Political radicalism refers to the advocacy for fundamental changes in political, social, or economic systems. Radicals often seek to address perceived injustices and inequalities, believing that existing structures are inadequate for achieving true progress. This can involve a wide range of ideologies, from leftist movements advocating for social justice to right-wing groups promoting nationalism. Radicalism can manifest in various forms, including protests, grassroots organizing, and even revolutionary actions. Historical examples include the French Revolution and the Civil Rights Movement in the United States. While some view radicalism as necessary for change, others see it as a threat to stability and order.
