A part from antartica which has been split in several "under control sectors" there is a territory which belongs to no one or is no claim by anyone Bir Tawil.
Bordering Egypt and Sudan, it’s a trapezoid-shaped piece of land. Bir Tawil is made up of desert and mountains and is lacking any valuable natural resources. The reason behind the two countries’ “generosity”?
Both want the prettier, more useful older sister of Bir Tawil — Hala’ib, a piece of land that is much larger and comprised of rich soil. Under the border treaty from 1899, Hala’ib belongs to Egypt. Under the 1902 treaty, that land belongs to Sudan and Bir Tawil belongs to Egypt. Both recognize the treaty that gives them Hala’ib, as it’s the better end of the deal, leaving Bir Tawil owner-less.
Somebody already put a flag and start building a new nation!
Here this guy give more details information about this "precious" peace of land!
