Man Mohan, an erstwhile leader of the radical faction of the Communist Party of Nepal, had taken part in organising the 'Central Nucleus' (an attempt to rebuild the CPN). Since the breakup of the Central Nucleus in 1973, he had led his own group of followers but it was not until 1979 that they constituted themselves as a separate party. Until 1982 the party was known as Communist Party of Nepal (Unity Conference).Rawal, Bhim Bahadur. Nepalma samyabadi andolan: udbhab ra vikas. Kathmandu: Pairavi Prakashan. Chart nr. 1.
