshaped societies and economies. Silver from the Americas flowed through Manila to China, creating the first truly global economy.
These transoceanic connections produced both unprecedented exchange and unprecedented exploitation.
One step at a time.
Adjust the controls and watch the concepts respond in real time.
The massive transfer of plants, animals, diseases, people, and ideas between the Americas and the Old World after 1492.
Example: Potatoes from the Americas became a staple food in Europe, while smallpox devastated indigenous American populations.
The forced transportation of millions of Africans to the Americas between the 16th and 19th centuries to work on plantations.
Example: An estimated 12.5 million Africans were forcibly shipped across the Atlantic, with perhaps 2 million dying during the Middle Passage.
Spanish colonial system granting colonists the right to demand labor and tribute from indigenous people in exchange for supposed protection and religious instruction.
Example: Bartolome de las Casas documented the brutal exploitation of indigenous people under the encomienda system.
Economic theory holding that national wealth is measured by gold and silver reserves, and that colonies exist to enrich the mother country through favorable trade balances.
Example: Spain extracted massive quantities of silver from Potosi mines in Bolivia, shipping it to Europe.
The forced voyage of enslaved Africans across the Atlantic Ocean, marked by horrific conditions, disease, and high mortality.
Example: Enslaved people were packed into ships with minimal space, food, and sanitation for voyages lasting 6-8 weeks.
