In the 16th century, as a result of Martin Luther’s Reformation, a new order in religious life came about for the whole Duchy of Palatinate-Zweibrücken, and thereby also for the small village of Blaubach. Worth noting in this era is the rise of fearsome sicknesses, above all, the Plague. In Blaubach, which had so few inhabitants to begin with, 22 persons died in the Plague year 1574 alone; in the Plague year 1597 it was a further 18. Nevertheless, the village did not die right out, for in the years after 1600, roughly two children were being born every year. Perhaps young families had already come and settled in the village. Later Plague epidemics did not affect Blaubach as badly. In the 1588 description of the "Oberamt" of Lichtenberg by the Zweibrücken official Johannes Hofmann, a description of the village’s location also appears, dealing mainly with geographical dimensions.
