The U.S. Post Office was granted a monopoly in 1775 and has operated under federal protection ever since. To enable the Post Office Department to serve all Americans, no matter how remote, yet still finance its operations largely from its revenue, Congress gave the Department a monopoly over the carriage of letter-mail by a group of federal laws known as the Private Express Statutes. On February 20, 1792, Congress enacted its first major postal law under the U.S. Constitution.
