Based on this, the Egyptian Ministry of the Interior issued an administrative decision on March 26, 1899 – in accordance with British policy – to amend the borders in this region so that they pass north of Halfa by twenty-five kilometers. Thus, the borders came to pass through the village of Adandan, located on the eastern bank of the Nile, and the village of Faras, located on the western bank of the Nile.

If we head east, we find that this line cuts through the lands of the Ababda and the Bisharin, separating the Sudanese Ababda from their main settlements in Egypt, and the Egyptian Bisharin from their main settlements in Sudan. Therefore, the Minister of the Interior issued an administrative decision on November 14, 1902, to amend the borders by incorporating the Jabal Alaba region (12,500 km²) into Sudan and the Jabal Bartzuba region (600 km²) into Egypt.

In any case, this astronomical political border, like astronomical borders in general, lacks a single basis of geographical principles for correct borders. There are no landforms that sever contact, nor is there a sudden transition.
