 While in the new territorial order arising from the Congress of Vienna the old Rhinegravial villages on the Glan’s left bank were grouped into the Principality of Lichtenberg, a newly created exclave of the Duchy of Saxe-Coburg-Saalfeld (which as of 1826 became the Duchy of Saxe-Coburg and Gotha), Sankt Julian, Obereisenbach and Eschenau were excepted from this transfer and grouped into the Kingdom of Bavaria in 1817 as part of an exchange against a village in the Oster valley.Sankt Julian at first became the seat of a "Bürgermeisterei" ("mayoralty") for these three villages, and administratively amalgamated with it in this context was neighbouring Obereisenbach.The merged municipality was called Sankt Julian-Obereisenbach.
