Pfalzfeld belonged to the Lower County of Katzenelnbogen and was the seat of the "Vogtei" of Pfalzfeld. Until 1367, this "Vogtei" was held in fief from the Counts of Katzenelnbogen by the Lords of Braunshorn. As well as Pfalzfeld, the centres of Niedert, Mühlpfad, Hausbay (half) and the Nenzhäuserhof also belonged to the "Vogtei". Beginning in 1794, Pfalzfeld lay under French rule. In 1814 it was assigned to the Kingdom of Prussia at the Congress of Vienna. Since 1946, it has been part of the then newly founded state of Rhineland-Palatinate. In 1993, within the framework of a great local festival, the village's 1,100th birthday (or at least, anniversary of the first documentary mention) was celebrated.
