Like all villages in the area, Föckelberg, too, saw a great deal of suffering in the 17th century's wars, namely the Thirty Years' War and French King Louis XIV's wars of conquest. Details of the misfortunes wrought upon Föckelberg itself in these wars are unknown, but something does survive from that time: a Huberweistum (a Huber was a farmer who owned a whole hide of land, while a Weistum - cognate with English wisdom - was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times) from the municipality of Föckelberg. The Föckelberg Weistum was set down in writing in 1671. The first part deals with the redefinition of the hides (fields) within municipal limits, and then the document goes on to lay down the rules of conduct for the farmers. It was presented to the farmers each year on Saint Thomas's Day (then 21 December) on the occasion of the walking of the fields. In 1543, Duke Wolfgang of Zweibrücken transferred to his uncle Ruprecht holdings so that he could found his own county palatine. Belonging to this were Veldenz on the Moselle, the Ämter of Lauterecken and Reichenbach, the Remigiusberg and later also Lützelstein (now called La Petite-Pierre) in Alsace. The residence town was at first Lauterecken. The line of the Counts Palatine of Veldenz-Lauterecken-Lützelstein died out in 1694, and the County Palatine of Veldenz passed in 1717, after disagreements between Electoral Palatinate and Palatinate-Zweibrücken, to Electoral Palatinate, although this was only made permanent in 1733 by the Mannheim Treaty of Succession. In line with this development, Föckelberg belonged from 1344 to 1444 to the old County of Veldenz, from 1444 to 1543 to the Duchy of Palatinate-Zweibrücken, from 1543 to 1694 to the new County Palatine of Veldenz, and beginning in 1733 to Electoral Palatinate. In 1788, Föckelberg was mentioned in Goswin Widder's Geographische Beschreybung der Kurpfalz (Geographical Description of Electoral Palatinate). This says, among other things: Föckelberg is a midsize village at the Potzberg. … The population of this village is made up of 39 families, 176 souls, the buildings of 30 private and 3 common houses, the municipal area of 501 Morgen in cropfields, 110 Morgen in meadows and 406 Morgen in woodland. Found on the Potzberg is a quicksilver mine, called Elisabethengrube, from which in the year 1477, 2,520 pounds of quicksilver was mined. The common houses to which Widder referred (gemeine Häuser in the original German text) may have been buildings available for use to all villagers, for instance, the herdsman's house or the bakehouse. Electoral Palatinate rule came to an end when French Revolutionary troops marched into Germany in the late 18th century.
