Bir Tawil

About 2,000 km² of desert between Egypt and Sudan that neither country claims. Each claims the colonial line that gives it the larger, richer Hala’ib Triangle by the Red Sea, and under either line Bir Tawil falls to the other side.

Two lines from one government

In 1899 Britain and Egypt agreed to run Sudan jointly, as a condominium. The Anglo-Egyptian Agreement of 19 January 1899 set the boundary with Egypt at the 22nd parallel.[2] In 1962 the US Geographer reported that the line had been defined on paper but never marked on the ground.[2]

Three years later a second line appeared. By an order of 25 July 1902 and a decree of 4 November 1902, Egypt’s Minister of the Interior drew an administrative boundary near the Red Sea.[2] It was meant to keep nomadic groups and their wells under one administration: the Bisharin under Sudan’s government, the Ababda under Egypt’s.[2] The new line put an area north of the 22nd parallel, by the Red Sea, under Sudan’s administration, and a smaller area south of the parallel under Egypt’s.[2] The first is the Hala’ib Triangle; the second is Bir Tawil.[1]

“The word ‘Soudan’ in this Agreement means all the territories south of the 22nd parallel of latitude…”[2]

Why neither side wants it

After Sudan became independent in 1956, Egypt treated the 1899 line as the border and Sudan treated the 1902 line as the border.[1] On 1 February 1958 Egypt asked Sudan to hand back everything north of the 22nd parallel. In return it offered to hand over the area it ran south of the parallel.[2] Sudan answered that Egypt had not complained when two earlier Sudanese elections were held in the northern territories.[2]

So both countries claim Hala’ib, and neither claims Bir Tawil. Claiming Bir Tawil would mean accepting the line the other side relies on, and with it giving up Hala’ib.[1] Hala’ib is about ten times the size, has a coast, minerals and offshore resources, and about 27,000 people. Bir Tawil is desert with no permanent population.[1]

In 2014 an American, Jeremiah Heaton, travelled to Bir Tawil, planted a flag, and named it the “Kingdom of North Sudan” so that his daughter could be a princess. He did not move there.[1]

The Hala’ib Triangle

For decades after independence both countries sent administrators to Hala’ib, and they lived in an uneasy co-existence.[3] In the early 1990s Sudan gave a Canadian oil company rights to explore off Hala’ib’s coast. Egypt objected strongly, and two years later the company pulled out until the question of sovereignty was settled.[3]

In 1995 President Hosni Mubarak survived an assassination attempt in Addis Ababa, and Egypt partly blamed Sudan. He then ordered Egyptian troops into Hala’ib, and Sudan’s administrators were expelled.[3][1] The Egyptian flag flies there today. Sudan has never accepted Egypt’s control and still counts the triangle as its own.[3][1]
