The first steps for constituting the political space previously represented by the Catalunya Sí que es Pot and En Comú Podem alliances into a permanent political party can be traced to January 2016, when the party's trademark was provisionally registered in the interior ministry and Mayor of BarcelonaAda Colau announced her intention of establishing her own, autonomous party separate from Podemos.[3][6][7] On 19 December 2016, the "Un País en Comú" (English: "A Country in Common") platform was launched with the aim of constituting the political space previously represented by the Catalunya Sí que es Pot and En Comú Podem alliances into a permanent political party.[8]
The platform's establishment had been supported by Initiative for Catalonia Greens (ICV), United and Alternative Left (EUiA), Barcelona en Comú and Equo,[9] with it holding its first public event on 29 January 2017 in Barcelona,[10][11] and the party's founding congress on 8 April.[12] Organizational disagreements in March over the voting system selected to elect the leadership team and the ideological principles that should govern the new platform had seen regional Podemos/Podem leader, Albano Dante Fachin, opting out of the founding congress at the last moment, promising future collaboration with the other constituent parties but rejecting to integrate Podem into the new party.[13][14][15] Despite this, several Podem members disaffected with Fachin's leadership, such as Jéssica Albiach o Marc Bertomeu, did join the new party on their own accord.[16][17][18]
The definitive name of the party was to be chosen in a voting among party members following the founding assembly, with several proposals being registered in advance to prevent a similar case as what happened to the "Guanyem" trademark in 2014: Catalunya en Comú (Catalan for "Catalonia in Common"), En Comú Podem ("In Common We Can"), En Comú ("In Common") or Comuns ("Commons").[19][20] In a final voting held on 22 May 2017, name "Catalunya en Comú" was picked by party members over "En Comú Podem" in a 54–46% vote.[21][22]
