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.
Grünstadt
After Napoleon's downfall, Grünstadt passed in 1816 to the Kingdom of Bavaria. It remained Bavarian for exactly 130 years, until the new state of Rhineland-Palatinate was founded in 1946.
