The 15 October 2011 global protests were part of a series of protests inspired by the Arab Spring, the Icelandic protests, the Portuguese "Geração à Rasca", the Spanish "Indignants", the Greek protests, and the Occupy movement. The protests were launched under the slogan "United for #GlobalChange", to which the slogan "United for Global Democracy" was added by many people's assemblies. The protest was first called for by the Spanish Plataforma ¡Democracia Real YA! in May 2011 and endorsed by people's assemblies across the world. Reasons were varied but mainly targeted growing economic inequality, corporate influence over government and international institutions, and the lack of truly democratic institutions allowing direct public participation at all levels, local to global. Global demonstrations were held on 15 October in more than 950 cities in 82 countries. The date was chosen to coincide with the 5-month anniversary of the first protest in Spain. General assemblies, the social network n-1, mailing lists, Mumble voice chat, open pads such as Pirate Pad and Titan Pad, and Facebook were used to coordinate the events. Some protests were only a few hundred in number, whereas others numbered in the hundreds of thousands, with the largest in Madrid numbering half a million and the second largest city Barcelona with 400,000.
