Two lines on the map
On January 19, 1899, Britain and Egypt signed the agreement establishing the Anglo-Egyptian Condominium over Sudan. It defined Sudan as the territory south of the 22nd parallel north. A straight line of latitude, it took no account of how people used the land.
On November 4, 1902, the British drew a separate administrative boundary. It placed a triangle of land north of the parallel, on the Red Sea coast around Halaib, under the administration of Khartoum, because the Beja peoples who used it were linked to Sudan. It placed a smaller area south of the parallel, Bir Tawil, under the administration of Cairo, because it was grazing land used by the Ababda, who were linked to the Aswan area in Egypt.
For half a century the difference mattered little: both territories were under the same imperial system. It began to matter when Sudan became independent on January 1, 1956.
The trade-off: Halaib versus Bir Tawil
The Halaib Triangle covers about 20,580 km² and has a Red Sea coastline, a port, fishing grounds, and mineral potential. Bir Tawil covers about 2,060 km² of landlocked desert with no surface water.
Egypt claims the 1899 line, which gives it Halaib. That line puts Bir Tawil in Sudan. Sudan claims the 1902 line, which gives it Halaib. That line puts Bir Tawil in Egypt. Neither state can claim both areas without contradicting itself, and each prefers the larger and more valuable one. Claiming Bir Tawil would amount to conceding Halaib.
- Egypt's line (1899): Halaib in Egypt, Bir Tawil in Sudan.
- Sudan's line (1902): Halaib in Sudan, Bir Tawil in Egypt.
- Result: both claim Halaib; neither claims Bir Tawil.
How the dispute developed
The dispute first came to a head in 1958, when Egypt sought to include Halaib in a national plebiscite and Sudan objected. Tensions eased without a settlement. In the early 1990s the issue returned over oil-exploration rights off the coast, and from the mid-1990s Egypt took control of Halaib on the ground. Egypt has administered it since, and Sudan continues to protest and to claim it.
Throughout, Bir Tawil has remained outside both states' claims. Neither government has sought international arbitration of the boundary as a whole.
What this means for Bir Tawil today
Bir Tawil's status is a by-product of a dispute about somewhere else. It remains unclaimed by any state so long as Egypt and Sudan hold their current positions on Halaib. A settlement of the Halaib question could change that.
In the meantime, the territory has attracted claims from private parties. The current claim is that of the Sovereign Empire of Brendania, proclaimed on October 21, 2026 under Emperor Brendan Smith I. The Empire has written to Egypt and Sudan, and its declared policy is peaceful engagement with both.
Frequently asked questions
Why does no country claim Bir Tawil?
Because claiming it would mean accepting the boundary that gives the larger Halaib Triangle to the other country. Egypt and Sudan both prefer to claim Halaib, so both decline Bir Tawil.
Why doesn't Egypt claim Bir Tawil?
Egypt claims the 1899 border along the 22nd parallel, which gives it the Halaib Triangle but places Bir Tawil in Sudan.
Why doesn't Sudan claim Bir Tawil?
Sudan claims the 1902 administrative border, which gives it the Halaib Triangle but places Bir Tawil in Egypt.
Could Egypt or Sudan ever claim Bir Tawil?
Possibly, if the Halaib dispute were settled. Until then, each state's legal position requires it to treat Bir Tawil as the other's territory.
