Fiat currency was invented for war

I assume you meant “fiat currency.” While it’s true that fiat money, which has no intrinsic value and is not backed by a physical commodity like gold or silver, has been widely used during times of war, it wasn’t specifically invented for that purpose. The transition from commodity money to fiat money occurred gradually over time as economies evolved.

However, during wars, governments often resort to fiat currency to fund their military efforts. Fiat money provides more flexibility for governments to finance war-related expenses by allowing them to print more money without being constrained by the availability of precious metals. This has both advantages and disadvantages and can have significant economic implications. If you’re interested, I can delve deeper into the history and dynamics of fiat currency.
