A resistance movement is an organized group of people that tries to resist the government or an occupying power, causing disruption and unrest in civil order and stability. Such a movement may seek to achieve its goals through either the use of violent or nonviolent resistance, or the use of force, whether armed or unarmed. In many cases, as for example in the United States during the American Revolution, or in Norway in the Second World War, a resistance movement may employ both violent and non-violent methods, usually operating under different organizations and acting in different phases or geographical areas within a country.

Civil resistance is a form of political action that relies on the use of nonviolent resistance by ordinary people to challenge a particular power, force, policy or regime. Civil resistance operates through appeals to the adversary, pressure and coercion: it can involve systematic attempts to undermine or expose the adversary's sources of power. Forms of action have included demonstrations, vigils and petitions; strikes, go-slows, boycotts and emigration movements; and sit-ins, occupations, constructive program, and the creation of parallel institutions of government.
