County of Isenburg

From Wikipedia, the free encyclopedia
Isenburg (pink, right) and Lower Isenburg (pink, left) around 1400

The County of Isenburg was a region of Germany located in southern present-day Hesse, located in territories north and south of Frankfurt. The states of Isenburg emerged from the Niederlahngau (located in the Rhineland-Palatinate), which partitioned in 1137 into Isenburg-Isenburg and Isenburg-Limburg-Covern. These countships were partitioned between themselves many times over the next 700 years.

House of Isenburg

[edit]
Ruins of the Castle at Isenburg (Lower Isenburg)

The House of Isenburg was an old aristocratic family of medieval Germany, named after the castle of Isenburg in Rhineland-Palatinate. Occasionally referred to as the House of Rommersdorf before the 12th century, the house originated in the Hessian comitatus of the Niederlahngau in the 10th century. It partitioned into the lines of Isenburg-Isenburg and Isenburg-Limburg-Covern in 1137, before partitioning again into smaller units, but by 1500 only the lines of Isenburg-Büdingen (in Upper Isenburg) and Lower Isenburg remained. In 1664 the Lower Isenburg branch died out. The Büdingen line continued to partition, and by the beginning of the 19th century the lines of Isenburg-Büdingen, Isenburg-Birstein, Isenburg-Meerholz and Isenburg-Wächtersbach existed. Today still exist the (Roman Catholic) princes of Isenburg (at Birstein), the (Lutheran) princes of Ysenburg (at Büdingen and Ronneburg) and the (Lutheran) counts of Ysenburg-Philippseich.

Isenburg, the original countship was divided upon the death of Count Rembold II in 1137 into:

Principality of Isenburg

[edit]
Coat of Arms of the Principality of Isenburg

It was not until 1806 that there was a state called simply "Isenburg". When the Holy Roman Empire was defeated by Napoleon of France in that year, the empire was abolished and the Confederation of the Rhine was established amongst the various German states. As an incentive to join the Confederation, it was stated that any state which joined could mediatise their neighbours. Prince Charles of Isenburg-Birstein joined the Confederation and was granted the mediatized Isenburgian Countships of Isenburg-Büdingen, Isenburg-Meerholz, Isenburg-Philippseich, and Isenburg-Wächtersbach. His Principality was renamed to Isenburg.

The Principality continued under the rule of Prince Charles through the Napoleonic era, but was mediatised by Austria in December 1813, at the insistence of King Frederick William III of Prussia, who was angered that Isenburg had raised a regiment for French service by recruiting Prussian deserters and vagabonds.[1] Isenburg was one of only three original member princes of the Empire to be mediatized at the end of the Napoleonic era (the others being Leyen and prince-primate Dalberg, Prince of Aschaffenburg). This decision was confirmed at the Congress of Vienna. The lands of the principality were divided between the Grand Duchy of Hesse-Darmstadt and the Electorate of Hesse-Kassel (or Hesse-Cassel).
