Pugliesi-Conti was elected as a deputy to the National Assembly in 1910 and openly declared his support for the republic, resulting in numerous monarchist Bonapartists challenging him for his seat in 1914.

In 1943 Paoli was deposed by communist members of the resistance and was exiled to Laghouat in French Algeria, although was allowed to return to France following the war.

The CCB allied itself with moderates and radicals and managed to elect its candidate, Nicéphore Stephanopoli de Comnene, as Mayor of Ajaccio.

In 1983, the CCB was forced to ally itself with the Union for French Democracy (UDF) and Rally for the Republic (RPR) in a list where it no longer held a majority of seats in order to stave off a left-wing victory in Ajaccio.

Shortly after, the party's support began to collapse after a member of the House of Bonaparte, Charles, Prince Napoléon, announced he would enter local political life, endorsing the mainly centre-left Régions et Peuples Solidaires coalition for the 1994 European Parliament election.

In 2013/2014, the party was re-activated under the leadership of André Villanova, and began attempting to reconcile with the more liberal views of contemporary politics in Ajaccio, supporting the list of UMP member Laurent Marcangeli in the 2014 Corse-du-Sud municipal elections.

For the 2022 French legislative election, the party, along with the incumbent presidential coalition, endorsed Marcangeli's candidacy in Corse-du-Sud's 1st constituency as a member of Horizons.
