Landgraviate of Hesse-Darmstadt
In 1714 the County of Erbach, which ruled the Odenwald area for 500 years, was forced to sell Balkhausen as an accessory to the "Amt Seeheim-Tannenberg" to the Landgraviate of Hesse-Darmstadt due to financial difficulties. It then remained in Hesse or its predecessor states until today.
