Leitzweiler – older forms of the name were Leideßweiler, Leydesweiler or Laitzweiler – was certainly very small at this time, not so much a village as a farm, and with few inhabitants.

A 1539 agreement between the Oberamt of Lichtenberg and the Lords of Oberstein set forth clearly that authority in civil, personal and practical matters lay with the Duchy of Palatinate-Zweibrücken.

This one set forth that authority in civil, personal and practical matters lay with the Lordship of Wertenstein, but high jurisdiction was reserved to Palatinate-Zweibrücken.

Among other things dealt with in the agreement was the question of appearances at the weekly market in Baumholder by the villagers of Leitzweiler.

The new agreement rectified this, and after it came into force, failure to appear at Baumholder Market was no longer punishable, as long as a Wertenstein official could show a certificate indicating that there was compulsory labour to be done that day.

The Thirty Years' War (1618–1648) brought plundering, devastation and destruction to Leitzweiler and its surrounding area.

In 1667, Lorraine finally managed to gain control over the Lordship of Wertenstein, thus ending the centuries-long squabbles with Oberstein or Palatinate-Zweibrücken.

It seems that the French soldiers were to have burnt Eitzweiler, another village a few kilometres away, today a constituent community of Freisen in the Saarland.

The Rhine's left bank was thus freed of French rule, and by a treaty concluded in May 1814, it was placed under a joint Imperial-Royal Austrian and Royal Bavarian “State Administrative Commission” (Landesverwaltungskommission).

Representatives from Europe's powers gathered in 1814 and 1815 at the Congress of Vienna to decide the Continent's political shape in the post-Napoleonic era.

In April 1815, great parts of the now leaderless lands out of which the French had been driven passed to Prussia.

The newly formed cantons of Sankt Wendel, Grumbach and Baumholder – within which lay Leitzweiler – were, however, given by the concluding act of the Congress to the Duchy of Saxe-Coburg-Saalfeld as compensation for having helped the allies in the Napoleonic Wars.

In 1832, the Hambach Festival was held, attended by 20,000 people who demonstrated for freedom, democracy, and national unity.

At the same time, riots broke out in Sankt Wendel, leading the Duke to decide to sell the Principality of Lichtenberg to Prussia.

The agreed price was 2,100,000 Thaler, and thus, in 1834, Leitzweiler remained a border village, but now in Prussian territory, while the Weiersbach side was, as it had been before, the Principality of Birkenfeld in the Grand Duchy of Oldenburg.

As a result of Germany's defeat in the First World War and the subsequent 1919 Treaty of Versailles, the Sankt Wendel district was split: 26 of the 94 municipalities within it were grouped into the Saar, a League of Nations mandate.

Oldenburg and Prussia still existed in one form or another right through Imperial and Weimar times, but the Third Reich put an end to the former in 1937 by merging it with the latter.

Prussia itself was abolished as any kind of political entity after the Second World War with the onset of Allied occupation.
