Left-wing extremism refers to political movements that advocate for radical changes in society, often through revolutionary means. These groups typically seek to address issues like economic inequality, social justice, and anti-capitalism. They may employ tactics such as protests, direct action, or even violence to achieve their goals, believing that traditional political processes are insufficient. Historically, left-wing extremism has been associated with various organizations, such as the Weather Underground in the United States and the Red Army Faction in Germany. While these groups share a common ideology, their methods and specific objectives can vary widely, reflecting diverse interpretations of leftist principles.
