The Shekel — Money in Mesopotamia

# The Shekel — Money in Mesopotamia

Around 3000 BCE, in the river valleys of modern-day Iraq, the Sumerians created what many historians consider the world's first monetary system. They called the unit a **shekel** — originally a weight of barley or silver.

Crucially, this wasn't just about trading grain. The Sumerians developed **credit and debt records** on clay tablets. Merchants could borrow silver, trade with it, and repay later. Temples acted as banks. The state collected taxes denominated in shekels.

> 💡 In plain terms
> The Sumerians didn't just invent money — they invented the idea that money could represent a promise. You didn't have to physically carry silver everywhere. You could write down "I owe you X shekels" on a clay tablet and that promise itself became tradeable. That's basically what banking is, five thousand years later.

This is remarkable: debt came before coins. The earliest "money" in Mesopotamia wasn't a physical token you could hold — it was a recorded obligation. An IOU written in clay.

> ⚡ Why It Works
> When money becomes a record of debt rather than a physical object, economies can grow far beyond what physical supply allows. You're no longer limited by how much silver exists in the ground — you're limited by trust and record-keeping. This insight would be rediscovered and abused many times throughout history.
