service begun in the United States in 1896 to deliver mail directly to farm families. Before RFD, rural inhabitants had to pick up mail themselves at sometimes distant post offices or pay private express companies for delivery. Free mail delivery began in cities in 1863, but it took more than 20 years of agitating by the National Grange for the service to be extended.

Thomas E. Watson, a congressman from Georgia, pushed through legislation for an RFD system in 1893. Local shopkeepers, fearing competition from mail-order merchandisers, sought to delay establishment of the service, and not until October 1896 did the first five riders go out on delivery routes in rural West Virginia. After that, however, the service expanded quickly.

In 1898 officials of the Post Office announced that any group of farmers could have free delivery merely by sending a petition—along with a description of their community and roads—to their congressman. The flood of petitions was overwhelming, and by 1905 the Post Office was serving 32,000 RFD routes.

In 1913 the RFD system was supplemented by Parcel Post. The mail-order houses boomed as a consequence; but, more important, rural families were no longer isolated from contemporary thought and fashion in 20th-century America.
