In 1863 Pauline Weaver and Abraham Peeples came from California to find gold, and after they found it a rush began. In 1887 the Congress mine was formed and the town had a name. On March 14, 1895 the railroad arrived and Congress was booming. In 1910, after producing over 7 ½ million dollars, the gold ran out. A second boom began with U.S. Highway 89 in 1926. The post office moved to Congress Junction in 1938, where it remains, and the community now known as Congress is the old Congress Junction. Little remains at the original townsite. The post office was established as Congress on January 19, 1889, with Charles A. Randall as postmaster, closed on August 31, 1938, and had been established at Congress Junction on March 23, 1906, with Oliver L. Greer as postmaster, before the name changed to Congress on November 1, 1938.
