The increase in immigration has undoubtedly endowed the East African colony with stronger development potential. However, the population growth has also intensified the colony's management challenges, especially due to the chaotic administrative planning currently in East Africa, adding difficulty to the colony's management.
This situation has compelled Ernst to systematically re-plan the administrative institutions of the East African colony, establishing a new administrative governance system. Under the new administrative divisions, it would be possible to better gather colonial data and implement plans according to specific situations.
For instance, the Marine District was established when the land and population reached a certain scale, and it temporarily became the highest administrative unit in the current East African colony.
