Who played a key role in the Hutu class becoming the rulling power in Rwanda? How did they do it?

This week marks 20 years since the start of the genocide in Rwanda, so the world has spent some time reflecting on one of the most horrifying — and most defining — events in post-Cold War history.

Explanation:

What happened

The Rwandan genocide was a systematic campaign by the Hutu ethnic majority aimed at wiping out each and every member of the minority Tutsi group. The Hutu-controlled government and allied militias slaughtered between 800,000 and one million Tutsis before a Tutsi rebel group overthrew them. Over 100,000 Hutus were also killed, including both moderate Hutus killed by Hutu extremists and those killed by Tutsis in so-called "revenge killings."

The genocide was set into motion by the death of Rwandan President Juvénal Habyarimana. On April 6th, 1994, Habyarimana's plane was shot down by a missile of unknown origin. Government-aligned forces used (Hutu) Habyarimana's death as an excuse to begin a campaign of slaughter they had been planning for some time, and the genocide began on April 7th. It went on for about 100 days.

The story behind the Rwandan genocide begins with colonialism

The split between Hutus and Tutsis arose not as a result of religious or cultural differences, but economic ones. "Hutus" were people who farmed crops, while "Tutsis" were people who tended livestock. Most Rwandans were Hutus. Gradually, these class divisions became seen as ethnic designations.
