Above the village, the Kesselberg's broad slope on the river's left bank formed even after the Second World War an extensive vineyard area.

[4] Within Offenbach-Hundheim's limits, the Ortsteil of Hundheim lies south of the Glan in the valley of the Talbach, which here empties into the millrace feeding Offenbach's Klostermühle ("Monastery Mill").

Offenbach was originally a linear village (by some definitions, a "thorpe") on the Glan's left bank, near which a monastery had arisen in the Gölschbach valley.

In 1906, the railway line began running between Dorfstraße ("Village Street") and the Glan, and in 1938, parallel to this, the approach road to what is today Bundesstraße 420.

The most striking building is Hirsau Church mentioned above, standing in the west of the Glan valley in the middle of the old graveyard and built in the early 12th century.

According to the record in which Offenbach had its first documentary mention, Archbishop Heinrich of Mainz (1142-1153) acknowledged that the edelfrei nobleman Reinfried had donated a plot of land to Saint Vincent's Benedictine Abbey in Metz.

The story about him taking part in a Crusade and after successfully coming back from the campaign endowing the monastery to fulfil a vow is at least a fine legend.

Offenbach belonged in the Middle Ages to the Hochgericht auf der Heide ("High Court on the Heath"), at which the Waldgraves exercised jurisdiction.

Notum sit omnibus sanctae dei ecclesiae fidelibus nostrisque praesentibus scilicet et futuris, qualiter quidam nobilis vir nomine Heririh tradidit quasdam res proprietatis suae ad monasterium Primiae, quod est constructum in honore sancti Salvatoris, coram istis fideiussoribus, quorum nomina sint: Megingaudus comes, Milo, item Megingaudus vicedominus, Brunicho, Hunaldus, Ratadus, id est in Locis, que vocantur glena, seu quod ipse… and the rest of the text deals with Windesheim and Bingen.

Dependence on a great number of lords in the dale afforded greater freedom than in other areas where united power and governing relationships prevailed.

Legal matters within the Eßweiler Tal were governed by a whole range of Weistümer (plural of Weistum), which were already in force in the Middle Ages, although they were not actually set down in writing until the early 16th century.

One deals with the court and borders, one is a Kanzelweistum (promulgated at church; Kanzel is German for "pulpit"), one is a Huberweistum (Huber were farmers who worked a whole Hube, which roughly corresponds to an "oxgang"), and one was a municipal Weistum (Gemeindeweistum).

In 1656, when the Rhinegraves wanted to sell the provostry off from its mother monastery, Saint Vincent's Abbey in Metz, the deal fell through because of objections raised by the Zweibrücken lords protector.

In no way was it held to be a good circumstance throughout the centuries for the village of Offenbach to be under the Rhinegraves’ ownership and for the provostry, with all its holdings, including the church stewardship since the Reformation, to be under the protection of the Counts Palatine (Dukes) of Zweibrücken.

Thus, in 1754, Christian IV, Count Palatine of Zweibrücken and Rhinegrave Karl Walrad Wilhelm forged an agreement to end this state of affairs.

With respect to lordly relations, in 1595 there was a change: the high jurisdiction, which for some 250 years had been held by the Waldgraves and Rhinegraves, was transferred to the Counts Palatine of Zweibrücken.

[16] Offenbach, as a village lying mainly on the Glan's left bank, now became the seat of a mairie ("mayoralty") within the Department of Sarre, the Arrondissement of Birkenfeld and the Canton of Grumbach.

Also belonging to the Mairie of Offenbach were the villages of Wiesweiler, Buborn, Deimberg, Niedereisenbach (Ortsteil of Glanbrücken), Sankt Julian, Eschenau and Niederalben.

Later, after the First World War, the Treaty of Versailles stipulated, among other things, that 26 of the Sankt Wendel district's 94 municipalities had to be ceded to the British- and French-occupied Saar.

After a transitional time, Hundheim was grouped into the bayerischer Rheinkreis, later known as Rheinpfalz ("Rhenish Palatinate"), an exclave of the Kingdom of Bavaria in 1816, where it became the seat of a new Bürgermeisterei ("mayoralty") to which also belonged the villages of Nerzweiler, Aschbach, Hinzweiler and Hachenbach, within the Landcommissariat (later Bezirksamt, then Landkreis or district) of Kusel and the Canton of Lauterecken.

Given the rather great share of the population that is Catholic, it can be assumed that newcomers from France came to settle in Offenbach as a direct result of French policy at that time.

[23] Toponym researchers assume that today's Ortsteil of Hundheim in the municipality of Offenbach-Hundheim was originally called Glana or Glene, and perhaps also Neuenglan, a name that would have distinguished it from Altenglan (alt and neu are German for "old" and "new" respectively).

Between Hundheim and Nerzweiler, on the Talbach's right bank, once lay a small village named Letzweiler, which was never mentioned again in documents after the Thirty Years' War.

Beginning in 1601, Hinzweiler became the temporary parish seat, but already by 1610, it once again had to yield this function to Hirsau, only to get it back after the Thirty Years' War, after the Hirsauer Kirche had been badly damaged.

The bend (slanted stripe) and the two other charges, the rose and the mullet (six-pointed star shape), were the elements that already appeared on an Offenbach court seal in the 16th century.

As early as the 18th century, collieries were being worked somewhat successfully on the slopes either side of the Talbach, as were also pits within Niederaschbach's former limits, land that for a while had belonged to Offenbach before being ceded to Hundheim.

There are reports of the beginnings of school in Offenbach from as long ago as the 16th century, according to which the children had to go to a schoolmaster named Johannes Matthias Faber for Lutheran Kinderlehre ("child teaching").

After him came Abraham Ruth from Blaubach, and in 1855, Wilhelm Frick from Duchroth (not to be confused with the like-named Nazi) was hired, who had for six years been the schoolteacher in Obereisenbach.

Frick's first wife, Margarethe (née Ginkel) had died in Obereisenbach, and he was now seeking leave to marry Philippine Braun from Becherbach.

Beginning in 1906, Offenbach lay on the Glan Valley Railway (Glantalbahn) running from Bad Münster am Stein to Homburg, but this was shut down in stages about 1985.
