Unit 2 Overview: Interregional Trade Networks

Context and Unit Overview

  • Unit 2 focuses on interregional trade networks in the Eastern Hemisphere; builds on the rise of civilizations and previous topics.
  • Emphasizes connections, routes, and consequences of trade among Europe, the Middle East, Africa, and Asia.
  • Americas have limited interregional networks in this unit; major attention is on Eurasian and African exchange.

Major Trade Routes

  • Silk Road (land): Beijing to the Mediterranean, with a northern route around the Caspian Sea.
  • Trans-Saharan routes: across the Sahara, linking Sub-Saharan Africa with North Africa and the Mediterranean.
  • Indian Ocean maritime routes: coastal and island networks around the Arabian Sea, Indian Ocean, and African coast.
  • Ocean navigation expands with tech and knowledge of winds (trade winds, monsoons).

The Mongol Empire and Trade Stabilization

  • Mongol Empire becomes the largest in history, controlling vast land routes.
  • Unified governance reduces robberies and creates safer, more reliable trade networks.
  • Result: the Third Golden Age of the Silk Road, intensifying cross-cultural exchange.

Goods, Luxury Items, and What Moves

  • Land transport emphasizes luxury and high-value goods: silk, porcelain, luxury textiles, spices, jewels.
  • Coastal/ocean routes move heavier or bulkier goods: spices, gold, ivory, textiles, cotton.
  • Silk: a luxury, lightweight, durable fabric with a secret production method in China.
  • Spices: high-value, compact, important for long-distance trade.
  • Crops and commodities spread: cotton, sugar, citrus, chocolate, bananas, etc.

Currency, Banking, and Economic Concepts

  • Transition from heavy coinage to paper money and notes for large-scale trade.
  • Bank notes enable carrying large sums more safely and efficiently (early forms of banking).
  • Timbuktu and other centers become hubs for coinage and trade governance.
  • Key tech: better sails, rudders, compasses, astrolabes.
  • Understanding currents and winds (trade winds, monsoons) enables longer ocean voyages.
  • Networks shift from purely land routes to extensive Indian Ocean maritime routes.

Impacts: Positive and Negative Consequences

  • Positive: diffusion of technology, agricultural advances, nutrition, broader diet (new foods like cacao, citrus, etc.), economic growth, and spread of religions.
  • Negative: diseases and unintended consequences of contact (e.g., bubonic plague spread).
  • Native populations in the Americas dramatically affected by exchange after contact with Europeans, due to lack of immunity to Old World diseases.

Mali, Timbuktu, and Coinage

  • Timbuktu emerges as a major center in the Trans-Saharan trade network.
  • Mali ruler-ship supports trade; coinage and currency systems develop, integrating with wider networks.

Exam Skills and Last-Minute Review

  • Four Cs: Cause and Effect, Compare and Contrast, Context and Consequence, Correlation and Analysis.
  • Focus on SAQs (Short Answer Questions) and LAQs (Longer AP-style Questions); practice thesis statements.
  • Understand how trade routes caused cultural, technological, and political changes; anticipate concise, evidence-based responses.
