Social Studies: AP World History: Post-Classical Trade Networks

Silk Roads, Indian Ocean, and Trans-Saharan connections from c. 1200 to c. 1450

Social Studies - Grade 9-12

Instructions: Read each problem carefully. Use specific historical evidence in your answers. Show your reasoning in the space provided.
  1. 1

    Identify the three major long-distance trade networks that connected Afro-Eurasia during the post-classical period from about 1200 to 1450.

    The three major long-distance trade networks were the Silk Roads across Central Asia, the Indian Ocean trade network, and the Trans-Saharan trade network across North Africa and West Africa.
  2. 2

    Explain one reason why luxury goods such as silk, porcelain, spices, and precious metals were often traded over long distances.

    Think about the relationship between value, weight, and transportation cost.

    Luxury goods were traded over long distances because they were valuable enough to make the risks and costs of transportation worthwhile. Their high demand among elites helped merchants earn profits across large regions.
  3. 3

    Describe how the Mongol Empire affected trade on the Silk Roads.

    Consider how political unity can affect travel safety.

    The Mongol Empire increased trade on the Silk Roads by creating political stability across much of Eurasia, protecting merchants, and supporting relay stations and roads. This period of safer travel is often called the Pax Mongolica.
  4. 4

    Compare the role of camels in Trans-Saharan trade with the role of monsoon winds in Indian Ocean trade.

    Both examples involve adaptations to geography.

    Camels made Trans-Saharan trade possible because they could carry goods and survive desert conditions for long periods. Monsoon winds made Indian Ocean trade more reliable because sailors could use seasonal wind patterns to travel across the ocean and return later in the year.
  5. 5

    Explain how the spread of Islam influenced trade across the Indian Ocean and the Sahara.

    Islam influenced trade by creating shared religious, legal, and cultural practices among merchants across large regions. Muslim traders could use common institutions, trust networks, and Arabic as a language of commerce in many trading cities.
  6. 6

    A historian claims, 'Trade networks mainly moved goods, not ideas.' Use one specific example from the post-classical period to challenge this claim.

    Choose one religion or cultural practice that moved along a trade route.

    The claim can be challenged by the spread of Buddhism along the Silk Roads or the spread of Islam through Indian Ocean and Trans-Saharan trade. These examples show that merchants, missionaries, and travelers carried beliefs and cultural practices as well as goods.
  7. 7

    Describe one way that trading cities such as Kilwa, Malacca, Kashgar, or Timbuktu benefited from their locations.

    Trading cities benefited from locations where merchants, goods, and routes met. For example, Malacca grew because it controlled a key passage between the Indian Ocean and the South China Sea, while Timbuktu grew as a center of trade and learning near Trans-Saharan routes.
  8. 8

    Explain the historical significance of the Swahili city-states in the Indian Ocean trade network.

    Focus on both trade and cultural blending.

    The Swahili city-states were significant because they connected the East African interior to Indian Ocean trade. They exported goods such as gold, ivory, and enslaved people and developed a blended culture influenced by African, Arab, Persian, and Islamic traditions.
  9. 9

    What was one major effect of improved commercial practices, such as bills of exchange, credit, and banking, on post-classical trade?

    Improved commercial practices made long-distance trade easier and safer by reducing the need to carry large amounts of coin. These practices helped merchants organize transactions across distant markets.
  10. 10

    Analyze how caravanserais supported trade across Central Asia and the Middle East.

    Think of caravanserais as service stops for trade caravans.

    Caravanserais supported trade by giving merchants and animals places to rest, store goods, exchange information, and find protection. They helped make long-distance overland travel more practical and secure.
  11. 11

    Explain why diasporic merchant communities formed in port cities around the Indian Ocean.

    Diasporic merchant communities formed because merchants often settled in foreign port cities to manage trade, build trust with local partners, and take advantage of seasonal monsoon travel. These communities also helped spread languages, religions, and cultural practices.
  12. 12

    Use the terms 'continuity' and 'change' to describe one pattern in post-classical trade networks from c. 1200 to c. 1450.

    Continuity means something stayed similar, and change means something became different.

    One continuity was that long-distance trade continued to connect regions through the exchange of luxury goods. One change was that trade expanded because of improved technologies, stronger commercial practices, and the growth of powerful states such as the Mongol Empire.
  13. 13

    A map shows gold moving north from West Africa and salt moving south from North Africa. Identify the trade network and explain why both goods were important.

    The map shows the Trans-Saharan trade network. Gold was important because it was valuable in Mediterranean and Islamic markets, while salt was important in West Africa because people needed it for diet and food preservation.
  14. 14

    Explain how technological innovations such as the magnetic compass, astrolabe, and improved ship designs affected Indian Ocean trade.

    Connect technology to safer or more profitable travel.

    Technological innovations improved navigation and ship travel, which made Indian Ocean trade more efficient and reliable. These tools helped sailors travel longer distances, plan routes, and carry larger cargoes.
  15. 15

    Explain how long-distance trade contributed to both economic growth and the spread of disease in the post-classical period.

    Trade networks can move both helpful and harmful things.

    Long-distance trade contributed to economic growth by increasing the movement of goods, wealth, and commercial connections across Afro-Eurasia. It also helped spread diseases such as the Black Death because merchants, animals, and ships connected distant populations.
