What is "wormsgau"

The Wormsgau or pago wormatiensi was in the Middle Ages a county, which extended itself not only in the surroundings of the city of Worms, Germany, but concurrently along the Rhine widely in northern direction until short of reaching Coblenz. The city of Mainz belonged likewise to it as to the start of the 9th century also Boppard, which in reality ca. 825 was already lost again. In the 10th century the Wormsgau lost wide middlerhenish zones, mostly to the benefit of the Nahegau, thereunder Ingelheim 937, Spiesheim 960, Saulheim 973 and Flonheim 996, until the Selz after the end of this schrinkage defined the northern limit. The losses in the North could through western expansion and expansion along the Rhine, especially in the Pfälzerwald, be partially compensated.

The Wormsgau was among the central possessions of the Salian dynasty.
