The village lies at the foot of the 536 m-high Herrmannsberg at an elevation of some 270 m above sea level on the local thoroughfare.

The Sachsbach rises some 2 km up from the village of Elzweiler near the Schneeweiderhof and empties into the river Glan near Glanbrücken.

Owing to only slight population growth, the original built-up area has not significantly spread outwards.

The border's exact 1355 alignment, however, cannot be fully gathered from this oldest surviving description, making much of the matter guesswork.

What can be gathered is that the border ran along the brook down from Welchweiler as far as the forks with the Sachsbach, whence it doubled back upstream into the woods.

Apart from the mention of the “Elzweiler Bach” (that is, the Sachsbach) in this 1355 border Weistum (a Weistum – cognate with English wisdom – was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times), the first documentary mention of the village itself is found in a 1364 document, according to which Count Heinrich II of Veldenz transferred the tithes from the villages in the Amt of Altenglan-Brücken, and later the Niederamt of Ulmet, to the newlywed comital couple Lauretta and Heinrich.

[6] According to Johannes Hofmann's 1588 description of the Amt of Lichtenberg, the border between the Grumbacher Gebiet and the County Palatine of Zweibrücken ran between the villages of Elzweiler and Welchweiler.

In this description, Elzweiler is described as a Hof (“estate” or “farm”), thereby giving a clue as to the village's very small size at that time.

Thereafter, Elzweiler remained with the County Palatine until its downfall after French Revolutionary troops began their occupation.

[7] During the time of French rule from 1801 to 1814, Elzweiler lay in the Department of Mont-Tonnerre (or Donnersberg in German), whose seat was in Mainz, in the Arrondissement of Kaiserslautern and in the Canton of Wolfstein.

After the French had withdrawn in 1814 and Napoleon had been defeated at Waterloo, the Congress of Vienna awarded the Palatinate to the Kingdom of Bavaria.

By the time of the 1933 Reichstag elections, after Hitler had already seized power, local support for the Nazis had swollen to 83.6%.

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

Since the end of the Second World War, when the Palatinate was split off from Bavaria, the village has lain in the then newly founded state of Rhineland-Palatinate.

Originally part of the Bürgermeisterei (“Mayoralty”) of Horschbach, in the course of the 1968 administrative restructuring in Rhineland-Palatinate, Elzweiler was grouped into the Verbandsgemeinde of Altenglan.

It can be assumed that there were two farms, whose occupants worked land practically throughout what is now the municipal area, and to whose households belonged not only the farmers and their families, but also menservants and maidservants.

Nevertheless, for 1477 and 1478, fifteen villagers who owed taxes were named, leading to the conclusion that the population must have shrunk drastically sometime about the beginning of the 16th century, perhaps as a result of an epidemic.

After the placename Elzweiler appeared in the 1365 Veldenz document, the village may at least for a time have belonged to the Ulmet parish.

The arms have been borne since 7 April 1975 when they were approved by the now defunct Rheinhessen-Pfalz Regierungsbezirk administration in Neustadt an der Weinstraße.

The current armorial design combines the anchor seal mentioned by Hupp (which apparently can no longer be confirmed) and the lion charge borne by the village's former lords.

[19] In 1970, Elzweiler's occupational structure broke down thus: agriculture and forestry 6.3%, manufacturing 41%, trade and transport 8.3%, service industries 10%, retired 34%.
