A cult of personality, or cult of the leader, arises when a country's regime – or, more rarely, an individual – uses the techniques of mass media, propaganda, the big lie, spectacle, the arts, patriotism, and government-organized demonstrations and rallies to create an idealized, heroic, and worshipful image of a leader, often through unquestioning flattery and praise. A cult of personality is similar to apotheosis, except that it is established by modern social engineering techniques, usually by the state or the party in one-party states and dominant-party states. It is often seen in totalitarian or authoritarian countries. The term came to prominence in 1956, in Nikita Khrushchev's secret speech On the Cult of Personality and Its Consequences, given on the final day of the 20th Congress of the Communist Party of the Soviet Union. In the speech, Khrushchev, who was the First Secretary of the Communist Party – in effect, the leader of the country – criticized the lionization and idealization of Joseph Stalin, and by implication, his Communist contemporary Mao Zedong, as being contrary to Marxist doctrine. The speech was later made public and was part of the "de-Stalinization" process in the Soviet Union.
