The Conestoga wagon is a large, covered wagon that was developed in the early 18th century in the United States. It was primarily used for transporting goods across long distances, especially in the western expansion. The wagon features a curved, high-sided design and a canvas cover to protect cargo from the elements. These wagons were typically pulled by teams of horses or oxen and could carry heavy loads, making them essential for pioneers and traders. The Conestoga wagon played a significant role in American history, symbolizing the movement westward during the era of westward expansion.
