Communist Party of Nepal (Unity Centre), was a communist party in Nepal. CPN(UC) was formed on November 19–20, 1990, through the merger of Communist Party of Nepal (Mashal), Communist Party of Nepal (Fourth Convention), Proletarian Workers Organisation and Communist Party of Nepal (Janamukhi). Soon thereafter a group led by Dr. Baburam Bhattarai and Shital Kumar, that had left Communist Party of Nepal (Masal) joined the party.Samyukta Janamorcha Nepal was set up as the open mass front of the party.
The next year the party held its first convention. It adopted a line of "protracted armed struggle on the route to a new democratic revolution" and that the party would remain an underground party.
In 1992, in a situation of economic crisis and chaos, with spiralling prices as a result of implementation of changes in policy of the new Congress government, SJM and CPN(UC) stepped up their political agitation. A Joint People's Agitation Committee was set up together with the Communist Party of Nepal (Masal), the Nepal Communist League and the Communist Party of Nepal (Marxist-Leninist-Maoist). A general strike was called for April 6.
Violent incidents began to occur on the evening ahead of the strike. The Joint People's Agitation Committee had called for a 30-minute 'lights out' in the capital, and violent erupted outside Bir Hospital when activists tried to enforce the 'lights out'. At dawn on April 6, clashes between strike activists and police outside a police station in Pulchok (Patan) left two activists dead.
