Extremist movements are groups or organizations that advocate for radical changes in society, often through the use of violence or coercion. These movements can be based on political, religious, or ideological beliefs and typically reject mainstream values. They may seek to impose their views on others, leading to conflict and social division. Such movements can emerge in various contexts, including political revolutions, religious fundamentalism, or nationalist movements. They often attract individuals who feel marginalized or disenfranchised, providing a sense of identity and purpose. Understanding these movements is crucial for addressing the underlying issues that fuel their growth.
