The Nepali Civil War (labelled People's War by the Maoists) was a conflict between government forces and Maoist fighters in Nepal which lasted from 1996 until 2006. The war was started by the Communist Party of Nepal (Maoist) on 13 February 1996, with the aim of overthrowing the Nepalese monarchy and establishing the "Federal Republic of Nepal." It ended with a Comprehensive Peace Accord signed on 21 November 2006.

More than 15000 people were killed (6000 by Maoists and 9000 by the government) and an estimated 100,000 to 150,000 people were internally displaced as a result of the conflict. This conflict disrupted the majority of rural development activities and led to a deep and complex Left Front which, together with the Nepali Congress, was the backbone of the broadbased movement for democratic change. However, communist groups uncomfortable with the alliance between ULF and Congress formed a parallel front, the United National People's Movement. The UNPM called for elections to a Constituent Assembly, and rejected compromises made by ULF and Congress with the royal house. In November 1990 the Communist Party of Nepal (Unity Centre) was formed, including key elements of constituents of UNPM. The new party held its first convention in 1991, the adopted a line of "protracted armed struggle on the route to a new democratic revolution" and that the party would remain an underground party. The CPN(UC) set up Samyukta Jana Morcha, with Baburam Bhattarai as its head, as an open front ten contest elections. In the 1991 elections, SJM became the third force in the Nepali parliament. However, disagreements surged regarding which tactics were to be used by the party. One sector argued for immediate armed revolution whereas others (including senior leaders like Nirmal Lama) claimed that Nepal was not yet ripe for armed struggle.

A civil war is a war between organized groups within the same nation state or republic, or, less commonly, between two countries created from a formerly united nation state. The aim of one side may be to take control of the country or a region, to achieve independence for a region, or to change government policies. The term is a calque of the Latin bellum civile which was used to refer to the various civil wars of the Roman Republic in the 1st century BC.

A civil war is a high-intensity conflict, often involving regular armed forces, that is sustained, organized and large-scale. Civil wars may result in large numbers of casualties and the consumption of significant resources.

Civil wars since the end of World War II have lasted on average just over four years, a dramatic rise from the one-and-a-half year average of the 1900-1944 period. While the rate of emergence of new civil wars has been relatively steady since the mid-19th century, the increasing length of those wars resulted in increasing numbers of wars ongoing at any one time. For example, there were no more than five civil wars underway simultaneously in the first half of the 20th century, while over 20 concurrent civil wars were occurring at the end of the Cold War, before a significant decrease as conflicts strongly associated with the superpower rivalry came to an end. Since 1945, civil wars have resulted in the deaths of over 25 million people, as well as the forced displacement of millions more. Civil wars have further resulted in economic collapse; Burma (Myanmar), Uganda and Angola are examples of nations that were considered to have promising futures before being engulfed in civil wars.
