Communism in Nepal traces its roots back to the pro-democracy movement of 1951, and the subsequent overthrow of the autocratic Rana regime and the establishment of democracy in Nepal. The communist movement in Nepal has split into factions multiple times and multiple factions have come together into a single fold at times as well. It has a history of getting banned from open political discourse, as well as multiple instances of embracing guerrilla insurgency, most notably, the Maoist insurgency in the 1990s and early 2000s that led to the Nepalese Civil War, claiming at least 17,000 lives.
