9.2 Metal trade routes and exchanges

Metal trade routes shaped ancient economies and cultures. From the Silk Road to maritime networks, these pathways facilitated the exchange of precious metals, technologies, and ideas across vast distances.

The Roman Empire expanded existing trade networks, while medieval systems like the Hanseatic League dominated northern European commerce. These routes played a crucial role in the spread of metallurgical knowledge and the development of global trade.

Early Modern Trade

Transatlantic Commerce

• Triangular trade connected Europe, Africa, and the Americas from 16th to 19th centuries

  • Second leg (Middle Passage): Enslaved Africans transported to Americas
  • Third leg: Colonial goods (sugar, tobacco, cotton) shipped to Europe
  • Resulted in forced migration of millions of Africans
  • Contributed to economic growth of European powers and development of plantation economies in Americas
  • Led to significant demographic and cultural changes in all three continents

Historical Trade Disruptions

• Bronze Age collapse disrupted Mediterranean and Near Eastern trade networks around 1200 BCE
  • Resulted in widespread societal collapse and loss of writing systems in affected regions
  • Possible causes include invasions, climate change, and technological shifts
  • Led to decline of major civilizations (Mycenaean Greece, Hittite Empire)
  • Disrupted long-established trade routes and economic systems
  • Resulted in "Dark Age" lasting several centuries in some areas
  • Eventually led to rise of new powers (Greek city-states, Phoenicians) and trade networks
