Between Egypt and Sudan, Bir Tawil is known as a region described as “terra nullius”, what is it in English?

Bir Tawil, an area of land between Egypt and Sudan is a region designated as “terra nullius” or “nobody’s land”. It is an 800 square mile (2,060 square kilometer) region that was created from a discrepancy between borders drawn in 1899 and 1902. The region is sometimes referred to as the Bir Tawil Triangle, even though the shape is four-sided. Bir Tawil is uninhabited, although members of some tribes do pass through the area, and the area is claimed by neither Egypt nor Sudan. The nearby Halaib Triangle, a disputed area that arose from the same borders drawn in 1899 and 1902 is claimed by both countries. In 1994, Egypt took control by moving its military into the region.

“Terra nullius” comes from Latin, the term is used in international law and the territory that is described as “terra nullius” can be acquired by a country by occupation. As of 2023, there are three territories categorized as “terra nullius”, Bir Tawil, sections of land near the Danube River due to the Croatia-Serbia border dispute that dates to 1947, and parts of Antarctica.
