A social movement is a loosely organized effort by a large group of people to achieve a particular goal, typically a social or political one.[1][2] This may be to carry out, resist or undo a social change. It is a type of group action and may involve individuals, organizations or both. Definitions of the term are slightly varied.[3] Social movements have been described as "organizational structures and strategies that may empower oppressed populations to mount effective challenges and resist the more powerful and advantaged elites".[4] They represent a method of social change from the bottom within nations
