SJM was founded in 1991, with Dr. Baburam Bhattarai as its chairman. Except for the CPN, the Nepal Workers Peasants Organisation and the Nepal Marxist-Leninist Party 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 left it. The CPN cited that the Front has become a mere 'rubber stamp' of CPN.
1991 general election
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 stepped up their political agitation. A Joint People's Agitation Committee was set up together with the Communist Party of Nepal, the Nepal Communist League and the Communist Party of Nepal. 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 left two activists dead. Later in the day, a mass rally of the Agitation Committee at Tundikhel in the capital Kathmandu was attacked by police forces. As a result riots broke out, and the Nepal Telecommunications building was set on fire. Police opened fire at the crowd, killing several persons. The Human Rights Organisation of Nepal estimated that 14 people, including several on-lookers, had been killed in police firing. Ahead of the elections to local bodies the year SJM formed a front together with the Nepal Workers Peasants Party, Communist Party of Nepal, Communist Party of Nepal and Nepal Communist League. SJM obtained one deputy mayor, 8 municipal committee seats and around 5% of the seats in the Village Development Committees.
When CPN split in 1994, so did SJM on May 22. The hardline faction under the leadership of Prachandra and Dr. Baburam Bhattarai launched a parallel SJM. The mainstream group, led by Niranjan Govinda Vidya and Nirmal Lama was the one accorded the recognition by the Election Commission to the name SJM. On July 14 the Vidya/Lama-led SJM held its convention and decided to participate in upcoming elections.
