On the 15th May 2011, one week before the spanish local and regional elections, the movement “¡Democracia Real YA!” convoked demonstrations in over 60 cities throughout Spain. About 150.000 “indignados” took the streets, against to what they called “antisocial means in the hands of bankers”, referring to the adjustments that Spain did in 2010 in order to restrain the European financial crisis, which included rescuing measures for the banks (which the society blames as responsible for the crisis), whilst social cuts were being announced.
That same night, spontaneous protest camps took place in several cities of Spain, highlighting the protest camp at the Puerta del Sol of Madrid and the one at Plaça Catalunya of Barcelona.
The first assembly in Plaça Catalunya, on 16th May, was attended by about 150 people. Campers in Barcelona, as in other cities of Spain, decided to remain indefinitely at the square and they began to organise by creating work groups: communication, logistics, art, infrastructure, cuisine, activities, audiovisual, economics, law etc..
Attendance at the assemblies in Plaça Catalunya was growing constantly and on 20th May, besides the decision of the Electoral Board to ban any kind of protest because of the elections, more than 15.000 people attended the assembly and about 3.000 people slept that night at the square.
On the Internet, the protests became popular as #SpanishRevolution, referring to the hashtags of Twitter, which was the primary means of organization of the “indignados”.
