Soviet dissidents were persons who disagreed with certain features in the embodiment of Soviet ideology and who were willing to speak out against them. The term dissident was used in the Soviet Union in the period following Joseph Stalin's death until the fall of communism. It was used to refer to small groups of marginalized intellectuals whose modest challenges to the Soviet regime met protection and encouragement from correspondents. Following the etymology of the term, a dissident is considered to "sit apart" from the regime. As dissenters began self-identifying as dissidents, the term came to refer to an individual whose non-conformism was perceived to be for the good of a society.
Political opposition in the USSR was barely visible and, with rare exceptions, of little consequence. Instead, an important element of dissident activity in the Soviet Union was informing society (both inside the Soviet Union and in foreign countries) about violation of laws and human rights. Over time, the dissident movement created vivid awareness of Soviet Communist abuses.
Soviet dissidents who criticized the state faced possible legal sanctions under the Soviet Criminal Code and faced the choice of exile, the mental hospital, or the labor camp.Anti-Soviet political behavior, in particular, being outspoken in opposition to the authorities, demonstrating for reform, writing books were defined in some persons as being simultaneously a criminal act (e.g., violation of Articles 70 or 190-1), a symptom (e.g., "delusion of reformism"), and a diagnosis (e.g., "sluggish schizophrenia").
In the 1950s, Soviet dissidents started leaking criticism to the West by sending documents and statements to foreign diplomatic missions in Moscow. In the 1960s, Soviet dissidents frequently declared that the rights the government of the Soviet Union denied them were universal rights, possessed by everyone regardless of race, religion and nationality. In August 1969, for instance, the Initiating Group for Defense of Civil Rights in the USSR appealed to the United Nations Committee on Human Rights to defend the human rights being trampled on by Soviet authorities in a number of trials.
