The villages belonged to various ecclesiastical and secular rulers, but a great deal of the current municipal area came to be part of the County of Solms as time went by, through estate division, pledges and feuds.

Among the four local powers, namely the Landgraves of Hesse, the Electors of Mainz, the Free Imperial City of Wetzlar and the Counts of Nassau, the political climate was seldom calm.

Bischoffen earned itself special importance with the building of the Cologne-Leipzig commercial road, along whose route the Aar-Salzböde railway and Federal Highway (Bundesstraße) B 255 were later built.

With the onset of the 19th century, the area was once again divided: Bischoffen, Niederweidbach and Roßbach passed to the Grand Duchy of Hesse, and Ahrdt and Mudersbach to the Kingdom of Prussia.

Up until municipal reform in 1972, the community's outlying centres belonged to the Biedenkopf district, but given their location and economic orientation, they were assigned to the new Lahn-Dill-Kreis.

Bischoffen's civic coat of arms might heraldically be described thus: A bend wavy argent, above, in azure the crook of a bishop's crozier sinister Or, below, in vert an inverted scallop shell Or.
