Ideologically, the party was close to the Nepali Congress, while a majority of its leaders have been part of Congress at different points in time, especially before the 2006 Madhesh Movement.

Thakur himself was treasurer and head of party disciplinary department before he left the Nepali Congress party. They were elected several times to the House of Representatives on the party ticket.
The President of Nepal issued the second ordinance to amend the Political Parties Act on 18 August 2021. This opened the way to formalize the splits inside the dispute between two factions of Janata Samajbadi Party, Nepal. The faction of party led by Mahantha Thakur, which had a long dispute with party chairman Upendra Yadav registered their party with the Election Commission. At the time of the launch, the party claimed to have 13 members in the two national houses of parliament.
The new party was supported by 16 MLAs in Madhesh Provincial Assembly. A Central Committee with 24 members was announced as well. Senior leader of the Loktantrik Samajbadi Party Rajendra Mahato quit the party and announced a Rastriya Mukti Party.
The party emerged as fourth largest party of Madhesh province winning 16 local levels from among 753 local levels even standing alone in the elections. Nepali Congress emerged as single largest party of Madhesh province for second consecutive term, CPN (UML) emerged as second and while Janta Samajbadi was limited to third position.
In the mid of March, the party started talks with the Nepali Congress for a possible long term alliance between the two parties. Party chairman revealed this in a party meet in Janakpur on 22 March 2022. The party formed a committee for bilateral talks with Nepali Congress consisting Sharbendra Nath Shukla and Laxman Lal Karna in which party senior leader Sharat Singh Bhandari played vital role as mediator.
Bhandari had stood long for a Loktantrik alliance between democratic parties of Nepal. Both Loktantrik Samajwadi Party and Nepali Congress have some common ideologies including social democracy, democratic socialism. The party won 9 seats in Madhesh province while it won 3 seats in Lumbini province. However, in the general election it was limited to 4 seats only after being unable to cross 3% threshold due to wave of newly formed parties.
