Countless wars have been fought over borders throughout history, and millions of people have lost their lives for this cause. Considering the amount of blood shed for land, it seems almost impossible for a piece of land to exist without an owner in any corner of the world.However, for 143 years, a region between Egypt and Sudan has not belonged to any country.
In 1899, the United Kingdom determined the border between Egypt and Sudan as the 22nd parallel of latitude. With the drawing of the border, the Hala'ib Triangle was left to Egypt and Bir Tawil to Sudan.
However, in 1902, the border of this region came back to the agenda. The British, who sat down at the table again for Bir Tawil in 1902, rearranged the administrative border taking into account the living spaces of the tribes living in the region at that time. With the new arrangement, Bir Tawil was given to Egypt and the Hala'ib Triangle to Sudan. However, Egypt did not claim Bir Tawil and left it to Sudan. When Sudan did not claim Bir Tawil, this region was defined with the concept of 'terra nullius', in other words, as a region that is not under the administration of any state in international law.
