High Quality Content by WIKIPEDIA articles! A resistance movement is a group or collection of individual groups, dedicated to fighting an invader in an occupied country or the government of a sovereign nation through either the use of physical force, or nonviolence. The term resistance is generally used to designate movement considered legitimate. Organizations and individuals critical of foreign intervention and supporting forms of organized movement tend to favor the term. When such a resistance movement uses violence, those favorably disposed to it may also speak of freedom fighters.
