For the 2011 general election, Eusko Alkartasuna, Alternatiba and their allies formed a new alliance, under the name Amaiur, along with Aralar, previously part of Nafarroa Bai, and other abertzale (i.e., Basque nationalist) groups.

The heads of the coalition list for Álava and Gipuzkoa were, respectively, the spokesperson for the STEE-EILAS union Belén Arrondo and the University of the Basque Country professor Xabier Isasi.

[15] Also on Álava's list were the member of the nationalist left Hasier Arraiz, the Bildu councilor in Amurrio Eva Blanco, the lawyer Julen Arzuaga and the Aralar deputy Igor López de Munain.

With a view to these elections but on the occasion of the World Economic Forum in Bilbao,[17] the coalition held an international rally in that city on 2 March 2014, with the participation of political groups such as Sinn Féin, Syriza, Die Linke, the Left Bloc of Portugal and the BNG, among others.

After obtaining the seat, Josu Juaristi joined the latter group, although he announced that he would also maintain "a priority relationship" with the Greens–European Free Alliance, since the latter has political formations that defend his right.

Three of these parliamentarians were in turn members of EA (Maiorga Ramírez, Miren Aranoa and Esther Korres), three of Sortu (Adolfo Araiz, Bakartxo Ruiz and Dabid Anaut) and two of Aralar (Asun Fernández de Garaialde and Xabi Lasa).

The counselors of the Government of Navarre María José Beaumont (Presidency, Public Service, Interior and Justice) and Isabel Elizalde (Rural Development, Local Administration and Environment) were elected at the proposal of EH Bildu.

After the new call for elections in 2016, EH Bildu renewed the electoral lists, but failed to improve its results by obtaining 184,092 votes (0.77%) and two deputies: Oskar Matute for Biscay and Marian Beitialarrangoitia for Gipuzkoa.

On 17 June 2017, EH Bildu was refounded as a permanent political structure to provide itself with its own bodies with executive capacity and open itself to the activism of independents, leaving behind the classic party coalition formula.

[34][35] However, a critical segment belonging to Eusko Alkartasuna, led by Maiorga Ramírez and supported by its founder Carlos Garaikoetxea, opposed what they considered the marginalization of their party within EH Bildu in the face of the preeminence of Sortu.

In 2023, a complaint was filed by Covite over the inclusion of several candidates who had been convicted of belonging to and collaborating with ETA among the more than 300 EH Bildu lists for the municipal elections in the Basque Country and Navarre.

Seven of these, who especially stood out for having been convicted in a summary process with fatalities, announced that they would resign from their positions if they were elected to show their commitment to coexistence and peace, and this took effect after several of them managed to win.

Although Covite called this withdrawal a victory, the controversy was fueled by the request to outlaw EH Bildu presented by Vox, the president of the Community of Madrid Díaz Ayuso and the Dignidad y Justicia association, which was rejected by the Prosecutor's Office.

The agreement included other commitments related to "the consolidation of a scenario of non-violence with guarantees and the reestablishment of democratic minimums", the Basque language, the fight for equality between women and men, defense of education, the field of youth, in favor of internationalism and against racism and xenophobia.

EH Bildu defines itself ideologically as a left-wing force for Basque national sovereignty, whose purpose is the achievement of an independent Euskal Herria based on social justice.

[citation needed] Victims' associations such as Covite have criticized the presence of their leaders at tributes to former members of the armed organization, and the militancy in ETA in the youth of its general coordinator Arnaldo Otegi, as well as some of the Sortu affiliates, has also been pointed out.

For his part, Otegi has reiterated on several occasions EH Bildu's commitment against ETA violence, rejecting public receptions of released prisoners, as well as his support for the victims, expressing his regret for the suffering caused.
