 The problem was settled only after the French Revolution, when Sankt Julian had become Bavarian.Both the County Palatine of Zweibrücken and the Rhinegraviate adopted the Lutheran faith early on in the time of the Reformation.Under the old principle of "cuius regio, eius religio", everybody in Sankt Julian had to convert to Protestantism sometime about 1560, and even today, now that there is freedom of religion, the great majority of Sankt Julian’s inhabitants are Evangelical.
