Isidoro Balaguer Sanchis, better known as Doro Balaguer (Valencia, 1931-ibídem, January 29, 2017). Spanish painter and politician, member of the Parpalló Group and leader of the Communist Partit of the Country Valencià first, and founder of Unitat del Poble Valencià after.3

Coming from a family of industrialists and merchants, Doro Balaguer studied Fine Arts in Valencia and lived in Paris, where he was influenced by the most avant-garde trends in painting of the 1950s. He became politically involved in the Communist Party of Spain (PCE) ). When he returned to Valencia, he was part of the Parpalló group, founded in 1956. Shortly after, he abandoned painting and devoted himself to politics.

During the Franco regime he became one of the leaders of the PCE in hiding in the Comunitat Valenciana. With the arrival of the democratic Transition and the grouping of the communist formations territorially in Valencia in a single formation, the Communist Partit of the Valencià Country, Balaguer would be one of its leaders until the 1980s, when together with a Valencian sector, left the formation to found the Agrupament d'Esquerra del País Valencià, a short-lived party that in the general elections of 1982 participated in the Unitat del Poble Valencià (UPV) coalition, which in turn would become a political party two years later.

In addition, Doro Balaguer was candidate for the presidency of the Valencian Regional Government by UPV in the elections to the Valencian Cortes of 1983, where he obtained little more than 3% of votes and, although he remained as the fourth political force, he did not win seats.
