What happened with money after the roman empire?

After the fall of the Roman Empire, the use of money underwent significant changes, leading to a decline in trade and the fragmentation of the economy across Europe. The stable currency system established by Rome deteriorated, resulting in a reliance on barter and local currencies. This period, often referred to as the Dark Ages, saw the rise of feudalism, where land ownership became more critical than currency. Over time, as stability returned, new forms of money and trade began to re-emerge, paving the way for the eventual revival of commerce in the late medieval period.
