The Nepali Congress is the country's biggest social-democratic political party and the country's largest political party overall. Since July 2021, it has been in power as the country's governing party. The Nepali Congress (NC) continues to be the most popular and biggest political party in Nepal at the local level, according to popular vote and membership.
NC is the only political party in Nepal to have been elected with a majority three times: in 1959, 1991, and 1999. The party has established a majority government in each of these elections. Additionally, it emerged as the single biggest party in the 2013 Constituent Assembly election and played an important role in the proclamation of the Nepalese Constitution, which was signed into law in 2015.
The Nepali National Congress and the Nepal Democratic Congress were merged in 1950 to create the Nepal Democratic Congress, which was based on democratic socialist principles. During the period between the demise of the Rana monarchy and the beginning of the Panchayat era, NC prime ministers were in charge of four administrations, including the first democratically elected government in Nepal, which was formed after the 1959 general election. Beginning in the 1990s, the party followed in the footsteps of other major, centre-left social-democratic parties in a process known as the Third Way, which saw them move closer to the political centre.
