After acquiring all the land along the Great Lakes Region, these new territories needed to be divided into new administrative districts to facilitate administration and statistical record-keeping.
This included Northern Kenya, which had previously remained in a temporary state without administrative divisions.
This time, with the expansion brought by the Northwestern War, the land west of Lake Turkana around Omorate Town also fell into East Africa's hands.
Previously, the East African colony had no presence on the western shore of Lake Turkana. Lake Turkana itself was a natural barrier that had hindered East Africa's expansion.
Moreover, the south had been cut off by the Kingdom of Buganda and numerous tribes, making it difficult for Western Kenya District to develop westward.
Now that the entire Great Lakes shoreline had fallen into the East African colony's hands, it took the opportunity to bring all the land west of Lake Turkana, stretching as far as Lake Frederick (Lake Albert), into its fold.
Because many areas west of Lake Turkana had climates similar to Northern Kenya—arid and short of water—they were unsuitable for agriculture.
Thus, the arid lands west of Lake Turkana and Northern Kenya were regarded as the same region. In his previous life, this area had also belonged to Northern Kenya, except East Africa occupied it somewhat later than the eastern part in this timeline.
This region contained many seasonal rivers, which could be considered one of its distinctive characteristics.
Furthermore, throughout the northern part of the East African colony, only the Omo River basin on the northern shore of Lake Turkana was suitable for large-scale agricultural cultivation. Ernst simply designated all of Northern Kenya and the Omo River basin as the Northern District.
Its capital was set in Omorate Town. Since the northern climate was arid and many places were pastoral
