AP World History: Modern — Unit 2 Review
Unit 2: Networks of Exchange (c. 1200–1450)
Big idea: Trade connected different parts of the world. It spread goods, religions, technology, people, and diseases.
2.1 — The Silk Roads
What were they?
A network of overland trade routes connecting China, Central Asia, the Middle East, and Europe.
Why did trade grow?
Increased demand for luxury goods.
Improvements in transportation and trade.
Powerful empires protected some trade routes.
Merchants developed better financial systems.
Important vocabulary
Caravanserai: Inns where merchants rested and protected their goods.
Bills of exchange: Documents that allowed merchants to make payments without carrying large amounts of cash.
Paper money: Currency that made commercial transactions easier.
Luxury goods: Expensive products such as silk, porcelain, and spices.
Important places: Samarkand and Kashgar were major trading cities.
Remember: The Silk Roads mainly carried valuable luxury goods because transporting heavy products over land was expensive.
2.2 — The Mongol Empire
Who were the Mongols?
Nomadic peoples from the Central Asian steppe who built the largest contiguous land empire in history.
Important leaders
Genghis Khan: United Mongol tribes and began major conquests.
Kublai Khan: Established the Yuan dynasty in China.
Pax Mongolica: A period when Mongol rule helped make travel and trade across much of Eurasia safer.
Positive effects
Increased trade across Eurasia.
Improved communication between regions.
Spread of technologies, ideas, and cultural practices.
Negative effects
Conquests destroyed cities and caused widespread deaths.
Increased movement helped diseases spread.
Remember: The Mongols were both destructive conquerors and facilitators of trade.
2.3 — Exchange in the Indian Ocean
What was it?
A maritime trade network connecting East Africa, the Middle East, South Asia, Southeast Asia, and East Asia.
Why did trade grow?
Monsoon winds: Seasonal winds that sailors used to plan voyages.
Compass: Helped sailors determine direction.
Astrolabe: Helped sailors estimate their position using celestial observations.
Improved ships allowed merchants to carry more goods.
Important places and people
Swahili city-states: East African coastal cities that grew wealthy through trade.
Gujarat: A major trading region in western India.
Malacca: An important port connecting Asian maritime routes.
Zheng He: Chinese admiral who led major voyages during the Ming dynasty.
Cultural effects
Islam spread to coastal communities.
Merchants settled in foreign ports.
Cultures blended through interactions between local people and visiting merchants.
Remember: Indian Ocean trade depended on ships and seasonal winds and carried luxury goods as well as bulk goods.
2.4 — Trans-Saharan Trade Routes
What were they?
Trade routes crossing the Sahara Desert and connecting North Africa with West Africa.
Why did trade grow?
Camels could travel long distances with limited water.
Camel saddles helped transport goods.
Organized caravans made desert travel more practical.
What was traded?
North Africa | West Africa |
|---|---|
Salt | Gold |
Manufactured goods | Other regional products |
Important people and places
Mansa Musa: Ruler of the Mali Empire known for his wealth and pilgrimage to Mecca in 1324.
Mali Empire: Became wealthy partly through its involvement in gold and salt trade.
Timbuktu: A center of trade, Islamic scholarship, and education.
Cultural effects
Islam spread through merchants and scholars.
Islamic learning and literacy expanded in West Africa.
Remember: Gold and salt were major trade goods, and trade helped Mali become wealthy.
2.5 — Cultural Consequences of Connectivity
Big idea: Trade spread ideas and beliefs, not just products.
Islam: Spread through merchants, scholars, and Sufi missionaries into parts of Africa and Asia.
Buddhism: Spread along trade routes into Central, East, and Southeast Asia.
Technology: Papermaking and gunpowder spread from China to other regions.
Diasporic communities: Groups of merchants living outside their homeland while maintaining connections to their original culture.
Cultural diffusion: The spread of ideas, beliefs, customs, and technology between societies.
Syncretism: The blending of different cultural or religious traditions.
Remember: Religions could spread through trade without military conquest. Local communities often adapted new beliefs to their own traditions.
2.6 — Environmental Consequences of Connectivity
Big idea: Increased trade and movement affected agriculture, populations, and the environment.
Positive effects
Crops spread to new regions.
New agricultural practices increased food production in some places.
Improved food supplies could support population growth.
Negative effects
Diseases spread along trade routes.
The Black Death, a devastating plague pandemic, spread across parts of Eurasia during the 14th century.
Epidemics caused massive population losses and disrupted economies.
Important example: Champa rice
Originally from Vietnam.
Spread to China.
Could mature quickly and helped increase agricultural production.
Remember: Connectivity spread useful crops and technologies, but it also contributed to the spread of deadly diseases.
2.7 — Comparison of Economic Exchange
Know how to compare the three major trade networks.
Feature | Silk Roads | Indian Ocean | Trans-Saharan |
|---|---|---|---|
Type | Overland | Maritime | Overland |
Regions | East Asia, Central Asia, Middle East, Europe | East Africa, Middle East, South Asia, Southeast Asia, East Asia | North Africa and West Africa |
Main transportation | Camels and caravans | Ships | Camels and caravans |
Important goods | Silk, porcelain, luxury goods | Spices, textiles, porcelain, bulk goods | Gold, salt |
Key development | Caravanserai and financial systems | Monsoon winds and sailing technology | Camel saddles and caravans |
What did all three have in common?
Connected distant regions through trade.
Spread religions, technologies, and cultural practices.
Helped trading cities and states become wealthy.
Increased the movement of people and goods.
Could spread diseases between regions.
Remember: Geography shaped how each network operated. Land routes depended on caravans, while maritime trade depended on ships and knowledge of seasonal winds.
