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.
Ohlweiler
In 1310, Ohlweiler had its first documentary mention. The village belonged to the Duchy of Palatinate-Simmern, which introduced the Reformation in 1556. Later, the Elector of the Palatinate was the landholder. Beginning in 1794, Ohlweiler lay under French rule. In 1815 it was assigned to the Kingdom of Prussia at the Congress of Vienna. Since 1946, it has been part of the then newly founded state of Rhineland-Palatinate.
