The foundation of East Africa lies in the East African Plateau, approximately one million square kilometers, primarily covering Tanzania, Kenya, and the Great Lakes Region. This is an already stabilized territory, and with some surrounding areas, the East African Kingdom has no fear of competition from any forces on nearly two million square kilometers of land.
With the advantage of a larger number of immigrants, even with the addition of all indigenous forces, other colonizers find it hard to pose a threat to the East African Plateau and its surrounding areas.
Now, the southwest region, namely the former Zambia region, because it was only recently incorporated, has instead become the vulnerable area of the East African Kingdom, which has made temporary concessions to the local indigenous forces.
