Ober-Ohmbach's houses clustered around a mediaeval church in the middle of a graveyard that stood on a mountain spur, while Nieder-Ohmbach stretched out on a hill south of the Weitersbach.

A newer residential area with a big new building zone with a fire station, a kindergarten and a playground stretches beneath a mountain slope on the Ohmbach's left bank.

[4] Bearing witness to early settlers in the area are prehistoric barrows within Ohmbach's own limits and also on land held by all the neighbouring municipalities.

A great barrow from an unknown time lies on the heights of the Knechtenberg, but it is damaged, reportedly after having been half dug away in 1945 by the Wehrmacht.

Weitersbach long remained in the Reichsland, whereas Ohmbach passed as a Frankish king's donation into the ownership of the Archbishopric of Mainz sometime before 976.

Ohmbach thus did not belong, as often assumed, from its founding to the Remigiusland, but rather was held, like the villages of the parish of Niederkirchen in the Oster valley, by the Archbishopric.

A place named Ovenbach, mentioned in 967 in connection with the Saviour's Chapel (Salvatorkapelle) in Frankfurt, cannot be the same place as this one in the Palatinate, for in the course of a reorganization of the bishoprics within the Archbishopric of Mainz on the Rhine’s left bank by Archbishop Willigis beginning in 976, Ohmbach passed into the ownership of Disibodenberg Abbey.

In 1112, Count Gerlach I founded the County of Veldenz and at the same time took over the Vogtei over extensive ecclesiastical landholds, among them Disibodenberg Abbey and the Remigiusland.

Gerlach V of Veldenz bequeathed the parish of Ohmbach to the Werschweiler (now Wörschweiler) Monastery, under whose ownership it remained until the time of the Reformation.

Parts of the Reichsland with the village of Weitersbach in the court district of Kübelberg were acquired in 1375 by Elector Palatine Ruprecht I as an Imperial pledge.

During the time of the Reformation, Ohmbach lay in the Duchy of Palatinate-Zweibrücken while Weitersbach belonged to the Electorate of the Palatinate.

Thus, Nieder-Ohmbach experienced a brief interlude as a Zweibrücken holding, but this lasted only about a decade before the French Revolution broke out.

Ober-Ohmbach and Nieder-Ohmbach now formed for the first time a single municipality under the name Commune d’Ohmbach, which lay in the Mairie (“Mayoralty”) of Konken, the Canton of Kusel, the Arrondissement of Birkenfeld and the Department of Sarre.

By the time of the 1933 Reichstag elections, after Hitler had already seized power, the Nazis fared no better than 21.1% in terms of local support (as against 92.5% in Horschbach[8] or 90% in Ehweiler,[9] for instance).

Nevertheless, Hitler's overall success in these elections paved the way for his Enabling Act of 1933 (Ermächtigungsgesetz), thus starting the Third Reich in earnest.

With respect to membership in Christian denominations, it can be noted that about the same number of Protestants and Catholics live in the village, whereas historically, owing to the territorial development in feudal times outlined above, most of the Protestants lived in the former village of Oberohmbach, and most of the Catholics in Niederohmbach.

The name Weitersbach for Niederohmbach is drawn from the smaller brook that flows by the village, later emptying onto the Ohmbach.

As Weytersbach, this name can be found in a 1541 border description of the court district of Kusel, and in the description of the Oberamt of Lichtenberg by Johannes Hoffmann as Weittersbach (Daran stoßen zusammen die Bännen Ohmbach, Steinbach und Weittersbach).

[12] Southeast of Ohmbach once lay a village called Remmweiler, sometimes also wrongly named as Rennweiler, bearing witness to which today are only rural cadastral toponyms.

[13] With a fair amount of certainty, Ohmbach was as long ago as the Early Middle Ages the location of a church and a parish hub.

Hence, it seems unlikely that the church would have been owned only one year later by the Saviour's Chapel (Salvatorkapelle) in Frankfurt, as it would seem to say in Emperor Otto II's 977 document acknowledging such ownership.

About 1250, the Benedictine abbey at Disibodenberg was dissolved, and the Counts of Veldenz bought up part of the monastery's holdings.

In 1954, within the deaconry of Kusel, the pastoral community of Herschweiler-Pettersheim was newly founded, to which also Ohmbach, Krottelbach and Langenbach belonged.

The municipal election held on 7 June 2009 yielded the following results:[15] "FWG" is a "free voters' group".

The arms have been borne since 1971 when they were approved by the now defunct Rheinhessen-Pfalz Regierungsbezirk administration in Neustadt an der Weinstraße.

It is part of the Begehbares Geschichtsbuch (“Accessible” or “Walk-in History Book”) that leads through the Verbandsgemeinde of Schönenberg-Kübelberg with three hiking loops and many points of interest.

Beginning in 1888, there were also job opportunities at Isidor Trifuß's diamond-cutting workshop at the Neumühle (“New Mill”) between Ohmbach and Brücken.

Thereafter, the bottom fell out of the diamond-cutting industry in the Brücken area and the great boom is now only a memory.

Ohmbach is today held to be an attractive residential community with shops, good public utilities and a lively club life.
