To put an end to bipartisanship and the power of banks and business corporations, to put an end to the cuts or to make the constitutional promise of decent housing come true. 15-M managed to place these issues and many others at the centre of public debate and transformed them into demands in the manifestos in Barcelona and Madrid. The movements and parties that emerged from that social outburst (or those that felt challenged) took them up and have defended them ever since, but most of the milestones are still in their infancy and, a decade later, are still valid.

"When everything explodes, you see that it could go further, it seemed as if you were making the revolution". The feeling for many was precisely this, the one described in a few words by Miquel Àngel Sànchez, who together with hundreds of people decided to camp in Barcelona's Plaça Catalunya ten years ago, tired of suffering the cuts associated with an economic crisis that 15-M wanted to translate into democracy. Probably few imagined that the demonstration on that Sunday, May 15, 2011, framed in a wave of unrest generated in the networks, would unleash a social movement that would shake the Catalan and Spanish political and social system. Because the spirit of 15-M was this: to organise anger. Ten years later, however, the material achievements are meagre and the most tangible success is a cultural change for thousands of people.

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.
