3. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. It is home to numerous tribal groups, many of which have a long history of intermarriage and economic cooperation. All are black, African, and Muslim.

4. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Since violence broke out in 2003, tribal groups have increasingly identified themselves as either African or Arab. U.S. politicians, journalists, and celebrities have also described Darfuris in these terms.

5. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. The roots of today’s ongoing conflict date back to 1916, the year British forces invaded Darfur to put down an uprising against Sudan’s British and Egyptian rulers. Darfur at that time was an autonomous region.

6. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. After the war, British administrators made Darfur part of Sudan and divided it into several regions, or dars.

7. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Each dar had a tribal leader and a tribal court, which resolved disputes over water rights and land and animal ownership.

8. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Conflicts often broke out between herders (who were mostly Arabs) and farmers (who were mostly Africans). The tribal courts prevented these conflicts from getting out of hand.

9. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. After the British left Sudan in 1956, competition for political offices arose among Darfur’s Arabs and Africans.

10. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. The Arabs, who formed a slight majority, looked to elections as a means of ending centuries of largely non-Arab rule, while the large African tribes, notably the Fur, saw elections as a chance to legitimize their historic hold on political power in Darfur.

11. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Electoral disputes soured relations between these groups. But no outright tribal warfare erupted, with tensions eased by a relative abundance of fertile land and by region-wide anger at the failure of the Sudanese government in Khartoum to adequately fund programs in Darfur.

12. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. In the 1980s, a series of droughts in Darfur worsened inter-tribal relations. As good agricultural land became scarce, African farmers who had traditionally allowed Arab herders to graze cattle on their farms began barring access.

13. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Stripped of their livelihood, many young Darfuri Arabs were recruited by Libyan leader Muammar Qaddafi. In the late 1980s, they joined Arabs from other countries to fight for the establishment of the Arab Belt, an Arab super-state spanning most of northern Africa.

14. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Qaddafi’s Arabs were defeated by the Chadian army, leaving the Darfuri Arabs to return to their homes with guns and a dangerous ideology of Arab supremacy.

15. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Even while they fought each other, Darfuris from all tribes had traditionally found common cause in resenting the Sudanese government. This started to change in 1989, when Omar al-Bashir, an Arab general, came to power in a coup.

16. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. As president, Bashir surrounded himself by a cabal of ruthless, power-hungry military men who believed passionately that Sudan, and all its natural resources, belonged to the Arabs.

17. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. In 1992, these men ordered the Sudanese military to work with Arab militias in removing a non-Arab people, the Nuba, from a mountainous region in southern Darfur.

18. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Six years later, they orchestrated a similarly brutal campaign to take control of the oil fields in Sudan’s largely non-Arab southern half.

19. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. In 1999, a power struggle between President Bashir (left) and his second-in-command Hassan al-Turabi (right) landed Turabi in jail. Turabi had been instrumental in winning Darfuri support for Khartoum. An influential Islamist ideologist, he had convinced Darfuri Africans that they did not have to be Arabs to be good Muslims.

20. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. With Turabi gone, the few Darfuri Africans serving in Bashir’s government were quickly purged. They returned home to form one of Darfur’s two main rebel groups, the Justice and Equality Movement (JEM).

21. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. The other main rebel group was the Sudanese Liberation Army (SLA). In 2003, SLA rebels attacked government troops at Darfur’s El Fasher airport, demanding that Khartoum end its long neglect of the Darfur region.

22. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Rather than deal with the rebels’ demands, the Sudanese government armed Arab militias, the janjaweed, and charged them with putting down the Darfuri uprising.

23. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Starting in the summer of 2003, the janjaweed rode into African communities, killing and raping the inhabitants. Survivors fled in terror.

24. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. The lucky ones made it to refugee camps in Chad.

25. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Word of the atrocities spread in 2004, prompting the United Nations Security Council to pass a resolution calling on the Sudanese government to disarm the janjaweed.

26. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. No punishment was threatened for non-compliance, and collaboration between the Sudanese military and the janjaweed reportedly continued. Thousands more Darfuri Africans died, and entire villages were destroyed.

27. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Several thousand African Union troops arrived in 2004 and 2005 to serve as peacekeepers.

28. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. But, in a region bigger than California, there was a limit to what they could achieve. Attacks by the janjaweed persisted, and refugee camps filled up.

29. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Meanwhile, the rebels—never angels but for a long time far less violent than the janjaweed— complicated prospects for peace by fighting among themselves and attacking Arab herders and even some international aid workers.

30. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. Despite the mounting troubles, the Sudanese government and most of the SLA faction signed a peace agreement on May 5, 2006.

31. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. The agreement gave Darfuris much of what the rebels initially wanted, including a US$300 million payment and the right to form a regional government.

32. © 2007 ProQuest-CSA LLC. All rights reserved. © 2007 Getty Images, Inc. But the JEM and a small faction of the SLA held out for more. Their refusal to sign, coupled with skepticism about the Sudanese government’s commitment to disarm the janjaweed, have prevented observers from declaring the conflict over.
