Limburg-Isenberg was a medieval County of Germany, based in the County of Limburg and the County of Isenberg. Although typically Count Frederick I of Isenberg and Altena was implicated in the murder of Engelbert of Berg and his lands were stripped. His son and heir Count Frederick II never ruled any lands. It was Theodoric I who regained some territory for the family in 1242 after an appeal to the Holy Roman Emperor. Both the Counties of Limburg-Hohenlimburg and Limburg-Styrum were partitioned from the territories of the County. In 1301 what was left of the county was partitioned between Limburg-Hohenlimburg, Cologne and Marck.
It should be mentioned that all three counts of Limburg-Isenberg ruled as "Altena-Isenberg". The name "Limburg" in the name of this state and its successors derives from the descent of the Counts from the Dukes of Limburg.
