According to archaeologists, the wheel was created around 4000 BCE most likely separately and nearly simultaneously in Mesopotamia (in contemporary Iraq), the Northern Caucasus (Maykop culture) and Central Europe.

The oldest artifacts with illustrations portraying wheeled carts date from about 3500 BCE; nevertheless, the wheel might have remained in usage for millennia prior to these drawings were made. More recently, the oldest-known wood wheel worldwide was found in the Ljubljana marshes of Slovenia. The development of the wheel revolutionized trade and war.
