Context paragraphs:
Lord's Resistance Army insurgency: The Lord's Resistance Army insurgency is an ongoing guerrilla campaign waged by the Lord's Resistance Army (LRA) insurgent group since 1987.  Currently, there is low-level LRA activity in eastern Democratic Republic of the Congo and the Central African Republic.  The movement is led by Joseph Kony, who proclaims himself the "spokesperson" of God and a spirit medium.  It aims to overthrow Yoweri Museveni's Ugandan government and establish a theocratic state based on the Ten Commandments and Acholi tradition.

Lord's Resistance Army insurgency (1987–94): The period from 1986 to 1994 of the Lord's Resistance Army insurgency is the early history of the ongoing insurgency of the Lord's Resistance Army (LRA) rebel group in Uganda, which has been described as one of the most under-reported humanitarian crises in the world.  The Lord's Resistance Army was formed in early 1987 out of the conflict following the successful rebellion of the National Resistance Army (NRA), though remained a relative small group through the counterinsurgency of the NRA.  As the peace talks initiated by Minister Betty Bigombe failed Sudanese support to the LRA intensified the conflict.

Joseph Kony: Joseph R. Kony (] ; born likely 1961) is the leader of the Lord's Resistance Army (LRA), a guerrilla group that formerly operated in Uganda.

2006–08 Juba talks: The Juba talks were a series of negotiations between the government of Uganda and the Lord's Resistance Army rebel group over the terms of a ceasefire and possible peace agreement.  The talks, held in Juba, the capital of autonomous Southern Sudan, began in July 2006 and were mediated by Riek Machar, the Vice President of Southern Sudan.  The talks, which had resulted in a ceasefire by September 2006, were described as the best chance ever for a negotiated settlement to the 20-year-old war.  However, LRA leader Joseph Kony refused to sign the peace agreement in April 2008.  Two months later, the LRA carried out an attack on a Southern Sudanese town, prompting the Government of Southern Sudan to officially withdraw from their mediation role.

Grace Akallo: Grace Akallo (born 1981) is a Ugandan woman who, at the age of 15, while attending a Catholic school, was abducted by Joseph Kony to be used as a child soldier in the Lord's Resistance Army (LRA).  As part of her initiation into the army, she was forced to kill another girl, a very common practice among armies that employ child soldiers.  She remained in the LRA for seven months, during which Akallo became a skilled AK-47 user.  She was raped and became a sexual slave.  She was eventually rehabilitated and became a mother.

Lord's Resistance Army insurgency (2002–05): The period from 2000 to 2006 of the Lord's Resistance Army insurgency in northern Uganda begins with the assault of the Uganda People's Defence Force (UPDF) upon LRA strongholds in South Sudan.  This in turn led to a series of retaliatory attacks by the Lord's Resistance Army of an intensity not seen to since the mid-1990s.  International awareness of the conflict gradually grew and in September 2005, the International Criminal Court issues warrants for the arrest of senior LRA commanders, including Joseph Kony.

Raska Lukwiya: Raska Lukwiya (died August 12, 2006) was the third highest-ranking leader of the Lord's Resistance Army rebel group founded in northern Uganda.  Believed to be a native of Uganda's northern Gulu District, Lukwiya served successively as Brigade General, Deputy Army Commander and Army Commander of the LRA, the last being the highest LRA rank after those held by Joseph Kony and Vincent Otti.

Lord's Resistance Army: The Lord's Resistance Army (LRA), also known as the Lord's Resistance Movement, is a rebel group and heterodox Christian cult which operates in northern Uganda, South Sudan, the Central African Republic, and the Democratic Republic of the Congo.  Originally known as the United Holy Salvation Army and Uganda Christian Army/Movement, its stated goals include establishment of multi-party democracy, ruling Uganda according to the Ten Commandments, and Acholi nationalism, though in practice "the LRA is not motivated by any identifiable political agenda, and its military strategy and tactics reflect this".  It appears to largely function as a personality cult of its leader Joseph Kony, a self-declared prophet whose leadership has earned him the nickname "Africa's David Koresh".

Human trafficking in Uganda: Uganda is a source and destination country for men, women, and children trafficked for the purposes of forced labor and sexual exploitation.  Ugandan children are trafficked within the country, as well as to Canada, Egypt, the United Arab Emirates, and Saudi Arabia for forced labor and commercial sexual exploitation.  Karamojong women and children are sold in cattle markets or by intermediaries and forced into situations of domestic servitude, sexual exploitation, herding, and begging.  Security companies in Kampala recruit Ugandans to serve as security guards in Iraq where, at times, their travel documents and pay have reportedly been withheld as a means to prevent their departure; these cases may constitute trafficking.  Pakistani, Indian, and Chinese workers are reportedly trafficked to Uganda, and Indian networks traffic Indian children to the country for sexual exploitation.  Children from the Democratic Republic of the Congo (D.R.C.), Rwanda, and Burundi are trafficked to Uganda for agricultural labor and commercial sexual exploitation.  Until August 2006, the terrorist rebel organization, Lord’s Resistance Army (LRA), abducted children and adults in northern Uganda to serve as soldiers, sex slaves, and porters; while no further abductions of Ugandan children have been reported, at least 300 additional people, mostly children, were abducted during the reporting period in the Central African Republic and the D.R.C.  The Government of Uganda does not fully comply with the minimum standards for the elimination of trafficking; however, it is making significant efforts to do so.
