 Both villages originally lay in the Nahegau, which beginning in the 12th century split itself up into various “undercounties” ("Untergrafschaften"), and it is difficult to know which one or ones the two villages belonged to.As early as 1287, Wiesweiler had its first documentary mention in a document from the Hornbach Monastery, according to which the monastery's abbot confirmed for another monastery, Hane (or Hagen) near Kirchheimbolanden, an income in "Wiswilre".This place, however, belonged to the Waldgravial-Rhinegravial "Hochgericht auf der Heide" (“High Court on the Heath”).
