Darfur conflict (2003)
Rebels attacked government positions in Darfur, and Khartoum armed Arab militias known as the Janjaweed. The campaign killed hundreds of thousands and displaced millions.
The International Criminal Court charged President Omar al-Bashir with genocide and crimes against humanity.
The Janjaweed were later folded into the Rapid Support Forces, the paramilitary group now fighting the army.
The current war is partly a fight over the state that emerged from that conflict, with Darfur again a main battlefield.
