Trentino Tyrolean Autonomist Party

The Trentino Tyrolean Autonomist Party (Italian: Partito Autonomista Trentino Tirolese, PATT) is a regionalist, autonomist, Christian-democratic and centrist political party in Trentino, Italy. The PATT, heir of the Trentino Tyrolean People's Party, is the unofficial counterpart of the South Tyrolean People's Party (SVP), active in South Tyrol. The two are members of the European People's Party (EPP) and usually contest general and European Parliament elections together. Simone Marchiori is the party's current secretary, Mauro Verones president and Franco Panizza honorary president. The PATT has led the provincial government with Carlo Andreotti in 1994–1999 and Ugo Rossi in 2013–2018, as well as the regional government with Andreotti in 2002–2004 (when the office of president was not rotational) and again with Rossi in 2014–2016.

The party has had a diverse membership and, as a result, frequently experienced internal conflicts and splits. Centrists like Marchiori, Panizza and Rossi supported the centre-left coalition with the Democratic Party and the Union for Trentino in 2002–2018. Andreotti, Franco Tretter, Giacomo Bezzi and, lately, Walter Kaswalder, expelled in 2017, held a more conservative (and traditional) position, that resonated well with the party's grassroots. However, the alliance with the centre-left was broken in the run-up to the 2018 provincial election. The party later aligned with the centre-right coalition and especially with the alike autonomist Lega Trentino for the 2023 provincial election; in the process, Rossi switched to the centrist Action party in 2021, while several centre-left figures, notably including Luigi Panizza and Dario Pallaoro, left the party and joined Autonomy House.
