Riots often occur in reaction to a perceived grievance or out of dissent.
Historically, riots have occurred due to poor working or living conditions, government, oppression, taxation or conscription, conflicts between Ethnic groups, food supply or religions, the outcome of a sporting event or frustration with legal channels through which to air grievances.
Riots typically involve vandalism and the destruction of private and public property.
The specific property to be targeted varies depending on the cause of the riot and the inclinations of those involved.
Targets can include shops, cars, restaurants, state-owned institutions, and religious buildings.
A protest expresses a strong reaction of events or situations.
The term protest usually now implies a reaction against something, while previously it could also mean a reaction for something.
Protesters may organize a protest as a way of publicly and forcefully making their opinions heard in an attempt to influence public opinion or government policy, or may undertake direct action in an attempt to directly enact desired changes themselves.
Self-expression can, in theory, in practice or in appearance, be restricted by governmental policy, economic circumstances, religious orthodoxy, social structures, or media monopoly.
When such restrictions occur, opposition may spill over into other areas such as culture, the streets or emigration.
A protest can itself sometimes be the subject of a counter-protest.
In such a case, counter-protesters demonstrate their support for the person, policy, action, etc. that is the subject of the original protest.
Civil disorder, also known as civil unrest or civil strife, is a broad term that is typically used by law enforcement to describe one or more forms of disturbance caused by a group of people.
Civil disturbance is typically a symptom of, and a form of protest against, major socio-political problems; the severity of the action coincides with public expression(s) of displeasure.
Examples of civil disorder include, but are not necessarily limited to: illegal parades; sit-ins and other forms of obstructions; riots; sabotage; and other forms of crime.
It is intended to be a demonstration to the public and the government, but can escalate into general chaos
