Jordi Arquer

[1] During the dictatorship of Miguel Primo de Rivera, he participated in the clandestine opposition, collaborating with the independentista groups of Francesc Macià.

Once the Second Spanish Republic was proclaimed, Arquer was one of the founders of a Communist "Right Opposition" party, Bloc Obrer i Camperol (BOC), and an advocate of the Working Alliance (Aliança Obrera).

In 1931 he published Los comunistas ante el problema de las nacionalidades ibéricas, and after reviewing the history of Catalonia and the Catalan movement, was favorable to the recognition of self-determination of Catalonia and indicated the convenience of a Union of Iberian Socialist Republics.

During the Spanish Civil War (1936–1939), he was one of the organizers and heads of the POUM militia, which operated on the Aragon front.

[4] He continued to advocate for this organisation in publications and magazines such as Endavant, L'Insurgent, Quaderns de l'exili, La Nostra Revista (Mexico), Ressorgiment (Argentina), Germanor (Chile) and others, circulated in countries including the United States.
