A social movement is a group of people who come together to promote a common cause, such as political change, social justice, or environmental protection.

The three main types of social movements are reform movements, which seek to change specific aspects of society, revolutionary movements, which seek to overthrow the existing social order, and countermovements, which seek to resist change.

Social movements can be caused by a variety of factors, including economic inequality, political oppression, social injustice, cultural change, technological change, environmental change, war, natural disasters, and pandemics.
