What is Demonstration: Definition and 123 Discussions

A 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, to hear speakers. It is different from mass meeting.
Actions such as blockades and sit-ins may also be referred to as demonstrations. Demonstrations can be nonviolent or violent (usually referred to by participants as "militant"), or can begin as nonviolent and turn violent depending on the circumstances. Sometimes riot police or other forms of law enforcement become involved. In some cases this may be in order to try to prevent the protest from taking place at all. In other cases, it may be to prevent clashes between rival groups, or to prevent a demonstration from spreading and turning into a riot.
The term has been in use since the mid-19th century, as was the term "monster meeting", which was coined initially with reference to the huge assemblies of protesters inspired by Daniel O'Connell (1775–1847) in Ireland. Demonstrations are a form of activism, usually taking the form of a public gathering of people in a rally or walking in a march. Thus, the opinion is demonstrated to be significant by gathering in a crowd associated with that opinion.
Demonstrations can promote a viewpoint (either positive or negative) regarding a public issue, especially relating to a perceived grievance or social injustice. A demonstration is usually considered more successful if more people participate. Research shows that anti-government demonstrations occur more frequently in affluent countries than in poor ones.
Historian Eric Hobsbawm wrote of demonstrations: Next to sex, the activity combining bodily experience and intense emotion to the highest degree is the participation in a mass demonstration at a time of great public exaltation. Unlike sex, which is essentially individual, it is by its nature collective… like sex it implies some physical action—marching, chanting slogans, singing—through which the merger of the individual in the mass, which is the essence of the collective experience, finds expression.
