Quite early on, a mediaeval regular route linking Landstuhl to Trier following the nearby ridge running parallel to the brook was established as a roadway.

Still in its planning stages is an expansion of a disused rural pathway which is to be repurposed as an educational nature walk with a dry stone wall, featuring various portions of its length in different conditions to host a variety of flora and fauna for visitors to observe.

On the peak of the Potschberg, now been stripped away by stone quarrying, the remnants of a mountain sanctuary from the 2nd or 3rd century AD (Roman period) were found in 1965.

Quite a few coins from the first to the fourth centuries A.D. have been unearthed locally as a result of land surveys along with water pipes and a 5 cm-tall 2nd-century bronze figure of the god Mercury.

Unearthed here were wall remnants, waste, clay waterpipes and pieces of little heating pipes, leading investigators to conclude that it was a settlement from the 2nd and 3rd centuries.

The site proved to house a remarkably large complex of Roman structures over what was a possible temple zone and a villa rustica, accompanied by many outbuildings.

At that time, Jettenbach belonged to the extensive area of the Reichsland ("Imperial Land") near Kaiserslautern, which was already subdivided into separate court districts (Gerichte).

In the letters patent bestowing these holdings upon Count Friedrich III, however, Jettenbach was part of the combined Amt of Reichenbach and Deinsberg, and was split into Ober-Gittenbach and Nieder-Gittenbach.

After the Counts of Veldenz died out in 1444, the village, along with the rest of the Amt of Reichenbach, passed to the Dukes of Palatinate-Zweibrücken.

Due to various factors, it appears, however, that the village was largely destroyed, and that three quarters of the local population fell victim to the war or consequent disease.

From his death arose a dispute between the Duchy of Palatinate-Zweibrücken and the Electorate of the Palatinate as to who was his rightful heir and inheritor of his former domains.

In a compromise between the two princely houses competing to inherit the locality, it was agreed that, from 1733, Jettenbach would be ceded permanently to the Electorate of the Palatinate.

From the turn of the nineteenth century, French Revolutionary intervention swept away the arrangements of historical ruling class and with it their traditional lordship over Jettenbach.

Instead, Jettenbach had to endure a period characterised by the influx of troops on the march, their demands for supplies and their presence when stationed or billeted in the village.

In Jettenbach, candidate-teacher, Jettenbach-born Ludwig Heinrich Hauber promoted his ideas of Palatine separatism and freedom taking leave from his post in Katzweiler to dedicate himself to the cause.

These volunteers agreed on the precaution that at the first sign of danger they would return to their homes, promptly doing so as the Prussians drew nearer.

Their added buying power and consequent upsurge in building activity was primarily responsible for an improved economic outlook.

By the early 1950s, a shift in Jettenbach's economic foundations saw increasing numbers employed beyond the village with new jobs at places such as the United States Armed Forces in Kaiserslautern, Ramstein, and Miesau.

In November 2003, the Minister of Environment and Forests, Margit Conrad, awarded mayor Bernd Ginkel a special prize for "the municipality’s model ecological performance".

This was based mainly on the forward-looking heating plants (wood pellets and woodchips), the solar and photovoltaic complexes, and clear strides in local nature conservation in the municipality.

[13] The first syllable of the municipality's name, Jettenbach, refers to perennial ryegrass (Lolium perenne), which still grows along the village brook today.

While it is known that Zeißweiler lay north of Jettenbach at the foot of the Trautelsberg – at least according to researcher Ernst Christmann – its exact location is also unknown.

[14][19] The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:[20] The Quereinhaus at Honiggasse ("Honey Lane") 1 is described elsewhere as a West Palatine farmhouse with a single roof ridge (Einfirstbauernhaus).

The residential wing's upper floor is built with exposed timber framing, a decorated groundsill, several chest- and neck-high railings and an oriel window.

The Musikantenhaus at Hauptstraße ("Main Street") 66 is typical in construction for a house belonging to the travelling musicians of yore, especially for the inclusion of a dormer-like gable at the front.

[21] Jettenbach's church's patronal festival (Kermis) is known locally as the Kerwe, and is held on the third Sunday in August, and is, by extension, a celebration for the whole community.

Only from the 1950s were great Prunksitzungen (Sessions of the "parliament" of the "Empire of Narren", that is, fools) and masquerade balls held, although the latter barely survive.

Specialized crops are no longer raised in Jettenbach, although the village is said to have been a main growing centre for rapeseed in the Landcommissariat of Kusel in the years after 1820 (4 226 hl in 1826).

It was only in the 1880s that some of these local musicians became bold enough to visit the United States, but before the turn of the century, there were few parts of the world where the Wandermusikanten had not trodden.

In 1971, the Jettenbach and Rothselberg schools for grade levels 1 to 4 were combined, with Eßweiler, Hinzweiler and Oberweiler im Tal joining in 1988.
