The chariot was a fast, light, open, two-wheeled conveyance drawn by two or more horses that were hitched side by side, and was little more than a floor with a waist-high guard at the front and sides. It was initially used for ancient warfare during the Bronze and Iron Ages; but, after its military capabilities had been superseded by cavalry, as horses were gradually bred to be bigger, the chariot was used for travel, in processions, for games, and in races.
