Unit 4 key ideas
Technology and motives drove exploration
The caravel, the magnetic compass, the astrolabe and better maps made long ocean voyages possible. States sponsored voyages to find new trade routes to Asia, gain wealth and spread Christianity.
The Columbian Exchange changed both hemispheres
Diseases such as smallpox killed a large share of the Indigenous population of the Americas. Maize and potatoes spread to Afro-Eurasia and helped populations grow, while horses, cattle, sugar and wheat came to the Americas.
Maritime empires ran on coerced labour
The Spanish used the encomienda system and adapted the Inca mit'a for silver mining at Potosí. The Atlantic slave trade forced millions of Africans to work on sugar plantations. Joint-stock companies such as the Dutch East India Company built trading-post empires in Asia.
Power was challenged and hierarchies changed
Rebellions such as the Pueblo Revolt challenged colonial rule. In Spanish America, a casta system ranked people by ancestry, with peninsulares at the top. Some states, such as Tokugawa Japan, limited contact with Europeans.
Common Unit 4 mistakes
- Saying the Columbian Exchange only moved goods from the Americas to Europe; it moved plants, animals, people and diseases both ways.
- Confusing encomienda (forced Indigenous labour for Spanish settlers) with chattel slavery.
- Assuming European states controlled most of Asia by 1750; they mostly held trading posts.
How to study this unit
- Draw the Columbian Exchange as two lists: what went west, what went east, and one effect of each.
- Learn one example of resistance for each region, such as the Pueblo Revolt or maroon communities.
