The use of social networks for protest purposes has been an essential element in recent global protests against the economic measures of privatization of public services. Social networks are changing political communication, mobilization and organization of collective protests. Taking into account the relationship between collective protests and new forms of network communication, the aim of this article is to analyze the new forms of citizenship empowerment from the collective protests in defense of public education in Spain. In the last five years the movement "Marea Verde" has generated protests on twitter that have generated new forms of empowerment of citizenship in the Spanish context. In this article we have analyzed three accounts of twitter with great activity and prominence, by the numbers of followers and tweets, of the social networks by "Marea Verde". In this article four categories of analysis have emerged that agglutinate and characterize the demands of collective protests through social networks. Two of the categories have been generated to reject the privatization of education and the standardized tests of the new educational reform act in the Spanish context. The other two categories claim for public education and an educational consensus between the political forces and the educational community.
