Contentious politics is the use of disruptive techniques to make a political point, or to change government policy. Examples of such techniques are actions that disturb the normal activities of society such as demonstrations, general strike action, direct action, riot, terrorism, civil disobedience, and even revolution or insurrection. Social movements often engage in contentious politics. The concept distinguishes these forms of contention from the everyday acts of resistance explored by James C. Scott, interstate warfare, and forms of contention employed entirely within institutional settings, such as elections or sports. Historical sociologist Charles Tilly defines contentious politics as "interactions in which actors make claims bearing on someone else's interest, in which governments appear either as targets, initiators of claims, or third parties."

Contentious politics has existed forever, but its form varies over time and space. For example, Tilly argues that the nature of contentious politics changed fairly dramatically with the birth of social movements in 18th-century Europe.
