PT was formed in July 2012 as a split, led by former regional minister Silvano Grisenti, from the Union for Trentino (UpT).

Mosna won a 19.3% of the vote, coming a very distant second from Ugo Rossi of the Trentino Tyrolean Autonomist Party, who was supported by the autonomist/centre-left coalition and garnered a landslide 58.1%.

[6] However, PT emerged as the fourth largest political force of Trentino, by winning 9.0% of the vote (the UpT got 13.3%)[6] and four provincial councillors plus Mosna, who was elected as best-placed defeated candidate.

[15] In April the PT signed a federative pact with the Populars for Italy (PpI), a minor Christian-democratic party represented in Parliament.

[21][22][23] In the election, Fugatti was re-elected and the autonomist joint list obtained 8.2% of the vote and three councillors, including Tonina, who would continue as provincial minister.
