The first one lasted from the beginnings in the 11th century until the first divisions of the county between two Sponheimish lines around 1234.
The “Further” County (Vordere Grafschaft) of Sponheim was ruled by the line Sponheim-Kreuznach with residence at Castle Kauzenburg near Kreuznach.
The "Hinder" County (Hintere Grafschaft) of Sponheim was ruled by the Sponheim-Starkenburg line, with residence at first at Castle Starkenburg near Enkirch and after 1350 at Castle Grevenburg near Trarbach.
Finally in the third phase both parts of the county were managed by joint rulers as a condominium.
