Eifelgau

The Eifelgau was a Frankish "gau" in the region of the present day Limestone Eifel in Germany.
Location and history.
The Eifelgau derives its name from the Eifel mountains between the Rhine, Ahr, Rur, Our, Sauer and Moselle rivers. It encompasses the source regions of the rivers Erft, Urft, Kyll and Ahr, and is thus located mainly in the northern and northwestern foothills of the Eifel. The Gau was part of Lower Lorraine and belonged to Ripuaria. It corresponded geographically to the Eifel Deanery of the Diocese of Cologne.
Julius Caesar, in his reports about the Gallic War (58–51 BC), called the whole mountain range between the Rhine, Meuse and Moselle, the "Arduenna Silva" ("Arduenna Forest").
Roughly around the 7th century the Franks used the term Ardennes for the mountain range and divided their empire into gaus. The Eifelgau lay east of the Ardennengau.
Over the centuries the name Eifel, originally covering the same area as the Eifelgau, came to be used for a larger and larger region. In the meantime the German part of the mountain range became known as the "Eifel", while the Belgian, French and Luxembourgian areas on the other side of the border became the "Ardennes". An exception is the eastern part of Belgium, where it is still called the Eifel.
In the 11th century the gaus lost their political relevance.
