AP World History Unit 2 Notes
Networks of Exchange (1200-1450)
- Unit 2 focuses on how various states were connected through networks of exchange during the period of 1200-1450.
- These networks weren't just trade routes; they facilitated cultural diffusion, the spread of religion, languages, and technologies.
Major Networks of Exchange
- Three primary networks to study:
- The Silk Roads
- The Indian Ocean Network
- The Trans-Saharan Trail
General Developments Across Networks
- Several common developments applied to all networks:
- Geographical Expansion: All networks expanded geographically during 1200-1450, increasing connections between states.
- Innovations: Expansion was due to innovations in commercial practices and transportation technologies.
- Wealth and Power: States participating in these networks grew wealthy and powerful.
- Rise and Fall: Increased interconnectivity led to the rise of some states/cities and the collapse of others.
The Silk Roads
- Stretched across Eurasia.
- Primarily traded luxury goods like Chinese silk and porcelain.
- Reasoning for Luxury Goods: It was expensive and difficult to travel the routes, so merchants focused on high-value items.
- Increased demand for luxury goods led to increased production by Chinese, Indian, and Persian artisans.
- Peasants in areas like the Yangtze River Delta shifted from food production to luxury goods production.
Innovations Facilitating Expansion
- Two categories of innovations:
- Transportation Technologies
- Commercial Practices
Transportation Technologies
- Caravan Serai:
- Inns and guesthouses located about a day's journey apart along the routes.
- Provided safety for merchants hauling valuable goods.
- Brought merchants from diverse cultures together, leading to cultural and technological exchange.
Commercial Practices
- Money Economies:
- Use of paper money, first developed in China, to facilitate exchange.
- Revolutionized trade compared to barter economies.
- The Chinese called it the flying money system.
- Merchants could deposit bills in one location and withdraw the same amount in another, increasing ease and security.
- New Forms of Credit:
- Bills of exchange allowed merchants to receive payment from banking houses.
Rise of Trading Cities
- Increased trade led to the growth of powerful trading cities along the routes.
- Kashgar:
- Located at the convergence of two major Silk Road routes.
- Built around a river and lush valley that made it an attractive stop.
- Grew in power and wealth as trade expanded.
The Indian Ocean Network
- Existed for centuries before 1200, but expanded significantly during this period.
- Enabled by understanding of monsoon winds.
- Traded more common goods like textiles and spices, in addition to luxury goods.
Technological Innovations
- Magnetic Compass: Improved navigation.
- Improved Astrolabe: Helped determine latitude and longitude.
- Chinese Junk Ships: Massive ships with large cargo holds.
Commercial Practices
- Similar to the Silk Roads, including the adoption of various forms of credit.
Growth of States
- Swahili City-States:
- Collection of independent city states along Africa's East Coast.
- Brokered goods from the African interior (gold, ivory, enslaved people).
- Grew in power and wealth.
- Became Islamic under the influence of Muslim merchants, connecting them to Dar al Islam.
Diasporic Communities
- Settlements of ethnic people in locations outside their homeland.
- Arab and Persian communities established in East Africa, leading to intermarriage.
- Spread of Islam and the growth of Swahili states.
- Emergence of the Swahili language as a mixture of Bantu languages and Arabic words.
Zheng He
- Voyages led to technological and cultural transfers.
- Chinese maritime technology (navigation tools, shipbuilding) spread to visited places.
The Trans-Saharan Trade Network
- Expanded during 1200-1450 due to transportation technology.
Technological Innovation
- Improved Camel Saddle: Allowed for transporting larger cargo loads across the desert.
Rise of States
- Participation in the network led to increased wealth and power for various states, including the Empire of Mali.
- Conversion of Mali's leadership to Islam in the 9th century connected it to Dar al Islam's merchant network.
- Mali grew wealthy through gold trade and taxes on merchants, reaching its peak under Mansa Musa in the 14th century.
Consequences of Increased Connectivity
- Networks created both cultural and environmental consequences.
Cultural Consequences
- Transfer of Religion/Belief Systems:
- Buddhism spread into China via the Silk Roads, carried by merchants and missionaries.
- Literary and Artistic Transfers:
- Islamic scholars in Baghdad's House of Wisdom translated Greek and Roman classics into Arabic.
- These works were later transferred to Europe, contributing to the Renaissance.
- Scientific and Technological Innovation:
- Gunpowder invented in China spread to Muslim empires and later to Eastern Europe.
- Rise and Fall of Cities:
- Hangzhou in China grew wealthy due to its location on the Grand Canal.
- Baghdad was destroyed by Mongol armies.
- Travelers' Accounts:
- Ibn Battuta, a Muslim scholar from Morocco, traveled throughout Dar al Islam and wrote detailed notes about his experiences.
Environmental Consequences
Transfer of Crops:
- Champa rice introduced to China via the tribute system, leading to increased food production and population growth.
Transfer of Disease:
- The bubonic plague spread from China along trade routes, carried by rats and fleas on camels and ships.
- Caused widespread death in the Middle East and Europe.
The Mongol Empire
- The Mongol Empire facilitated connections through trade networks.
- Replaced powerful empires across Eurasia.
Key Aspects of the Mongol Empire
- Expansion:
- Established the largest land-based empire of all time.
- The Song Dynasty and the Abbasid Empire fell to the Mongols.
- By the second half of the fourteenth century, Mongols ruled this entire area through four Khanates
- Increased Trade:
- Under Mongol rule, networks of exchange increased significantly.
- The Silk Roads flourished due to the safety and continuity provided by the large empire.
- The Mongols vigorously encouraged international trade and extracted wealth by facilitating commerce on the Silk Road.
- Pax Mongolica (Peace of the Mongols) led to increased communication and cooperation across the empire.
- Cultural Transfer:
- Facilitated the transfer of Greek and Islamic medical knowledge to Western Europe.
- Mongols adopted the Uighur script as the language of policy, diplomacy, and exchange.
