The Occupy movement was an international populist socio-political movement that expressed opposition to social and economic inequality and to the perceived lack of real democracy around the world. It aimed primarily to advance social and economic justice and different forms of democracy. The movement has had many different scopes, since local groups often had different focuses, but its prime concerns included how large corporations control the world in a way that disproportionately benefits a minority, undermines democracy and causes instability.

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. This may be to carry out a social change, or to resist or undo one. It is a type of group action and may involve individuals, organizations, or both. 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". They represent a method of social change from the bottom within nations. On the other hand, some social movements do not aim to make society more egalitarian, but to maintain or amplify existing power relationships. For example, scholars have described fascism as a social movement.
