Unit 2 Overview: Networks of Exchange (1200-1450)
Welcome to the second unit of AP World History! This unit covers the same time period as Unit 1 (1200-1450), but instead of focusing on political structures, Unit 2, titled “Networks of Exchange,” dives into the transformative global economic, cultural, and environmental changes during this era.
The post-classical period witnessed the expansion and intensification of trade networks that reshaped economies and societies across continents. This article explores the most prominent trade routes of the time, their effects, and their lasting legacies in history.
Trade Routes of the Post-Classical Era
1. Silk Roads
The Silk Roads were a network of overland and maritime trade routes that connected East Asia, the Middle East, Europe, and parts of North Africa. Spanning thousands of miles, they derived their name from the lucrative Chinese silk trade, which flourished during the Han Dynasty. By the post-classical era (1200-1450), the Silk Roads had reached their peak, facilitating not only the exchange of goods but also cultural, religious, and technological ideas.
