ABSTRACT
The 'vertical' and 'horizontal' political logics diverge particularly in their approach to the representative structures and in their definitions of the most appropriate forms of political participation. The transversal, changing and plural nature of 15M makes it difficult to provide categorical explanations of the movement and its component parts. This chapter analyses the following: call-outs and demonstrations without the traditional intermediary structures; acampadas and assemblies; the formulation and dissemination of ideas, as well as coordination and modification of media and political agendas, through digital tools; citizen monitoring processes and platforms; stopping evictions; popular legislative initiatives and escraches; citizen mareas against social spending cuts; sieges of representative institutions; blockades and occupations of institutions and megaprojects; and the emergence of new political parties. The electoral system has its own limitations that affect access to power through the representative structures, particularly for smaller and non-mainstream parties.
