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.
Gollenberg, Rhineland-Palatinate
In 1815, the Congress of Vienna assigned the "Birkenfelder Land" to the Grand Duke of Oldenburg, who took charge of his new holding on 16 April 1817, naming it the Principality of Birkenfeld. On 1 April 1937, under the Greater Hamburg Act, the old principality was absorbed into Prussia, which was still a distinct entity during the Third Reich. Since 1946, it has been part of the then newly founded state of Rhineland-Palatinate.
