On the night of April 6, 1994, a plane carrying Rwandan President Juvénal Habyarimana and Burundian President Cyprien Ntaryamira was shot down as it approached Kigali.
Within hours, roadblocks appeared across Rwanda’s capital. Soldiers and militia members began searching homes and checking identity cards. Among the first people murdered were political opponents and moderate officials who might have resisted the extremists including Rwanda’s prime minister, Agathe Uwilingiyimana.
Then the killing spread.
For approximately 100 days, extremist leaders directed a campaign to destroy Rwanda’s Tutsi population. Moderate Hutus and others who opposed the massacres were also murdered. Neighbors were turned against neighbors, families were separated, and people seeking protection in churches, schools and public buildings were attacked.
By the time the killing ended, approximately 800,000 people had been murdered.
But the genocide did not begin with the plane crash. Its foundations had been laid over decades.
Identities Turned into Political Weapons
Rwanda’s Hutu and Tutsi identities existed long before European colonization, but they were not always the rigid racial categories they later became. People shared a language, culture and homeland, and the boundaries between the groups could be more socially complex than colonial officials claimed.
Under German and especially Belgian rule, colonial authorities hardened these identities. Believing that Tutsis were racially superior and better suited to govern, the colonial administration ruled largely through the Tutsi monarchy and a favored Tutsi elite. Tutsis were given disproportionate access to administrative posts, influential employment and higher education, while the Hutu majority supplied much of the forced labor and remained largely excluded from power. Identity documents then formally classified every person as Hutu, Tutsi or Twa.
This unequal system created powerful resentment among many Hutus, who came to associate Tutsi authority with colonial domination. Some Tutsi leaders had benefited from and supported the colonial order, but the advantages were not shared equally by every Tutsi, just as Hutu resentment did not mean that every Hutu hated Tutsis. Near the end of colonial rule, Belgium shifted its support toward emerging Hutu political leaders. The 1959 Hutu Revolution overthrew the Tutsi monarchy, and violence forced large numbers of Tutsis into exile.
After independence in 1962, power passed to Hutu-led governments. The former colonial hierarchy had been reversed, but its racial categories and accumulated grievances remained. Political leaders could now present discrimination and violence against Tutsis as historical revenge for earlier domination.
The political hierarchy had changed, but identity remained a weapon.
Civil War and the Rise of Extremism
In 1990, the Rwandan Patriotic Front, or RPF a rebel movement formed largely by Tutsi exiles invaded Rwanda from Uganda. The invasion began a civil war and intensified fear inside the country.
President Habyarimana’s government faced military pressure from the RPF and growing demands for political reform. In 1993, the government and the RPF signed the Arusha Accords, which were intended to end the war and establish a power-sharing government.
For extremists who feared losing power, compromise was a threat.
Militias were trained and armed. Lists of suspected opponents were prepared. Extremist newspapers and radio broadcasts portrayed Tutsis as enemies and encouraged violence. The language of extermination entered everyday political messaging.
The plane crash on April 6 became the immediate pretext for a killing campaign that had already been prepared. Responsibility for shooting down the aircraft remains disputed, but what followed was not a spontaneous reaction. It was organized.
The Machinery of Genocide
Presidential guards, government soldiers, local officials and militias—including the Interahamwe—played central roles in the massacres. Roadblocks allowed killers to identify victims. Local authorities summoned people to supposed places of safety or directed attackers toward those in hiding.
Radio Télévision Libre des Mille Collines helped turn propaganda into action. Its broadcasts spread dehumanizing messages, identified targets and encouraged participation in the killing.
The genocide also depended on coercion, fear and the deliberate destruction of social trust. Some Hutus risked their lives to hide or rescue Tutsis. Others were threatened or killed for refusing to participate. The existence of rescuers remains essential to the history: even inside an organized system of terror, people still made moral choices.
A World That Withdrew
United Nations peacekeepers were already in Rwanda to support the Arusha peace agreement. Their commander, Lieutenant-General Roméo Dallaire, warned UN officials in January 1994 that an informant had described weapons caches, militia training and plans to kill Tutsis.
The peacekeeping mission had a limited mandate and lacked the political backing and military strength required to stop a nationwide extermination campaign. After ten Belgian peacekeepers were murdered, Belgium withdrew its contingent. On April 21 while mass killing was underway—the UN Security Council reduced the mission from roughly 2,500 personnel to about 270.
Foreign governments concentrated on evacuating their own citizens. Major powers avoided committing the forces necessary to stop the genocide and hesitated to describe the violence by its proper legal name.
Individual peacekeepers and aid workers protected thousands of people wherever they could. But courage on the ground could not replace the international intervention that never came.
The world did not fail because it had no warning. It failed because governments with the ability to act chose not to accept the cost and risk of acting.
How the Killing Ended
The genocide ended not through international rescue but through the military victory of the RPF. Led by Paul Kagame, RPF forces advanced across the country and captured Kigali in July 1994. The extremist government collapsed, and enormous numbers of people fled into neighboring countries—among them civilians, defeated soldiers and perpetrators of the genocide.
The consequences did not remain inside Rwanda. Armed groups reorganized in refugee camps across the border in what was then Zaire, helping destabilize the region and contributing to the wars that later devastated the Democratic Republic of the Congo.
Justice, Reconstruction and Memory
After the genocide, Rwanda faced an almost unimaginable task: burying the dead, caring for survivors, rebuilding institutions and pursuing justice in a country where the legal system had been shattered.
The United Nations created the International Criminal Tribunal for Rwanda. Its judgments helped establish important legal precedents, including recognition that sexual violence committed with the intent to destroy a protected group can constitute genocide. Inside Rwanda, national courts and community-based gacaca courts processed large numbers of cases, though the system also attracted criticism over due process and the quality of justice.
Rwanda rebuilt with remarkable speed and placed national unity at the center of public life. Yet reconstruction could not erase the trauma, and the genocide’s political and regional consequences continue to shape Central Africa.
Memory therefore serves more than one purpose. It honors those who were murdered and those who survived. It also challenges the comforting belief that genocide arrives without warning.
Rwanda’s warning signs were visible: political leaders exploited identity, armed groups were prepared, propaganda normalized elimination, and international officials received advance information. The killing became possible because these warnings were repeatedly ignored, minimized or treated as someone else’s problem.
The Rwandan genocide was carried out by people who made deliberate choices. It was also enabled by powerful institutions and governments that chose hesitation.
That is the enduring lesson of those 100 days: “Never again” has no meaning unless the world is willing to act before remembrance becomes the only thing left to offer.
