When was the chariot invented?

Chariot originated in early Mesopotamia in about 3000 BC. These were found in monuments of Ur and Tutub and depicted the use of these vehicles in the battle parade. These include heavy-duty chariots that used solid wheels and bodywork made from wood and skins. A typical racing chariot used four horses and, as a result, could run faster.
In the earliest versions of these chariots, the wheels rotated around a fixed axle. It was in turn linked to a draft pole to the yoke of a pair of oxen. These Mesopotamian chariots were mounted by both spearman and charioteer.
