Opposition movements are groups or organizations that challenge the policies, actions, or authority of a government or ruling body. These movements often arise in response to perceived injustices, such as human rights violations, corruption, or lack of political freedom. They can take various forms, including protests, strikes, and political campaigns, and may seek to bring about social or political change. These movements can be peaceful or violent, depending on the context and the government's response. Notable examples include the Civil Rights Movement in the United States and the Arab Spring in several Middle Eastern countries. Opposition movements play a crucial role in shaping political landscapes and advocating for the rights of citizens.
