Abstract

Ideology can be understood as a type of cultural system, a set of interrelated meanings that are symbolically mediated through semiotic devices such as metaphors. Ideologies underlie social orders as well as help people make sense of their environment and decide on courses of action. While much has been said about ideology, little has been written on the sources of ideological change beyond pointing to ideological entrepreneurship. Even less has been written on the relationship between violent and disruptive social movements and ideology beyond pointing to the ideological motivations for the movements. We contend that extreme protests are often triggered by an ideological crisis, that is, an intolerable disconnection between the ideology adopted by some group and the current circumstances or, alternatively, an inability of their ideology to make sense of their current situation. Moreover, extreme protests are a form of ideological work, as they are often sources of ideological inspiration, development, and change.
