Un País en Comú, whose final name will be decided by membership referendum, is the third Catalan progressive unity project with en comú (“together” or “in common”) in its title. The first, in June 2014, was the broad activist coalition that under the name of Barcelona En Comú won the May 2015 Barcelona city council election. In defeating the ruling conservative nationalist Convergence and Union (CiU) the new formation made former housing rights activist Ada Colau the city’s mayoress and a reference point for radical politics across the Spanish state.
