A decade ago, in response to the harsh exit from the economic crisis resulting from the financial collapse of Lehman Brothers due to blind deregulation and the subsequent sovereign debt crisis, popular indignation took hold with a citizen protest that took to the streets. The movement of the indignados became an anti-establishment clamour that was joined by sectors of the middle classes: with the social cuts in the public sector, the malaise had reached far beyond ideologically aware circles. Social justice, non-violent disobedience, anti-capitalism and the demand for a more participatory democracy were the axes of a protest that overflowed the institutions, the political parties - including those of the classical left - and the trade unions. Together with old fighters of the alter-globalization of the 1990s and the "No to war" - the Iraq War of 2003 - many young people without a future signed up to a possibility of rupture with the vocation of transforming mentalities and organising change. Social networks gave wings to a new kind of citizen mobilization that wanted to channel the discomfort and struggles that had been fragmented until then: for housing, against corruption, against cuts in various sectors, against war, against climate change, for feminism... From the bottom to the top, turning squares -the Catalunya square in Barcelona; the Puerta del Sol square in Madrid- into assembly camps, for a few months the mirage of the birth of a new political, social and ideological time was produced.
