During the French Revolution, the French Revolutionary army occupied Mainz in 1792; the Archbishop of Mainz, Friedrich Karl Josef von Erthal, had already fled to Aschaffenburg by the time the French marched in. On 18 March 1793, the Jacobins of Mainz, with other German democrats from about 130 towns in the Rhenish Palatinate, proclaimed the 'Republic of Mainz'. Led by Georg Forster, representatives of the Mainz Republic in Paris requested political affiliation of the Mainz Republic with France, but too late: Prussia was not entirely happy with the idea of a democratic free state on German soil (although the French dominated Mainz was neither free nor democratic). Prussian troops had already occupied the area and besieged Mainz by the end of March 1793. After a siege of 18 weeks, the French troops in Mainz surrendered on 23 July 1793; Prussians occupied the city and ended the Republic of Mainz. It came to the Battle of Mainz in 1795 between Austria and France. Members of the Mainz Jacobin Club were mistreated or imprisoned and punished for treason.
