In January 2011, Zuncheddu left the party in order to join Independence Republic of Sardinia (iRS).[7][8] This caused a major upheaval within the party, which was left without representation in the Regional Council.[9] However, the party pushed back and, in the 2014 regional election, it won 2.6% of the vote and two regional councillors.[10]
In the 2019 regional election the party formed, outside big coalitions, a joint list with the iRS and Sardigna Natzione Indipendentzia (SNI) named "Self-determination"[11] and obtained 1.9% of the vote. As a result, the party was no longer represented in the Regional Council. In June 2021, during a party congress, Lucia Chessa and Natacha Lampis were elected secretary and president, respectively.[12]
In the 2024 regional election Chessa ran as a stand-alone candidate, obtaining 1.0% of the vote, while the party got 0.6% of the vote and no seats in the Regional Council.

È a fianco dei sardi nella lotta per l’autodeterminazione e la sua liberazione, per costruire la Nazione Sarda, la sua Sovranità, la sua Indipendenza in una Europa di popoli e nazioni solidali e uguali. Siamo un movimento identitario, solidale, progressista, antifascista, popolare e di sinistra, quindi anticolonialista e figlio del miglior azioniamo, che crede nella democrazia partecipata e ne fa strumento della propria azione politica per la Liberazione, l’Autodeterminazione, la Sovranità e l’Indipendenza del popolo sardo.
