The villages of Rohrbach, Rückweiler, Hahnweiler and Leitzweiler bear the tag Auf der Heide, although it is unclear why this is so.

Rohrbach's own name seems to have sprung from the bulrushes (Rohrkolben in German) and reeds (Schilfrohr) that once grew in abundance along the brook (Bach).

This theory is easy to believe, for the lower valley of the Rohrbach is quite marshy and boggy, with soil in which such plants easily take root and grow.

Witnessing this are a number of archaeological finds of things such as gold and silver Roman coins and grave urns, which have been unearthed in the village during building work and in the local fields during digging.

Under Frankish rule, the land was carved up into Gaue, with each headed by a gaugrave (Gaugraf i.e. "Gau count").

The villages of the Pflege (literally “care”, but actually a local geopolitical unit) of Rohrbach had documentary mentions in 1428, 1431 and 1440.

Each year, the Schöffe (roughly “lay jurist”) was obliged to gather in the taxes and fines from the subjects and send them to his superior, the Amtsschultheiß in Berschweiler, or to the Oberamt at Castle Lichtenberg.

Count Gerlach V received from the Bishop of Verdun the Schirmvogtei (roughly “blanket bailiwick”) over the Amt of Wolfersweiler, to which Rohrbach, among other places, belonged.

Shortly thereafter, however, he had to forgo the greater part of his new acquisition, but Wolfersweiler, along with Rohrbach, the Count of Veldenz managed to keep.

Three years later, half of each of the two villages of Rohrbach and Rückweiler, along with their people, interest payments and earnings, were under Count of Sponheim Wolf's ownership.

He in turn sold the rights along with other goods and sources of income for almost 500 Gulden to Count of Veldenz Friedrich.

On 15 October 1571, Count Palatine Johann, in his own, his brother Wilhelm's and his cousin Ruprecht's names, enfeoffed Wolfgang Blick von Lichtenberg with the Veldenz fief, which his parents had owned after Boxberg's death, together with, among other things, shares in the villages of Rohrbach and Rückweiler and tithing rights in Rohrbach.

In 1580 and 1581, Duke Johannes I had some silver prospecting undertaken at “Michaels-Bergwerk” (“Michael’s Mine”) near Rohrbach, to ease his subjects’ poverty.

So, livestock from outside was also allowed to use the meadow, and the Brothers Böschhan, butchers from Baumholder, were given leave to graze their herd there, too.

On 5 October 1620, the Schultheiß of Baumholder, named Eichhorn, issued a report about Rohrbach to the Oberamt in connection with the above dispute over the sheep-pledging arrangement.

This war also took its toll on the local livestock: in 1635, the Imperial general Matthias Gallas conquered the Oberamt of Lichtenberg, leaving only one cow standing.

With Napoleon’s downfall and the Congress of Vienna, Rohrbach and the surrounding area became part of the Duchy of Saxe-Coburg-Saalfeld as the Principality of Lichtenberg.

After the Franco-Prussian War in 1870/1871, some small farmers from Rohrbach moved to the neighbouring Saar area to work in the mines or ironworks.

The men spent the workweek at their jobs away from the village, sleeping in dormitories on site, and coming home only on weekends.

In 1922, Rohrbach was hooked up to the Baumholder district power station, although electricity was, given the financial difficulties at that time, quite dear.

In 1933, Adolf Hitler became German Chancellor, marking the birth of the Third Reich, and on 10 July of that same year, a Nazi named Johann Knop was installed as the head of the municipality of Rohrbach.

On 1 March 1935, the Saarland was returned to German sovereignty, causing much excitement in the local area, as many believed that this event would alleviate unemployment.

Rohrbach families have twice had triplets in recent decades, with one set born in 1984 (Diana, Christina and Jessica) and another in 1997 (Hannah, Marie and Lukas).

The charges in the lower field are canting for the village's name, Rohrbach, which roughly translated means “Bulrush Brook”.

The municipality of Rohrbach was featured on 10 September 2009 on the SWR3 programme Hierzuland, showing its lively village life and clubs.

Over the last few decades, the population figure has been shrinking as young people choose to move away after their studies or apprenticeship, seeing not much in the way of job prospects locally, and greener pastures elsewhere.
