List of kings and dukes of Lorraine
The kings and dukes of Lorraine have held different posts under different governments over different regions, since its creation as the kingdom of Lotharingia by the Treaty of Prüm, in 855. The first rulers of the newly established region were kings of the Franks. The Latin construction "Lotharingia" evolved over time into "Lorraine" in French, "Lotharingen" in Dutch and "Lothringen" in German. After the Carolingian kingdom was absorbed into its neighbouring realms in the late ninth century, dukes were appointed over the territory. In the mid-tenth century, the duchy was divided into Lower Lorraine and [|Upper Lorraine], the first evolving into the historical Low Countries, the second became known as the Duchy of Lorraine and existed well into the modern era.
