The "Manifeste Occitaniste" at the beginning of 2013 was defined at that time as setting forth the basic elements of a political force in Occitania, without being a party, with an eye to the French municipal elections of 2014.
Essentially, the "programmatic basis" of the "Manifeste Occitaniste" talked about conservancy and socialization of the Occitan language, regionalism, decentralization and direct democracy, environmental protection, and rejection of the fascism.
The steering committee had the especially difficult role of arbitrating disputed cases, particularly the incorrect requests for authorization of "Bastir!"
candidates were elected in major cities of Occitania as well: in Auch (Henri Chavarrot,[26][27] Benedicte Mello, Nadia Baitiche, Rui Oliveira-Santos),[28] Orange (Anne-Marie Hautant,[29][30][31]) Montauban (Gael Tabarly[32][33]), in Pau, Muret,[34][35][36][37] Villeneuve-sur-Lot, Carmaux, Graulhet.

in Toulouse, east Gascony and south Quercy (French departments of Gers, Haute-Garonne and Tarn-et-Garonne)[45][46] is a success: the historical denomination "Occitanie" wins the citizens consultation organized by the new Regional Council[47][48] to find a name for the new region born from the merger of "Midi-Pyrenees" with the "Languedoc-Roussillon".
The weekend of October 14–16, 2016, during the Constituent Assembly of L'Isle-Jourdain (Toulouse Gascony),[49][50] and following this recognition of the Occitan identity by the French government which agrees to call "Occitanie" one of an administrative regions of the Republic (September 29, 2016),[51] the movement decides unanimously to change "Bastir!"
[52] For the French presidential election of 2017, Jean-Luc Davezac[53][54][55] and several members of "Bastir Occitania" collaborated in the movement "En Marche!"
candidate on the 8th district of Haute-Garonne, the Occitanist candidacy of Jérôme Piques (Occitan Nation Party) in that constituency.
But in January 2019, Bastir breaks with macronism following the Blanquer reform project of the national education which has a negative impact on the teaching of the Occitan language.
Jean-Luc Davezac[68] was chosen by this league "Occitània ecologista e ciutadana" (ecological citizens of Occitania) to lead the list.
On January 15, 2022, "Bastir Occitanie" joins the Federation of United Countries ("Fédération des Pays Unis"), an alliance between five regionalist parties in France.
