Cousins William L. Wiley (1820-1900) and James Wiley (1817-1886) founded Galva in 1854.  The name Galva honors the Swedish immigrants of nearby Bishop Hill and refers to Gävle, Sweden which is the town's sister city. Today around 80% of the town has Scandinavian ancestry. 
Galva was a railroad town. Galva was laid out along the Chicago, Burlington and Quincy Railroad (Burlington Route) with the help of Bishop Hill trustees who invested heavily in Galva.  This was the first of three rail line to locate there. This group was formed in 1852 and ran a line from Aurora, Illinois to Galesburg, Illinois. A second branch of the Burlington Route later also came through. Later the Peoria and Rock Island Railroad (Rock Island Railroad) came through Galva.

There was once a statue set between two buildings, dedicated to Rubezahl. The sculpture was enscribed, "Rubezahl, the vigilant gnome who guards your home and lights your way at the end of the day." Local teenagers would toast to Rubezahl at every passing until one day Rubezahl was found missing atop his perch in between the buildings. Several theories exist, but to this day the whereabouts of the Rubezahl statue are unknown.[dubious ]
