The chariot is the earliest an simplest type of carriage, used in both peace and war as the chief vehicle of many ancient peoples. Chariots were built in Mesopotamia as early as 3000 BC. and in China during the 2d millennium BC. The original chariot was a fast, light, open, two- or four-wheeled conveyance drawn by two or more horses hitched side by side. The car was little else than a floor with a waist-high semicircular guard in front. The chariot, driven by a charioteer, was used for ancient warfare during the Bronze and Iron Ages, armor being provided by bronze shields. The vehicle continued to be used for travel, processions and in games and races after it had been superseded militarily.
