Hey there! Ready to explore history? Let's discover how the world became connected during the Age of Exploration!
Between 1450 and 1750, European countries started exploring the wide oceans. They wanted to find new trade routes to Asia to buy valuable spices and silk.

Three main goals drove this European expansion: Gold, Glory, and God. Kings and explorers wanted wealth, fame for their nations, and to spread their religion across the seas.
This exploration led to the Columbian Exchange. This was the massive transfer of plants, animals, and ideas between the Eastern and Western hemispheres.
The exchange had huge effects. New, easy-to-grow crops like potatoes helped Europe's population grow. However, European contact also brought deadly diseases to the Americas, which devastated Native American populations.
Let's analyze how the introduction of the potato changed Europe. Walk through the steps to explain this cause-and-effect relationship.
- Identify the event: European explorers brought the potato plant back from the Americas to Europe during the Columbian Exchange.
- Analyze the plant's traits: Potatoes grow easily in poor soil, survive cold weather, and provide a lot of energy and vitamins.
- Connect to the people: European farmers started growing potatoes. Because food became cheap and reliable, fewer people starved during cold winters.
- State the final impact: The stable food supply caused the European population to increase rapidly over the next century.
