The party emerged in January 2013 as a split from the Valdostan Union (UV), similarly to what had happened forty years before with the historical UVP.

Over the years the UV had become more acquainted with the centre-right and this caused the exit of three regional councillors (Luciano Caveri, Laurent Viérin and Andrea Rosset), who launched the UVP on 4 January 2013.

[14][15] Caveri, Brédy and Gérandin later launched an alternative centre-left party named Mouv',[16][17] which would be later joined by Rosset and two dissident regional councillors of the Five Star Movement (M5S).

[29][30] However, in December the government was replaced by a new one led by Antonio Fosson (PNV), at the head of a coalition composed of the UV, the UVP, ALPE, SA and PNV:[31][32][33] Viérin was appointed minister of Tourism, Sport, Commerce, Agriculture and Cultural Heritage, while Bertschy minister of European Affairs, Labour Policies, Social Inclusion and Transports.

[34] In February 2019 Giuliano Morelli, whose political program featured the formation of a joint autonomist party, was elected as UVP's new president.
