Much of the pre-history of the platform is around local civic activism and movement of Right to the city as "Pravo na grad". The political turn was made significant with escalation of protests and smaller green parties joining forces with activists. In April 2017, the Platform formed a coalition with four left and green parties in Zagreb, creating for the first time an alliance of progressive political organizations in Zagreb.[4] In their very first municipal elections held in Zagreb in May 2017, the coalition won 7,6 % of votes (4 seats) in Zagreb City Assembly, 21 seats in city districts and also 41 seats in local councils, with many of the elected representatives being young persons who have previously not been engaged in institutional politics."[5]
The platform describes itself as very diverse, "formed in February 2017 by citizens from all walks of life (activists, cultural workers, trade unionists, social entrepreneurs etc., many of whom have been previously active for years in social movements in Zagreb)[5] and different from existing parties in aiming to build a "new politics based on the principles of wide participation, inclusiveness and openness".[7]
