1914 and that Protestant Sunday services were held locally up until the same date. Constituent communities In July 1972 the communities of Friedrichsdorf, Seulberg, Köppern and Burgholzhausen merged to form the town of Friedrichsdorf/Taunus. Köppern Köppern had its first documentary mention in 1269. At this time, Buchard von Printsac was given in fief a watermill at "coppern" by Count Gerhard von Eppstein. Linen weaving and brickmaking were for a long time, next to farming, the most important economic activities. Later came hatmaking and tanning. In 1901, the Waldkrankenhaus ("Forest Hospital"), which still stands today (as the Fachklinik für Psychiatrie und Psychotherapie, or Specialized Clinic for Psychiatry and Psychotherapy) was founded by Dr. Emil Sioli from Frankfurt. Köppern has a street hockey team, trained by, among others, professional hockey player Ingo Schwarz, who plays for Rote Teufel Bad Nauheim.

With the Huguenots in Friedrichsdorf there was brisk trade. In a somewhat less cheerful chapter in Seulberg's history, there were witch trials in the 17th century which resulted in 31 women being put to death.

After amalgamation, a new coat of arms was created in 1975, taking the newly amalgamated parts of town into account. It might heraldically be described thus: Party per saltire, above, in azure a rose argent, dexter in argent a four-spoked wheel gules, sinister in argent a horseshoe gules, below, in gules a tower Or. The silver rose charge has been kept, although now there is only one instead of a ring of nine. The red stylized wheel stands for Köppern and the red horseshoe
