This document summarizes the emergence and evolution of citizen movements in Spain following the 2011 15M protests. It describes how occupations of public squares spread decentralized activism and use of digital tools. Some movements organized locally and engaged institutions, while others formed political parties like Podemos. Municipal-level citizen platforms then collaborated to take power in cities, such as Ahora Madrid. These "confluences" developed shared programs and campaigned using social networks and independent community organizing. The document traces this evolution from 15M to direct digital democracy initiatives in Madrid today.
