From social mobilisation to institutional politics: Reflecting on the impact of municipalism in Madrid and Barcelona

In the 2015 local elections, political formations with their roots in social movements took control of several Spanish city councils, including Madrid and Barcelona. The wave of protests that began with the 15-M movement in 2011 gave way to an electoral model that aspired to promote transformative politics and new ways of ‘doing politics’. The aim of the present study is to examine the scope and the limits of this move into the institutions in Madrid and Barcelona (2015–2019). The case studies involved in-depth interviews and a documentary review. Results reveal significant differences between the two cities.
