Nicolae Ceaușescu's cult of personality
During the Cold War, Romanian dictator Nicolae Ceaușescu presided over the most pervasive cult of personality within the Eastern Bloc. Inspired by personality cults surrounding Kim Il Sung in North Korea, Mao Zedong in China and possibly King Carol II's, it started with the 1971 July Theses which reversed the liberalization of the 1960s, imposed a strict nationalist ideology, established Stalinist totalitarianism and a return to socialist realism.
