After the political change of 2046, Nepal Sadbhavna Party is a political party that emerged representing Madhesh. The 'legacy' of most of the Madhesh-centric parties that exist now is connected with this goodwill. Gajendra Narayan Singh was the founder president.

In the year 2050, Sadbhavana made various demands to the government. After those demands were not met, the hunger strike started. It seems that the Madhesh-centric parties are still keeping the three demands that Sadbhavana made 32 years ago. The demands are the same, the only difference is that there are many parties and they keep getting caught in the interests of power .

After the death of Gajendra Narayan, the Sadbhavana Party was disintegrated . Now the goodwill does not even exist . But some of the Madhesh agendas raised by Singh's leadership at that time are still being carried by the Madhesh-centric new party. At that time, Sadbhavana demanded the group recruitment of 'Madheshi' in the Royal Nepali Army, distribution of citizenship certificates, reservation in employment, restructuring of constituencies, constitutional status of Hindi as the national language, establishment of federal government, solution of squatter problems.

Sadbhavana started a hunger strike after their demands were not met. And issues such as the increase in corruption, cheating by the Selection Commission in the recruitment of teachers across the country were also raised. At that time, the main agenda of the party was centered on the easy distribution of citizenship. Because about 1.5 million Madhesh minors did not get citizenship, the agenda was raised . Before the hunger strike, Sadbhavana had announced a program of campaigning in the district/district from 1st to 12th November 2050 and organizing a public meeting from 13th to 17th.

Gajendra Narayan Singh was also criticized after his speech in Hindi in the Parliament after 2046 . Old leaders still remember the incident where Gajendra Narayan, who used to wear kurta and dhoti, removed the record of his speech in Parliament.

In order to fulfill the demands put forward by them, in addition to the Goodwill hunger strike, they also organized a joint meeting to gather the moral support of the then major opposition parties, including the UML. But only the representatives of United Janamorcha Nepal and Nepal Labor Kisan Party participated in the meeting. Due to which, doubts arose about the support of the opposition parties .
