A resistance movement is an organized effort by some portion of the civil population of a country to withstand the legally established government or an occupying power and to disrupt civil order and stability. It may seek to achieve its objectives through either the use of nonviolent resistance (sometimes called civil 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.
