 In this invasion Rwanda allied with Laurent Kabila, a progressist revolutionary in Eastern Zaire who had been a foe of Zaire's long-time dictator, Mobutu Sese Seko.In addition to Rwandan forces, Laurent Kabila's AFDL (Alliance of Democratic Forces for the Liberation of Congo) forces were also supported by Ugandan forces, with whom Kagame had trained in the late 1980s, which then invaded Eastern Zaire from the northeast.This became known as the First Congo War.
