Revolutionary Mail

Long before American colonists sought their freedom, people relied on letters to keep in contact over distances. As the nation’s postal system was forming, letters were few. Postal costs restricted access to the mails to governments, businesses and the wealthy. The American colonies began as lonely coastal settlements, separated by dense forests. Settlers were more eager for news of their families and homelands overseas than for news from other colonies. The British government, however, needed reliable mail service throughout the American colonies for official communications with colonial governors. 

The postal system was critical to the success of the American Revolution. Committees of Correspondence used the mail to coordinate actions. Boston patriots formed the first such committee in 1764, followed the next year by a similar group in New York and later in other colonies. Such correspondence was critical in the formation of the First Continental Congress in 1774. When the British government took to opening suspected revolutionary correspondence, a publisher named William Goddard designed a distinctly American postal system to challenge the Crown post founded upon the principles of open communication, freedom from governmental interference, and the guaranteed free exchange of ideas. On July 26, 1775 the plan, now known as the "Constitutional Post" was adopted and implemented, ensuring communication between patriots and keeping the general populace informed of events during the American Revolution.

America’s Love of Letters

Following the Revolution and the establishment of the new postal system, the cost of sending a letter continued to keep mail out of the hands of most Americans. Not until the 1850s would mail begin to find its way into American’s daily lives when Congress finally agreed to lower postage rates. In addition to rate changes, educational reforms of the 1830s helped lift literacy rates, providing larger audiences of writers and readers. At the same time the evolution of manufacturing helped make envelopes more readily available to the public. Finally, the Civil War drove more Americans to their pens and papers, desperate to keep in contact with friends and family during that turbulent period. By the 1870s, letters were commonly exchanged all across the country, providing connections as people moved into new territories, beginning new lives.
