Radicalization in the context of "Anarchism in Spain"

Violent extremism is a form of extremism that condones and enacts violence with ideological or deliberate intent, such as religious or political violence. Violent extremist views often conflate with religious and political violence, and can manifest in connection with a range of issues, including politics, religion, and gender relations.

Although "radicalization" is considered by some to be a contentious term, its general use has come to regard the process by which an individual or group adopts violence as a desirable and legitimate means of action. According to the RAND Corporation, extremism is a term used to characterize a variety of attitudes, beliefs, and behaviors that often are on the extreme end of the political, religious, or ideological spectrum within civil society.
