The present study is devoted to the analysis of the protest culture of Spain in the 21st century on the example of the activity of the political party «Podemos». We will try to understand how the left-wing radical party, founded in 2014, has gained popularity and serious political influence in a country with pronounced multicultural diversity in such a short time. The aim of the study is to analyze the protest culture in Spain, using the example of the activity of the «Podemos» party, which has a serious impact on the political situation both in the country and in the region. To achieve this goal, the following tasks are set: to analyze the historical and national cultural background of the emergence of the protest movement in Spain; to determine its goals and features; to reveal the reasons for the manifestation of radical sentiments in European political discourse in connection with the advancement of electronic communication channels. The relevance of the research is to study contemporary radical trends in on-line space for developing further strategies to counter mass radical and separatist movements capable of destabilizing the situation and leading to a possible cultural and political collapse in the world. A thorough analysis of modern electronic communication channels is required, since it has made the protest movement culture even more dynamic, giving new opportunities for propagation. Of particular concern is the fact that the activists of radical movements, including the «Podmos» party members, are the intellectual elites of countries that are able to manipulate and influence the mood of the masses. In general, there is discontent, apathy, anti-eliteism in European society, as evidenced by the nationalism that is flaring up in Europe, together with ethnocentrism, anti-Semitism, fascism, and francism, whose instruments of influence have changed due to the appearance of the Internet. Increasingly, representatives of the establishment voice the need for a complete transformation of political, socio-economic, institutional systems that, in the opinion of many, have lost their effectiveness and sustainability. Populists play on this wave of discontent, not taking into account modern realities, but skillfully manipulating the mood of the masses especially in the Internet space, - so a new digital protest culture is emerging and gaining momentum. Based on the analysis in the study, we came to the conclusion that the protest culture in Spain has its own history based on the national image of the Spaniard (hidalgo) world, formed at the junction of European and Mauritanian cultures, brought up on the values and traditions of Catholicism and Islam. Protest is part of the Spaniard’s worldview. It manifests itself in its aesthetics, creativity, rejection of the established social canons. In general, protest moods are growing in the world, including prosperous European countries experiencing a boom in social media, as evidenced by support of a solid part of the population in Spain left-wing radical party «Podemos».
