Four-wheeled vehicle designed to be drawn by draft animals. Wagons have been used from the 1st century BC; early examples used spoked wheels with metal rims, pivoted front axles, and linchpins to secure the wheels. Ninth-century improvements in suspension made the wagon preferable to the two-wheeled cart, especially for carrying freight and agricultural produce.
