[1][2] The group was formed on 17 October 2018, led by co-presidents Bertrand Pancher from Meuse and Philippe Vigier from Eure-et-Loir.

Prior negotiations between Corsican nationalist deputies, Olivier Falorni and François Pupponi had failed at the beginning of the 15th legislature.

At its founding, the group defined itself as in the "minority", refusing to register as either being in the majority or in opposition to the government.

Following the 2022 legislative election, the group was central in a March 2023 attempt at dismissing the minority government of Prime Minister Élisabeth Borne through a motion of no confidence presented by Pancher and defended in front of Parliament by Charles de Courson.

According to Laurent Panifous, the parliamentary group is likely to continue past 2024 should a sufficient number of incumbent deputies be re-elected.
