– a typology employed by political scientists to describe modern regimes in which the state regulates nearly every aspect of public and private behavior. Totalitarian regimes mobilize entire populations in support of the state and a political ideology, and do not tolerate activities by individuals or groups such as labor unions, churches and political parties that are not directed toward the state's goals. They maintain themselves in power by means of secret police, propaganda disseminated through the state-controlled mass media, regulation and restriction of free discussion and criticism, and widespread use of terror tactics.
