In 1323, Eberhard III died without leaving a surviving son and so the Lordship of Gedern passed to Conrad V of Trimberg and Gottfried V of Eppstein.
In 1356, Charles IV, Holy Roman Emperor granted the House of Trimberg market rights in Gedern.
After the House of Eppstein divided up its lands in 1433, Gedern passed to the Eppstein-Königstein line.
On Eberhard IV's death in 1535, Gedern and its associated County of Königstein passed to the Counts of Stolberg.
However, with the adoption of the sovereignty rights outlined in the Treaty of the Confederation of the Rhine, that line had to cede it to Hesse-Darmstadt.
