The United People's Front of Nepal, (Nepali: संयुक्त जनमोर्चा नेपाल Sanyukta Janamorcha Nepal or SJM) was the mass front of the Communist Party of Nepal (Unity Centre).
SJM was founded in 1991, with Dr. Baburam Bhattarai as its chairman. Except for the CPN(UC), the Nepal Workers Peasants Organisation and the Nepal Marxist-Leninist Party (later CPN(MLM)) took part in the formation. Both factions did however leave the Front rather soon, the NWPO left just before the 1991. After the SJM was restructured on August 17, 1991, the CPN(MLM) left it. The CPN(MLM) cited that the Front has become a mere 'rubber stamp' of CPN(UC).
In the elections in the country held in 1991, SJM won nine seats and became the third largest force in the parliament.
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.
