It was formed in 1998 as a schism from Initiative for Catalonia Greens (ICV). It comprises an alliance of Party of the Communists of Catalonia, Living Unified Socialist Party of Catalonia, POR, PRT-IR, PASOC, CEA, and CLI. After competing in a series of elections with their former colleagues at Iniciativa, the two parties agreed to run together as an electoral coalition. In 2015, the party joined the electoral coalition En Comú Podem. In 2017, it was one of the founding parties of Catalunya en Comú, being expelled from the organization two years later as it was no longer the Catalan correspondent of United Left.
