[2] NRA was formed in 1981 when Yoweri Museveni's Popular Resistance Army (PRA) merged with ex-president Yusuf Lule's group, the Uganda Freedom Fighters (UFF).
By the time the victorious NRA entered Kampala in 1986, about a quarter of its 16,000 combatants were Banyarwanda[citation needed], while Fred Rwigema was its deputy commander.
[5] Despite repeated government claims that the NRA had defeated the UNLA and other rebel groups, insurgent activity continued, especially in the northern, eastern, and western regions.
In April 1988, 3,000 former Uganda People's Army (UPA) fighters and members of several other small rebel groups accepted a government amnesty by surrendering and declaring their support for Museveni's regime.
In June 1988, the president concluded a peace agreement with Uganda People's Democratic Army (UPDA) commander Lieutenant Colonel John Angelo Okello.
