The Second Congo War, also known as Africa's World War or the Great War of Africa, was a major conflict that began on 2 August 1998, in the Democratic Republic of the Congo, just over a year after the First Congo War. The war initially erupted when Congolese president Laurent-Désiré Kabila turned against his former allies from Rwanda and Uganda, who had helped him seize power. The conflict expanded as Kabila rallied a coalition of other countries to his defense. The war drew in nine African nations and approximately 25 armed groups, making it one of the largest wars in African history.
Although a peace agreement was signed in 2002, and the war officially ended on 18 July 2003 with the establishment of the Transitional Government of the Democratic Republic of the Congo, violence has persisted in various regions, particularly in the east, through ongoing conflicts such as the Lord's Resistance Army insurgency and the Kivu and Ituri conflicts.
The Second Congo War and its aftermath caused an estimated 5.4 million deaths, primarily due to disease and malnutrition, making it the deadliest conflict since World War II, according to a 2008 report by the International Rescue Committee. However, this figure has been disputed, with some researchers arguing that many of the deaths may have occurred regardless of the war and that the actual death toll was closer to 3 million. The conflict also displaced approximately 2 million people, forcing them to flee their homes or seek asylum in neighboring countries. Additionally, the war was heavily funded by the trade of conflict minerals, which continues to fuel violence in the region.
