Some European sailors and conquistadors have smallpox.
Sailors come in contact with Native Americans, who contract the disease and die after infecting their relatives and neighbors, who continue to spread the disease.
Unintended: Europeans did not intentionally infect Native Americans with diseases.
Europeans bring rice and wheat with them and plant the crops in the New World.
Rice and wheat become important crops in many parts of North America.
Intended: Europeans intended to grow rice and wheat in the New World to supplement the native crops.
Europeans take potatoes from the New World back to Europe.
Potatoes become an important crop, so much so that some European countries begin to depend on them as their main food source.
Both:
Intended: Europeans intended to grow potatoes in Europe to supplement the native crops.
Unintended: Some European countries became overly dependent on the potato as a food source.
Affluent Europeans buy sugar from merchants in European cities.
Millions of people in Africa are kidnapped by African slave traders and sold to European sugar cane planters in the Caribbean.
Unintended: The demand for sugar in Europe became so great that sugar cane growers needed more workers to tend crops. They expanded the slave trade that had started in Africa and brought slaves to the Americas to tend the crops.
