Was a state of Libertia bassed on the west side of Bir Tawil.
Petru knew that Bir Tawil is unclaimed, so he claimed the west. At first Bir Tawil was just a teritory but after that it became a state. Nowdays it isn't part of Libertia as of the Libertinian Reforms.
The flag is made of a trapezoid, which represents Bir Tawil's geometrical form and inside it says ,,Bir Tawil" in Arabic (Because Bir Tawil is in an Arabic speaking zone) and yellow because it is one of Libertia's colours.
