In 2011 numerous 'Occupy' and anti-austerity protests took place across Europe and the United States. Passionate indignation at the failure of political elites became a mobilizing force against formal political institutions. In Greece a mass movement known as the Aganaktismeni (the Indignant) became the main agent of social resistance to the memorandum signed by the Greek government, the European Union and the International Monetary Fund. The Greek movement did not take the form of a social movement sharing a collective identity. Left-wing protestors played a prominent role. Protestors embracing right-wing populist frames also participated actively in collective mobilizations, while segments of the extreme right attempted to manipulate rage to their advantage. During the Greek Indignant movement civil society remained a terrain contested by conflicting political forces. This unique feature of the Greek movement posed a completely different challenge to the principles of diversity and inclusiveness than the one debated within the Spanish Indignados and the Occupy protests. Furthermore, it illustrates that rage and indignation may spark dissimilar forms of political contention. Hence, rage and indignation do not merely motivate ‘passive citizens’ to participate in collective protest. They are linked to cognitive frames and individual preferences, which influence protestors’ claims and mobilizations’ political outcomes. Accordingly, advances in democratization and inclusive citizenship are only one of the possible outcomes of mobilizations prompted by rage and indignation.
