Austria via Napoleonic France to the Helvetic Republic, was briefly a separate canton of the Helvetic Republic (the canton of Fricktal) under a Statthalter ('Lieutenant'), but on 19 March 1803 (following the Act of Mediation) was incorporated into the canton of Aargau. The former cantons of Baden and Fricktal can still be identified with the contemporary districts – the canton of Baden is covered by the districts of Zurzach, Baden, Bremgarten, and Muri (albeit with the gains and losses of 1803 detailed above); the canton of Fricktal by the districts of Rheinfelden and Laufenburg (except for Hottwil which was transferred to that district in 2010). Chief magistracy The chief magistracy of Aargau changed its style repeatedly: first two consecutive Regierungsstatthalter : April 1798 – November 1801 Jakob Emmanuel Feer (1754–1833) 1802–1803 Johann Heinrich Rothpletz (1766–1833) Presidents of the Government Commission 10 March 1803 – 26 April 1803 Johann Rudolf Dolder (1753–1807) 26 April 1803 – 1815 a 'Small Council' (president rotating monthly) annual Amtsbürgermeister 1815–1831 annual Landammänner since 1815 Jewish history in Aargau In the 17th century, Aargau was the only federal condominium where Jews were tolerated.

They imposed special taxes on peddling and cattle trading, the primary Jewish professions. The Protestant occupiers also enjoyed the discomfort of the local Catholics by the presence of the Jewish community. The Jews were directly subordinate to the governor; from 1696, they were compelled to renew a letter of protection from him every 16 years. During this period, Jews and Christians were not allowed to live under the same roof, neither were Jews allowed to own land or houses. They were taxed at a much higher rate than others and, in 1712, the Lengnau community was "pillaged." In 1760, they were further restricted regarding marriages and procreation. An exorbitant tax was levied on marriage licenses; oftentimes, they were outright refused. This remained the case until the 19th century. In 1799, the Helvetic republic abolished all special tolls, and, in 1802, removed the poll tax. On 5 May 1809, they were declared citizens and given broad rights regarding trade and farming.
