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.
