Why did the genocide of Darfur begin?

Answer 1

During February 2003, the non-Arab ethnic groups of Darfur launched an uprising against the Kartoum government. The government responded by implementing their campaign of genocide, enlisting the help of Arab militia in Darfur called the Janjaweed ( the armed militia supported by the Sudanese Government to carry out the genocide, alongside and independent of, the Sudanese Army). The Janjaweed will enter a village on horse or camel back. They then set about causing as much mayhem and terror as possible: destroying houses and buildings, shooting the men, gang raping the women and children and shooting any who try to escape. The village is generally destroyed, families dispersed and separated, most killed. Those who manage to escape then attempt the long journey to an IDP (Internally displaced persons) camp.

And Darfur is region rich for its cattle raising and vast amount of oil. So Sudanese, the Arabic speaking government never wanted to lose this reach territory.
