Shortly after the split of several sectors of the Galician Nationalist Bloc (BNG) after its XIII National Assembly, the more important being Máis Galiza and Encontro Irmandiño (EI),[3] Several confluence processes began, with the "New Common Project" (NPC) being the most important one. However, the majority sector of Máis Galiza abandoned this process, seeking to create a more centrist political force and questioning the leadership of EI in the NPC.[4] Other parties and organizations also joined the NPC, including the Galician People's Front (FPG), Movemento pola Base (MPB), Galician Workers Front (FOGA) and Causa Galiza (this last organization left, criticizing the control exercised by EI in the project).[5]
Finally, in July 2012, the First National Assembly of the NPC was held in Santiago de Compostela, creating a new party with the name ANOVA-Irmandade Nacionalista, led by a "National Council" of 75 members. The assembly also decided the political bases of the new party, that include ecologism,[6]republicanism and Galician independence.[7] The organization included various historical figures of Galician nationalism like Xosé Manuel Beiras (ex-leader of the BNG), Martiño Noriega (then mayor of Teo, currently mayor of Santiago de Compostela), Mariano Abalo Costa (then leader of the FPG and ex-mayor of Cangas), Mario López Rico, Lidia Senra Rodríguez (ex-leader of the Sindicato Labrego Galego), David Fernández Calviño (the mayor of Manzaneda) or Luís Eyré Diéguez (ex-leader of the Socialist Collective).
In 2013 Unity of the Galician Left and New Socialist Left merged and created New Galician Left, as a new internal current within Anova. In 2014 a critical political organization within the party, called CERNA, was created. CERNA left the party after the results of the second National Assembly of Anova.[11][12] The same year, FOGA left Anova.[13]
Anova supported multiple left-wing unity lists all over Galiza in the municipal elections of 2015.[14] In some municipalities the party run alone, although with the legal coverage of the Son political party. This "instrumental" party was used by Anova and United Left to gain seats in the provincial deputations,[15] that are elected indirectly, based on the results of the local elections. The unity lists won in various municipalities, including the cities of A Coruña and Santiago de Compostela. In this last city Martiño Noriega, a member of Anova, was elected as the mayor. Other four members of Anova were elected mayors: Rafael Sisto Edreira in Teo, Benito Portela Fernández in Sada, Antonio Negreira Noya in Val do Dubra and David Rodríguez Estévez in Manzaneda.
