Rhineland
In 1946, the Rhineland was divided into the newly founded states of Hesse, North Rhine-Westphalia, and Rhineland-Palatinate. North Rhine-Westphalia is one of the prime German industrial areas, containing significant mineral deposits, (coal, lead, lignite, magnesium, oil, and uranium) and water transport. In Rhineland-Palatinate agriculture is more important, including the vineyards in the Ahr, Mittelrhein, and Mosel regions.
Heidenburg
In 1053, Heidenburg had its first documentary mention. As a result of the turmoil of the French Revolution, Heidenburg lay under French rule beginning about 1800. In 1814 it was assigned to the Kingdom of Prussia at the Congress of Vienna. Since 1947, it has been part of the then newly founded state of Rhineland-Palatinate. Since administrative reform in Rhineland-Palatinate in 1969, the municipality has belonged to the "Verbandsgemeinde" of Thalfang am Erbeskopf. In 1997, Heidenburg was awarded the title “Child- and Family-Friendly Municipality, National Winner” ("Bundessieger Kinder- und Familienfreundliche Gemeinde").
