France and the Rwandan genocide
The role of France in the 1994 genocide against the Tutsi has been a source of controversy and debate both within and beyond France and Rwanda. France actively supported the Hutu-led government of Juvénal Habyarimana against the Tutsi-dominated Rwandan Patriotic Front, which since 1990 had been engaged in a conflict intended to restore the rights of Rwandan Tutsis both within Rwanda and exiled in neighboring countries following over four decades of anti-Tutsi violence. France provided arms and military training to Habyarimana's militias, the Interahamwe and Impuzamugambi, which were among the government's primary means of operationalizing the genocide following the assassination of Juvénal Habyarimana and Cyprien Ntaryamira on April 6, 1994.
Near the end of the 100-day genocide, on June 23, French troops were deployed to establish the Turquoise Zone, largely preventing further waves of genocide within the purported safe zone. However, the zone also enabled many Hutu perpetrators of the genocide to safely escape into Zaire out of reach from the advancing and victorious RPF soldiers. The facts related to the French role in the 1994 genocide against the Tutsi have formed the focus of ongoing debate, and diplomatic relations between France and Rwanda have frequently been strained since 1994.
As a result of these actions and subsequent tensions between the two governments, after a progressive rift with the Kagame-led regime that has ruled Rwanda since 1994 (described in greater detail below), Rwanda repeatedly broke diplomatic relations with France; the Rwandan government shut down all French institutions in Rwanda, including schools and cultural organisations, with only some being subsequently reopened; the language of instruction in Rwandan schools "has even been switched from French to English"; and Rwanda successfully applied to join the British-led Commonwealth, thus becoming one of only two members that were not former British colonies.
