In short: Colonel Théoneste Bagosora was a central figure in the 1994 Rwandan genocide, a systematic campaign that claimed hundreds of thousands of lives in just 100 days. Often described as the chief organizer of the mass killings, his actions and influence helped dismantle the state and mobilize militias across the country.

Théoneste Bagosora, a career military officer who rose to the rank of colonel, became a pivotal figure in the Rwandan Ministry of Defence by 1992. His influence was deeply tied to the hardline Hutu Power ideology, and he was frequently associated with the akazu, an elite group surrounding the president's wife. While he officially retired from the military in September 1993, he maintained his powerful position as chief of staff within the ministry until he fled the country in July 1994.

The genocide was not a spontaneous eruption of violence but a calculated operation. The International Criminal Tribunal for Rwanda alleged that planning began as early as 1992. Bagosora was instrumental in establishing paramilitary self-defense units known as the Interahamwe and overseeing the mass distribution of weapons, including hundreds of thousands of machetes, across Rwanda. Following the assassination of President Juvénal Habyarimana on April 6, 1994, Bagosora moved to consolidate power, forming a crisis committee and facilitating the installation of a hardline interim government.

The consequences of his leadership were catastrophic. During the 100-day period of violence, an estimated 800,000 civilians, primarily Tutsi and moderate Hutu, were murdered. Bagosora's role was further underscored by his presence near the site where ten Belgian peacekeepers were executed, an event that triggered the withdrawal of international forces and left the population vulnerable. After fleeing to Zaire, he continued to organize military structures from refugee camps.

Bagosora was eventually captured and brought to trial at the International Criminal Tribunal for Rwanda. Initially sentenced to life imprisonment for his role in orchestrating the genocide, his sentence was reduced to 35 years on appeal in 2011. He remained in custody until his death in a Malian prison hospital in 2021, marking the end of a life defined by his central role in one of the 20th century's most severe humanitarian tragedies.
