The Cisrhenian Republic () was a planned client state during the French Revolutionary Wars in 1797 on the Left Bank of the Rhine under occupation by France, where the Coup of 18 Fructidor caused a decision to annex the area instead. History At the beginning of the War of the First Coalition, in 1792, French revolutionary troops conquered the Palatinate region and occupied the cities of Mainz, Speyer, and Worms. They terminated the centuries-long reign of the local nobility and clergy, which met with approval among broad sections of the public. A German Jacobin Club was established at Mainz in October to promote the export of revolution in the lands of the Holy Roman Empire together with the occupying forces.

On 13 April 1797, at the suggestion of General Hoche, the Directory resolved upon the establishment of a on the west-Rhenish territories of the Electorates of Trier, Mainz and Cologne, of the Electoral Palatinate, the duchies of Arenberg and Jülich-Berg, the free cities of Aachen and Cologne, and several smaller counties and lordships. Together the Rhenish lands from Cleves up to Bingen were planned to be combined into a republic under the rule of General Hoche as 'Protector'. The republican movement was again gaining a substantial following, at least in Rhenish cities such as Bonn or Koblenz.
