Refugees return with an army
On 1 October 1990, around 2,500 fighters of the Rwandan Patriotic Front crossed from Uganda into Rwanda, most of them Tutsi refugees or their children exiled since the 1959 revolution that had ended the Tutsi monarchy and driven over 300,000 people from the country. French troops helped push the initial invasion back toward the border within weeks, and the RPF regrouped as a guerrilla force under Paul Kagame after its first commander, Fred Rwigyema, was killed early in the fighting under circumstances still disputed between accounts of a stray bullet and a deliberate act by a rival officer. Low-intensity fighting continued for two years before a ceasefire and negotiations opened at Arusha in Tanzania in 1992.
Stalemate and Arusha
The war’s documentation splits between military and diplomatic records from the period and the far more extensive investigative work that followed the genocide it preceded. Ceasefire negotiations, RPF troop movements and government statements were recorded contemporaneously by journalists, the United Nations mission that arrived in 1993, and participants such as Roméo Dallaire, whose later testimony and a January 1994 warning cable to UN headquarters became central evidence for how much was known before April. Scholarship on the war’s radicalising effect on Hutu extremism, notably Gérard Prunier’s account of 1992 as the point when genocidal planning began to circulate, was written after the fact, drawing on trial records from the International Criminal Tribunal for Rwanda that only became available through the later 1990s and 2000s.
One assassination, two catastrophes
The war reflected a colonial-era hierarchy that Belgian administrators had entrenched by favouring Tutsi elites and fixing ethnic categories on identity cards from 1935, a structure the 1959 revolution inverted rather than dismantled. Economic crisis in the late 1980s weakened Habyarimana’s government just as Tutsi exiles in Uganda, some of whom had fought in Yoweri Museveni’s army, organised the political and military capacity to press their claim to return. Neither side achieved a decisive military result: the RPF’s February 1993 offensive advanced within thirty kilometres of Kigali before a unilateral ceasefire, and the resulting Arusha Accords of August 1993 offered power-sharing that excluded hardline Hutu parties altogether, radicalising exactly the actors most capable of derailing it.
A war won amid a massacre
Two questions remain genuinely open rather than merely under-researched. Responsibility for shooting down Habyarimana’s plane on 6 April 1994 has been investigated by French and Rwandan inquiries reaching opposite conclusions, with a 2006 French investigation implicating Kagame’s RPF and a 2010 Rwandan inquiry blaming Hutu extremists within the president’s own circle; a later French report cited as clearing the RPF has itself been contested by researchers such as Filip Reyntjens. Separately, historians dispute how far in advance the genocide was actually planned, since prosecutors at the international tribunal could not prove a long-standing conspiracy and the alleged chief planner, Théoneste Bagosora, was acquitted of conspiracy charges even while convicted of genocide itself.
What the record won’t settle
The civil war’s own combat toll, estimated at around 7,500 fighters killed, is dwarfed by what followed it: scholarly consensus now places genocide deaths at 500,000 to 600,000, mostly Tutsi, occurring within roughly one hundred days from April to July 1994 while the RPF resumed its advance and the international community, including a UN mission explicitly barred from using force beyond self-defence, largely failed to intervene. The RPF took Kigali on 4 July and secured the rest of the country by 18 July, ending the war and the genocide within days of each other, an outcome that has made the two events difficult to narrate separately even though they had different causes, timelines and, in the civil war’s case, a much smaller death toll.
A war that outlived its ceasefire
The war deserves attention on its own terms because the genocide it enabled has understandably absorbed most of the historical attention since. Reading the four years of stalled negotiation, refugee grievance and Hutu Power organisation that preceded April 1994 shows how a negotiated peace process, rather than preventing catastrophe, can supply the pretext extremists use to abandon restraint altogether. It also leaves an unfinished thread: the nearly two million refugees who fled into what was then Zaire after the RPF’s victory carried the conflict’s unresolved politics directly into the First Congo War two years later, a sequence that makes the 1994 ceasefire look less like an ending than a pause.
