Today we're going to discuss the history of the postal service. In the 19th century, mail was delivered by stagecoach, which was slow and unreliable. Then, in 1860, the Pony Express was introduced in the United States. It used riders on horseback to carry mail across the country, reducing delivery time from weeks to just ten days. However, the service was short-lived, lasting only 18 months, because the telegraph quickly replaced it for urgent messages. Despite this, the Pony Express remains a symbol of the American frontier spirit.
❓ Why did the Pony Express stop operating after only 18 months?
