The United Nations Mission in Sierra Leone (UNAMSIL) was a United Nations peacekeeping operation in Sierra Leone from 1999 to 2006. It was created by the United Nations Security Council in October 1999 to help with the implementation of the Lomé Peace Accord, an agreement intended to end the Sierra Leonean civil war. UNAMSIL expanded in size several times in 2000 and 2001. It concluded its mandate at the end of 2005, the Security Council having declared that its mission was complete.
The Sierra Leone Civil War (1991–2002), or the Sierra Leonean Civil War, was a civil war in Sierra Leone that began on 23 March 1991 when the Revolutionary United Front (RUF), with support from the special forces of Charles Taylor's National Patriotic Front of Liberia (NPFL), intervened in Sierra Leone in an attempt to overthrow the Joseph Momoh government. The resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead.
The Lomé Peace Agreement was a peace agreement signed on 7 July 1999 between the warring parties in the civil war that gripped Sierra Leone for almost a decade. President Ahmad Tejan Kabbah signed with the Revolutionary United Front (RUF) leader, Foday Sankoh and granted Sankoh a position in the transitional government as well as amnesty for him and all combatants. The accord is named for Lomé, the capital of Togo, where the negotiations took place and the agreement was signed.

The United Kingdom began a military intervention in Sierra Leone on 7 May 2000 under the codename Operation Palliser. Although small numbers of British personnel had been deployed previously, Palliser was the first large-scale intervention by British forces in the Sierra Leone Civil War. In early May 2000, the Revolutionary United Front (RUF)—one of the main parties to the civil war—advanced on the country's capital, Freetown, prompting the British government to dispatch an "Operational Reconnaissance and Liaison Team" (ORLT) to prepare to evacuate foreign citizens. On 6 May, the RUF blocked the road connecting Freetown to the country's main airport, Lungi. The next day, British soldiers began to secure the airport and other areas essential to an evacuation. The majority of those who wished to leave were evacuated within the first two days of the operation, but many chose to stay following the arrival of British forces.
