Answer
Rwanda and Uganda played pivotal roles in supporting Laurent Kabila's ascent to power in the Democratic Republic of the Congo (DRC) during the First Congo War (1996-1997). These neighboring countries provided crucial military and financial assistance to Kabila's rebel group, the Alliance of Democratic Forces for the Liberation of Congo (AFDL), enabling him to overthrow the regime of Mobutu Sese Seko and become president of the DRC.
