1995
The Communist Party of Nepal-Maoist (CPN-M) was established as a splinter group of the Communist Party of Nepal-Unity Center. Led by Prachanda, a radical group of dissidents of the Communist Party of Nepal formed the Maoist wing, and denounced the CPN for its participation in the country's parliamentary process.
1996
Feb. 13: CPN-M attacked police districts in northwestern Nepal and declared a "People's War."

CPN-M was involved in more than 1,600 separate insurgent acts between 2004 and 2005.
2005
February: King Gyanendra declared a state of emergency, including dismissing Nepal's parliament. Gyanendra's strategy seemed to backfire, engendering significant opposition by the Nepalese people. As a result, CPN-M was treated sympathetically by legitimate political parties.
2006
April: King Gyanendra announced that Parliament would re-assemble and that he would relinquish absolute power. This strategy shifted the domestic discord from violent insurgency followed by harsh countermeasures, toward a more political struggle. Towards the end of April, CPN-M announced a unilateral three-month cease-fire. Shortly after that, the interim Nepalese Parliament announced an indefinite cease-fire.
September: The United Nations High Commission on Human Rights called on CPN-M to refrain from abuses.
Nov. 21: The parliamentary government and the CPN-M signed an agreement providing for elections in June 2007 to decide whether the country would remain a monarchy. For an interim period, the CPN-M was invited to participate in the existing government. In return, the Maoists agreed to place thousands of fighters in camps where they would disarm and be monitored by the United Nations.
2007
January: Seventy-three CPN-M representatives were sworn in as members of the new Nepalese Parliament. This made CPN-M the second largest party in the government. The leader of the group, Prachanda, and his deputy, Baburam Bhattarai, did not join the legislature.

August: Rebels believed to be CPN-M attacked a police station and stole their weapons. The local Maoist commander denied his men were involved.
September: The CPN-M threatened to leave the government unless a list of 22 demands was met by the members of the governing coalition. CPN-M sought, among other demands, the abolition of the monarchy and the establishment of a republic prior to the upcoming elections. A series of bombing occurred in Kathmandu. The Nepalese army blamed Maoist rebels, who denied the allegations. The bombs may have been intended to disrupt the upcoming November elections.
Sept. 14: The U.N. Mission in Nepal (UNMIN) reported the movement of large numbers of Maoist personnel outside the main cantonment site in Nawalparasi and its satellite sites, violating commitments regarding the management of arms made by the Maoists in 2006 with the interim government.
Sept. 18: Five Maoist ministers who had assumed Cabinet positions in April 2007 resigned over the issue of declaring Nepal a republic and the use of proportional representation voting methods. The communists maintained that they were not abrogating the cease-fire with the government.
October: Elections in Nepal were indefinitely postponed after the seven main parties were unable to come to a compromise regarding the electoral system and the monarchy. Possible fractures in the CPN-M developed. A splinter party, CPN-M (United Rebel Front), emerged.
November: The United Nations called on the CPN-M to abide by its commitments concerning child soldiers under the age of 18. The U.N. High Commissioner for Human-Rights (Nepal) said the Maoists had violated the rights of children by forcing them to return to CPN-M after the youths had voluntarily left.
December 30: The CPN-M ended its 3.5-month separation from the government as Prime Minister Girija Prasad Koirala appointed five party members to ministerial positions in the interim Cabinet. The boycott ended after compromises were reached over the establishment of the constituent assembly.
Numerous attacks and kidnappings throughout 2007 were attributed to CPN-M members.

The constituent assembly convened to draft a new constitution.
