First Trade
As settlements grew, people began trading surplus goods — creating the first markets and trade networks.
Barter and Beyond
When communities produced different goods, trade was natural. A coastal village with fish could trade with an inland village with grain. The earliest trade was barter — direct exchange of goods.
But barter has a problem: the 'double coincidence of wants.' You need to find someone who has what you want AND wants what you have. This limitation drove the invention of commodity money.
Ancient Trade Networks
By 3000 BCE, extensive trade networks connected Mesopotamia, the Indus Valley, and Egypt. Obsidian, lapis lazuli, copper, and textiles traveled thousands of miles. Trade routes like the later Silk Road shaped the development of entire civilizations.
- •Barter was limited by the 'double coincidence of wants'
- •Trade networks connected distant civilizations by 3000 BCE
- •Trade spread not just goods but ideas, technology, and culture
- •Comparative advantage: regions traded what they produced best
