Langenthal's name cropped up for the first time in 1322 and it refers to a narrow dale that stretches along a watercourse. Langenthal was until the 18th century united with neighbouring Monzingen, to whose market business it had been attached. No later than the 13th century, it belonged to the Counts of Sponheim, who had granted some knightly families the court and the tithes. In 1708, Langenthal passed along with some other places to Electoral Palatinate, and within that to the Amt of Böckelheim. In 1798, after French Revolutionary troops had overrun the German lands on the Rhine’s left bank, it was assigned to the Mairie of Monzingen. The court to which Langenthal was subject, called the Friedensgericht, had its seat in Sobernheim. This was converted into an Amtsgericht in 1879. After the Napoleonic Wars had ended and Napoleon had been driven out and defeated, the Congress of Vienna assigned this administrative region to the Kingdom of Prussia. Monzingen remained the seat of a Bürgermeisterei within the newly formed Kreuznach district, to which Langenthal also belonged. In the course of administrative restructuring in Rhineland-Palatinate after the Second World War, Langenthal found itself grouped into the Verbandsgemeinde of Bad Sobernheim.
Population development
Langenthal's population development since Napoleonic times is shown in the table below. The figures for the years from 1871 to 1987 are drawn from census data:
Religion
As at 30 September 2013, there are 99 full-time residents in Langenthal, and of those, 57 are Evangelical, 29 are Catholic and 13 either have no religion or will not reveal their religious affiliation.
Politics
Municipal council
The council is made up of 6 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman.
The German blazon reads: Im Schild in Rot ein silberner Wellenschrägbalken, begleitet vorne von einem silbernen sechsspeichigen Rad, hinten von einer silbernen Kapelle. The municipality's arms might in English heraldic language be described thus: Gules a bend wavy between in dexter base a wheel spoked of six and in sinister chief a chapel, all argent. The wavy bend symbolizes the long Hoxbach and Gaulsbach valley, on which the village lies. The charge on the sinister side, the chapel, is the village church, which was built towards the end of the 15th century, expanded in the 16th century and renovated in 1954. Even today, both the Evangelical and the Catholic communities have rights to this house of worship. The other charge, the Wheel of Mainz on the dexter side, was taken from Monzingen’s arms, as Langenthal, first mentioned in 1322, shared a common municipal area with Monzingen until the 17th century and thereby had much the same history as its neighbour.
