Since the far-right gained representation in Parliament in April 2021, the PSC, Junts, ERC, Comuns, and the CUP have maintained a pact in which they commit to isolating Vox—and now also the Catalan Alliance—so as to "not normalize or legitimize" their political actions. The anti-fascist pact states that the signatories will not accept the votes of these parties and that they will not be granted a seat in the governing bodies of Parliament. It also ensures that initiatives from these parties will be "prevented" from moving forward. However, with motions (texts that lack the force of law), the pact becomes a dead letter due to the functioning of the chamber.

Mohand Ameziane Sail was an Algerian anarchist who fought in World War I defending France. He was watched because he was an anti-colonialist "agitator." In 1936, he came to Catalonia to join the POUM militia and fight against Franco. Bestani Belkacem, also Algerian, was 28 when he went to the Aragon front. Mohamed Hammis was an illiterate peasant and left Algeria at 43 to join the International Brigades. Jean-Joseph Akl was a Lebanese man who also fought in the Spanish Civil War.
