Subarna Shamsher played a crucial role during the movement to attain democracy in Nepal and to remove the
Rana rule. He had initially founded the Nepalese Democratic Congress in March, 1948. Its main agenda was to destabilize the Rana regime and to introduce a multi-party democratic system in Nepal Its operations were run mainly from the
Indian state,
United Province which is present day
Bihar and
Uttar Pradesh. In 1950, both
Bishweshwar Prasad Koirala and Subarna Shamsher realized that the only way that the movement would succeed would be through the merger of their respective political parties. The only barrier to this was that, unlike the Nepalese Democratic Congress, the Nepalese National Congress headed by Koirala did not accept violence as a method to achieve democracy. After a string of talks and negotiations Subarna Shamsher made Koirala realize that violence will be needed and thus, the two parties came together to form the Nepali Congress. After the merger he spearheaded the movement and enabled it to arm and train a small army which then began destabilizing the Rana government in eastern parts of Nepal. The financing for all the activities of the Nepai Congress was done by Subarna Shamsher through his own personal funds. In late 1950, there was a general mobilization with violent protests and attacks taking place in
Birgunj and
Biratnagar. With situation getting worse for the Rana governor, the Royal Army eventually retreated from most of eastern Nepal which then came on the control of the Nepali Congress. This victory was short-lived as the new reinforced Rana forces overpowered the weaker forces of the Nepli Forces and drove them out of Nepal. But the struggle in Easter Nepal had the desired effect and all over Nepal people started rising against the Rana regime. By late 1951, the Rana Prime Minister
Mohan Shumsher Jang Bahadur Rana gave into the demands of the Nepali Congress and gave way for the reforms to be carried out by the Congress under the supervision of
King Tribhuvan. ==Interim government==
