 In the course of administrative restructuring in Rhineland-Palatinate, Wahnwegen was grouped as a self-administering "Ortsgemeinde" into the "Verbandsgemeinde" of Glan-Münchweiler in 1972.Wahnwegen was, even into the 19th century, a village characterized by agriculture, in which, however, the share of the population represented by workers in other industries began to rise considerably quite early on.There was work at the nearby stone quarries and in the collieries and ironworks in the Saarland.
