(† 1410) and her husband Philipp I, Count of Nassau-Weilburg, Kirchheimbolanden and the entire Sponheim-Bolander family property finally fell to the Nassau House, which owned it until the end of the feudal period. Early modern age Charles August, Prince of Nassau-Weilburg moved his residence from Weilburg to Kirchheim in 1737. Charles Christian, Prince of Nassau-Weilburg temporarily owned his own infantry regiment (1755–1759) in Mannheim with the Elector of the Electoral Palatinate and was temporarily general of the Netherlands, where he was governor. Frederick William, Prince of Nassau-Weilburg (1788–1816) left the city in 1793 because of the French Revolution and went to Bayreuth. This ended the time as the royal seat for Kirchheimbolanden, then only called Kirchheim. It experienced its greatest heyday under Prince Charles August (1719–1753) and especially under Carl Christian (1753–1788) of the House of Nassau-Weilburg and his rich, clever and musical wife Princess Carolina of Orange-Nassau. From the 19th century After 1792, French revolutionary troops occupied the region and after the Treaty of Campo Formio (1797), annexed the left bank of the Rhine. From 1798 to 1814, Kirchheim belonged to the French department of Donnersberg and was the main town (chef-lieu) of the canton of the same name. Due to the agreements made at the Congress of Vienna (1815) and an exchange contract with Austria, the region became part of the Kingdom of Bavaria in 1816. From 1818, Kirchheim was the seat of a land commissioner in the Bavarian Rhine circle. When the Rhenish Hessian Legion hurriedly evacuated Kirchheim from a Prussian overwhelming power during the Palatinate uprising on June 14, 1849, Palatine militants remained in the palace garden without notification. In the battle of Kirchheimbolanden in the presence of the Prince of Prussia, 17 militants were killed. From 1939, the place was part of and administrative seat of the district of the same name. After the Second World War, Kirchheimbolanden became part of the then newly formed state of Rhineland-Palatinate, within the French occupation zone. In the course of the first Rhineland-Palatinate administrative reform, the city moved in 1969 to the newly formed Donnersbergkreis and its seat; three years later, Kirchheimbolanden was incorporated into the also newly created community of the same name.
