Rastriya Prajatantra Party was established on 15th Jestha, 2047 B.S. with an objective of providing an alternative democratic force to the nation. Nationalism, democracy and liberalism have remained as the three main ideological pillars of the party. Similarly, sovereignty of the people, competitive multi-party democracy, constitutional monarchy and the principle of rule of law are the political belief of the party. Despite having common agreement on major political issues, unfortunately, due to some technical differences two separate organizations with identical name, ideology and statute came into existence on the same day. Two RPPs contested the general election of 2048 B.S. separately. Obviously the results were not encouraging. Following the serious debacle in the election, under the pressure of party workers two RPPs decided to merge.
RPP held its first general convention in 2050 B.S. in Kathmandu, and unanimously elected former prime-minister Surya Bahadur Thapa as chairman. Former prime-minister Lokendra Bahadur Chand and Rajeshore Devkota were elected respectively as leader and co-chairman of the party. As provided in the party statute Padma Sundar Lawati was nominated as vice-chairman and Rabindra Nath Sharma, Pashupati Shamsher Rana and Prakash Chandra Lohani were nominated as general secretaries. Kamal Thapa became spokesman.
In the second general election held in 2051 B.S. united RPP secured eighteen percent of the total votes polled. Thus RPP became the third largest party in the parliament. Since none of the parties got absolute majority it was a hung parliament. The political developments that took place during the tenure of the second parliament gave opportunities for two RPP leaders namely Surya Bahadur Thapa and Lokendra Bahadur Chand to become the prime-minister of the country successively in the coalition governments. However, during this period the party saw serious differences among the top leadership, which eventually led once again for formal split of the party.
The second general convention of the party took place in 2054 B.S. in Birgunj. The Birgunj convention elected Surya Bahadur Thapa once again as chairman. Prakash Chandra Lohani, Pashupati Shamsher Rana and Kamal Thapa were nominated as vice-chairman, general secretary and spokesman respectively. Since two RPPs once again fought the general election with separate identity, the performance naturally were not good. However, it succeeded in retaining its third position in the parliament. Following the general election two factions again merged.
The third general convention held in Pokhara in 2059 B.S. elected Pashupati Samshere Rana as chairman. According to the party statute Padam Sunder Lawoti, Kamal Thapa and Roshan Karki were nominated as vice-chairman, general secretary and spokes-person.
The first ever special general convention of the party took place in 2062 B.S. in Kathmandu. The special general convention passed a vote of no confidence motion against Pashupati Shamsher Rana and elected Kamal Thapa as chairman of the party. Padma Sunder Lawoti became the vice-chairman of the party.
Chairman Kamal Thapa resigned from his post and Rabindra Nath Sharma became the chairman of the party on 10th Karkik, 2063. Rabindra Nath Sharma resigned from the post of Chairman because of his poor health by the second week of Falgun, 2064 and the chairmanship of the party was handed over to Mr. Kamal Thapa again. Presently Padma Sundar Lawati is the vice chairman of the party.
