and annexed to the Cisalpine Republic on 10 October 1797. In December of the same year, the Bishopric of Basel was occupied and annexed. On 9 December 1797, Frédéric-César de La Harpe, a member of the Helvetian Club from Vaud, asked France to invade Bern to protect Vaud. Seeing a chance to remove a feudal neighbor and gain Bern's wealth, France agreed. By February 1798, French troops occupied Mulhouse and Biel/Bienne. Meanwhile, another army entered Vaud, and the Lemanic Republic was proclaimed. The Diet broke up in dismay without taking any steps to avert the coming storm. On 5 March, troops entered Bern, deserted by her allies and distracted by quarrels within.

Leading groups split into the Unitaires, who wanted a united republic, and the Federalists, who represented the old aristocracy and demanded a return to cantonal sovereignty. Coup-attempts became frequent, and the new régime had to rely on the French to survive. Furthermore, the occupying forces plundered many towns and
