Opposition to authoritarianism refers to the resistance against political systems where power is concentrated in a single authority or a small group, often limiting individual freedoms and rights. This opposition can manifest through various means, including protests, political activism, and the promotion of democratic values. Historical examples include movements against regimes like Nazi Germany and Soviet Union. Activists and organizations often advocate for transparency, accountability, and the protection of civil liberties. Notable figures in this struggle include Nelson Mandela, who fought against apartheid in South Africa, and Aung San Suu Kyi, who campaigned for democracy in Myanmar.
