The Conestoga wagon was instrumental in the transportation of goods and people for both consumer and military purposes. Originating in England, early Pennsylvania craftsmen perfected the vehicle's design for use in the colonies, especially the roads of Pennsylvania. German craftsmen in Lancaster and Berks Counties were best known for their wagons, and soon they were traversing the Keystone State, hauling farm goods and supplies between towns and markets. Of course, these wagons then play a key role in the westward migration.
