Riot controlRiot control measures are used by law enforcement, military, paramilitary or security forces to control, disperse, and arrest people who are involved in a riot, unlawful demonstration or unlawful protest. If a riot is spontaneous and irrational, actions which cause people to stop and think for a moment (e.g. loud noises or issuing instructions in a calm tone) can be enough to stop it. However, these methods usually fail when there is severe anger with a legitimate cause, or the riot was planned or organized.
RebellionRebellion, uprising, or insurrection is a refusal of obedience or order. It refers to the open resistance against the orders of an established authority. A rebellion originates from a sentiment of indignation and disapproval of a situation and then manifests itself by the refusal to submit or to obey the authority responsible for this situation. Rebellion can be individual or collective, peaceful (civil disobedience, civil resistance, and nonviolent resistance) or violent (terrorism, sabotage and guerrilla warfare).
Direct actionDirect action is a term for economic and political behavior in which participants use agency—for example economic or physical power—to achieve their goals. The aim of direct action is to either obstruct a certain practices (such as a government's laws or actions) or to solve perceived problems (such as social inequality). Direct action may include activities, often nonviolent but possibly violent, targeting people, groups, institutions, actions, or property that its participants deem offensive.
Crowd psychologyCrowd psychology (also mob psychology) is a branch of social psychology that deals with the ways in which the psychology of a crowd is different from the psychology of the individual persons who are the crowd. The field of crowd psychology enquires into the behaviors and thought processes of both the individual members of the crowd and the crowd as a collective social entity. The behavior of a crowd is much influenced by deindividuation, a person's loss of responsibility, and the person's impression of the universality of behavior, both of which conditions increase in magnitude with size of the crowd.
Black blocA black bloc is a tactic used by protesters who wear black clothing, ski masks, scarves, sunglasses, motorcycle helmets with padding or other face-concealing and face-protecting items. The clothing is used to conceal wearers' identities and hinder criminal prosecution by making it difficult to distinguish between participants. It is also used to protect their faces and eyes from pepper spray, which is used by police during protests or civil unrest. The tactic also allows the group to appear as one large unified mass.
ProtestA protest (also called a demonstration, remonstration or remonstrance) is a public expression of objection, disapproval or dissent towards an idea or action, typically a political one. Protests can be thought of as acts of cooperation in which numerous people cooperate by attending, and share the potential costs and risks of doing so. Protests can take many different forms, from individual statements to mass political demonstrations.
Political demonstrationA political demonstration is an action by a mass group or collection of groups of people in favor of a political or other cause or people partaking in a protest against a cause of concern; it often consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, in order to hear speakers. It is different from mass meeting. Actions such as blockades and sit-ins may also be referred to as demonstrations.
Great DepressionThe Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September 1929 and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%.
Political violencePolitical violence is violence which is perpetrated in order to achieve political goals. It can include violence which is used by a state against other states (war), violence which is used by a state against civilians and non-state actors (forced disappearance, psychological warfare, police brutality, targeted assassinations, torture, ethnic cleansing, or genocide), and violence which is used by violent non-state actors against states and civilians (kidnappings, targeted assassinations, terrorist attacks, torture, psychological and/or guerrilla warfare).
Class conflictIn political science, the term class conflict (also class struggle, class warfare, capital-labour conflict) identifies the political tension and economic antagonism that exist among the social classes of society, because of socioeconomic competition for resources among the social classes, between the rich and the poor. In the political and economic philosophies of Karl Marx and Mikhail Bakunin, class struggle is a central tenet and a practical means for effecting radical sociopolitical changes for the social majority, the working class.
