Trace connections among places and people. Distinguish movement of goods from movement of knowledge and practices. A network can connect distant regions through many shorter journeys.
Worked example
An item can pass through several traders before reaching a distant buyer. That does not require one trader to travel the entire network.
Connections Across Regions
The Silk Roads connected regions through changing overland and maritime routes. Merchants and other travelers exchanged many goods, while cities became places of cultural and intellectual contact. Silk was important, but the networks also carried ideas and skills. Routes and their importance changed over time.
